BEFORE YOU START SERVICE
• Read all instructions and safety instructions in this
manual and on your engine safety decals.
• Clean the work area and engine.
• Park the machine on a stable and level ground.
• Let the temperature of the engine decrease before
you start a job.
• Stop the engine, then remove the key.
• Disconnect the battery negative cable.
• Hang a "DO NOT OPERATE" tag in the operator
station.
WSM000001INI0002US0
START SAFELY
• Do not do the procedures below when you start the
engine.
– short across starter terminals
– bypass the safety start switch
• Do not make unauthorized modifications to the
engine. This can cause damage and decrease the
engine life.

OPERATE SAFELY
• Do not use the machine after you consume alcohol
or medication or when you are tired.
• Put on applicable clothing and safety equipment.
• Use applicable tools only. Do not use alternative
tools or parts.
• When 2 or more persons do servicing, make sure
that you do it safely.
• Do not touch the hot parts or parts that turn when the
engine operates.
• Do not remove the radiator cap when the engine
operates, or immediately after it stops. If not, hot
water can spout out from the radiator. Only remove
the radiator cap when it is at a sufficiently low
temperature to touch with bare hands. Slowly loosen
the cap to release the pressure before you remove it
fully.
• Released fluid (fuel or hydraulic oil) under pressure
can cause damage to the skin and cause serious
injury. Release the pressure before you disconnect
hydraulic or fuel lines. Tighten all connections before
you apply the pressure.
• Do not open a fuel system under high pressure.
The fluid under high pressure that stays in fuel lines
can cause serious injury. Do not disconnect or repair
the fuel lines, sensors, or any other components
between the fuel pump and injectors on engines with
a common rail fuel system under high pressure.
• Put on an applicable ear protective device (earmuffs
or earplugs) to prevent injury against loud noises.
• Be careful about electric shock. The engine
generates a high voltage of more than DC100 V in
the ECU and is applied to the injector.
WSM000001INI0004US0
PROTECT AGAINST HIGH PRESSURE SPRAY
• Spray from high pressure nozzles can penetrate the
skin and cause serious injury. Keep spray from
contacting hands or body.
• If an accident occurs, see a doctor immediately. Any
high pressure spray injected into the skin must be
surgically removed within a few hours or gangrene
may result.
Doctors unfamiliar with this type of injury should
reference a knowledgeable medical source.

AVOID HOT EXHAUST
• Servicing machine or attachments with engine
running can result in serious personal injury. Avoid
exposure and skin contact with hot exhaust gases
and components.
• Exhaust parts and streams become very hot during
operation. Exhaust gases and components reach
temperatures hot enough to burn people, ignite, or
melt common materials.
9Y1210651INI0015US0
EXHAUST FILTER CLEANING
• Servicing machine or attachments during exhaust
filter cleaning can result in serious personal injury.
Avoid exposure and skin contact with hot exhaust
gases and components.
• During auto or manual/stationary exhaust filter
cleaning operations, the engine will run at elevated
idle and hot temperatures for an extended period of
time. Exhaust gases and exhaust filter components
reach temperatures hot enough to burn people, or
ignite, or melt common materials.
9Y1210651INI0016US0
PREVENT A FIRE
• Fuel is very flammable and explosive under some
conditions. Do not smoke or let flames or sparks in
your work area.
• To prevent sparks from an accidental short circuit,
always disconnect the battery negative cable first
and connect it last.
• The battery gas can cause an explosion. Keep the
sparks and open flame away from the top of battery,
especially when you charge the battery.
• Make sure that you do not spill fuel on the engine.
WSM000001INI0005US1
KEEP A GOOD AIRFLOW IN THE WORK AREA
• If the engine is in operation, make sure that the area
has good airflow. Do not operate the engine in a
closed area. The exhaust gas contains poisonous
carbon monoxide.

INFORMATION
V3800-CR-TE4(C), V3800-CR-TIE4(C), WSM
DISCARD FLUIDS CORRECTLY
• Do not discard fluids on the ground, down the drain,
into a stream, pond, or lake. Obey related
environmental protection regulations when you
discard oil, fuel, coolant, electrolyte and other
dangerous waste.
WSM000001INI0007US1
PREVENT ACID BURNS
• Keep electrolyte away from your eyes, hands and
clothing. Sulfuric acid in battery electrolyte is
poisonous and it can burn your skin and clothing and
cause blindness. If you spill electrolyte on yourself,
clean yourself with water, and get medical aid
immediately.
WSM000001INI0008US1
PREPARE FOR EMERGENCIES
• Keep a first aid kit and fire extinguisher ready at all
times.
• Keep the emergency contact telephone numbers
near your telephone at all times.

[Example: Engine Model Name V3800DICR-TE4B-XXXX or V3800DICR-TIE4B-XXXX]
The emission controls previously implemented in various countries to prevent air pollution will be stepped up as
Nonroad Emission Standards continue to change. The timing or applicable date of the specific Nonroad Emission
regulations depends on the engine output classification.
Over the past several years, KUBOTA has been supplying diesel engines that comply with regulations in the
respective countries affected by Nonroad Emission regulations. For KUBOTA Engines, E4B will be the designation
that identifies engine models affected by the next emission phase (See the table below).
When servicing or repairing ###-E4B series engines, use only replacement parts for that specific E4B engine,
designated by the appropriate E4B KUBOTA Parts List and perform all maintenance services listed in the appropriate
KUBOTA Operator's Manual or in the appropriate E4B KUBOTA Workshop Manual. Use of incorrect replacement
parts or replacement parts from other emission level engines (for example: E3B engines), may result in emission
levels out of compliance with the original E4B design and EPA or other applicable regulations.Please refer to the
emission label located on the engine head cover to identify Output classification and Emission Control Information.
E4B engines are identified with "EF" at the end of the Model designation, on the US EPA label. Please note: E4B is
not marked on the engine.

NOTE
Engine Oil:
• Refer to the following table for the suitable American Petroleum Institute (API) classification of engine oil
according to the engine type and the Fuel Type.
Fuel Type
Engine oil classification (API classification)
Engines with DPF
Ultra Low Sulfur Fuel
[Sulfur Content
< 0.0015 % (15 ppm)]
CJ-4
• Engine oil should be API classification CJ-4.
• Change the type of engine oil according to the ambient temperature.
• When using oil of different brands from the previous one, be sure to drain all the previous oil before adding the
new engine oil.
• On DPF-equipped engines, part of the fuel may get mixed with engine oil during the regenerating process. This
may dilute the oil and increase its quantity. If the oil rises above the oil level gauge upper limit, it means the oil
has been diluted too much, resulting in a trouble. In such case, immediately change the oil for new one.
• If the interval of DPF regeneration becomes 5 hours or less, be sure to change the oil for new one.
Fuel:
• Cetane Rating: The minimum recommended Fuel Cetane Rating is 45. A cetane rating greater than 50 is
preferred, especially for ambient temperatures below −20 °C (−4 °F) or elevations above 1500 m (4921 ft).
• Diesel Fuel Specification Type and Sulfer Content % (ppm) used, must be compliant with all applicable emission
regulations for the area in which the engine is operated.
• DO NOT USE Fuels that have sulfer content greater than 0.0015 % (15 ppm).
• Diesel fuels specified to EN 590 or ASTM D975 are recommended.
• No.2-D is a distillate fuel of lower volatility for engines in industrial and heavy mobile service. (SAE J313 JUN87)
• These engines utilize Interim Tier 4 standards, the use of ultra low sulfer fuel is mandatory for these engines,
when operated in US EPA regulated areas. Therefore, please use No.2-D S15 diesel fuel as an alternative to
No.2-D, and use No.1-D S15 diesel fuel as an alternative to No.1-D for ambient temperature below −10 °C (14 °F).

• When biodiesel fuel is used, change the fuel filter cartridge, fuel hose and clamp bands with new ones at intervals
half of the usual ones.
IMPORTANT
• Be sure to use a strainer when filling the fuel tank, or dirt or sand in the fuel may cause trouble.
• Do not run the fuel tank level too low or completely out of fuel. You may experience improper engine
running and/or a DTC (Diagnostic Trouble Code) error code may be recorded in the Engine Control.
Additionally, fuel system bleeding may be necessary if air enters the fuel system.

Q Biodiesel fuel
[When the B7 blended fuel is used]
When the finally blended Biodiesel fuel is B7, make sure it conforms to the updated EN590 (European) standard.
Be also sure that the mineral oil diesel fuel, if used, conforms to the updated EN590 (European) standard and that
the B100 blend conforms to the updated EN14214 (European) standard.
[When the B5 blended fuel is used]
When the finally blended Biodiesel fuel is B5, make sure it conforms to the updated EN590 (European) standard.
Be also sure that the mineral oil diesel fuel, if used, conforms to the updated EN5950 (European) standard or the
ASTM D975 (U.S.) standard and that the B100 blend conforms to the updated EN 14214 (European) standard or the
ASTM D6751 (U.S.) standard.
Q Precautions in handling Biodeisel fuels
1. Keep the fuel tank full whenever possible to prevent water vapor from accumulating inside the fuel tank. Tighten
up the fuel tank filler cap to avoid the entry of moisture.
2. Routinely check the oil level before the operation. Also strictly follow the specified oil change intervals.
3. Biodiesel fuels (BDF) during the supply process or in the machine easily deteriorate due to oxygen, water, heat
and other foreign substances. With this in mind, take the following precautions.
• Do not leave those fuels in the fuel tank or a metallic drum longer than 3 months.
• Before storing the machine for a prolonged period, change such fuel for a conventional type of diesel fuel and
run the machine for 30 minutes or longer to clean up the fuel system.
4. Bear it in mind that Biodiesel fuels have the characteristics below. Referring to the servicing intervals specified in
the KUBOTA products' Operator's Manuals, be sure to maintain and clean up the fuel system, replace the fuel
hose with new ones and take other necessary measures. It is advisable to replace the fuel filter, fuel hose and
clamp bands with new ones after half the specified replacement intervals. (Compared with the use of mineral oil
diesel fuels, the filtration performance of fuel filters gets degraded earlier than expected.)
• Biodiesel fuels easily induce the growth of microorganisms and foul themselves. This may get the fuel system
corroded and the fuel filter clogged.
• In cold weather, some problems may occur: the clog of the fuel line or fuel system, starting failure, and other
unforeseen troubles.
• Biodiesel fuels easily soak up moisture, which means that they may contain higher moisture content than
conventional diesel fuels.
5. Palm oil-based Biodiesel fuels are inferior in low-temperature fluidity to soy-based and rapeseed-based Biodiesel
fuels. In cold season in particular, this may clog the fuel filter.
6. If Biodiesel fuels are spilt on a coated surface, the coating may get damaged. Immediately wipe the spill off the
surface.

5. CHECK AND MAINTENANCE
[1] DAILY CHECK POINTS
Check of Engine Oil Level
1. Make the engine level.
2. Pull out the dipstick (1) and clean it. Put in and pull it out again.
Make sure that the oil level is between the 2 notches.
3. If the level is too low, add new oil to the specified level.
IMPORTANT
• On Diesel Particulate Filter (DPF) equipped engines, part of
the fuel may get mixed with engine oil during the
regenerating process. This may dilute the oil and increase
its quantity. If the oil rises above the dipstick upper limit, it
means the oil has been diluted too much, resulting in a
trouble. In such case, immediately change the oil for new
one.
• When you use an oil of different brand or viscosity from the
previous, drain the remaining oil. Do not mix 2 different
types of oil.
NOTE
• When you examine the engine oil level, make sure that you
put it in a level position. If not, you cannot measure oil
quantity accurately.
• Make sure that you keep the oil level between the upper and
lower lines of the dipstick. Too much oil can decrease the
output or cause too much blow-by gas. On the closed
breather type engine, the port absorbs the mist and too
much oil can cause oil hammer.
But if the oil level is not sufficient, the moving parts of
engine can get a seizure.

2. Make sure that the fuel level is above the lower limit of the fuel
level gauge.
3. If the fuel level is too low, add fuel to the upper limit.
IMPORTANT
• When Biodiesel fuel is used, change the fuel filter cartridge,
fuel hose and clamp bands with new ones at intervals half
of the usual ones.
• Be sure to use a strainer when filling the fuel tank, or dirt or
sand in the fuel may cause trouble.
• Do not run the fuel tank level too low or completely out of
fuel. You may experience improper engine running and/or
a DTC (Diagnostic Trouble Code) error code may be

Check of Coolant Level
CAUTION
• Do not remove the radiator cap when the engine is hot.
Then loosen the cap slightly to release unwanted pressure
before you remove the cap fully.
1. Without recovery tank: Remove the radiator cap (1). Make sure
that the coolant level is immediately below the port.
With recovery tank (2): Make sure that the coolant level is
between FULL A and LOW B.
2. If the coolant level is too low, find out the cause that there is less
coolant. Case 1 If the coolant decreases by evaporation, add
only clean and soft water. Case 2 If the coolant decreases by
leak, add coolant of the same manufacturer and brand in the
specified mixture ratio (clean, soft water and L.L.C.). If you
cannot identify the coolant brand, drain all the remaining coolant
and add a new brand of coolant mix.
IMPORTANT
• When you add the coolant, release the air from the engine
coolant channels. The engine releases the air when it
shakes the radiator upper and lower hoses.
• Make sure that you close the radiator cap correctly. If the
cap is loose or incorrectly closed, coolant can flow out and
the engine can overheat.
• Do not use an anti-freeze and scale inhibitor at the same
time.
• Do not mix the different type or brand of L.L.C..

Q Anti-freeze
• There are 2 types of anti-freeze available: use the permanent
type (PT) for this engine.
• When you add anti-freeze for the first time, flush the water
jacket and radiator interior with clean, soft water several times.
• The brand of the anti-freeze and the ambient temperature have
an effect on the procedure to mix water and anti-freeze. Refer
to the SAE J1034 standard, especially to the SAE J814c.
• Mix the anti-freeze with clean, soft water, and then fill into the
radiator.
IMPORTANT
• Make sure that when you mix the anti-freeze and water, the
ratio of anti-freeze is less than 50 %.

* At 1.01 × 100000 Pa (760 mmHg) pressure (atmospheric). Use a radiator pressure
cap that lets the pressure collect in the cooling system to get a higher boiling point.
NOTE
• The above data is the industrial standards that shows the
minimum glycol content necessary in the concentrated
anti-freeze.
• When the coolant level decreases because of evaporation,
add clean, soft water only to keep the anti-freeze mixing
ratio less than 50 %. If there is a leakage, add anti-freeze
and clean, soft water in the specified mixing ratio.
• The anti-freeze absorbs moisture. Keep new anti-freeze in
a tightly sealed container.
• Do not use the radiator cleaning agents after you add
anti-freeze to the coolant. Anti-freeze contains an
anti-corrosive agent, which reacts with the radiator
cleaning agent to make sludge and cause damages to the
engine parts.

IMPORTANT
• Before ordering to a cleaning contractor, follow the
procedures below to make a Judgment on whether the
separated filter comp (DPF) is reusable.
1. Check to see that the surface of the removed filter comp (DPF)
on the exhaust gas outlet side is not darkened.
2. If the surface is darkened, check whether there is no crack or
loss of the sealing part of the vents on both ends of the filter
(inlet side and outlet side).
If the number of missing sealing parts exceeds the allowable
limit, the filter comp cannot be reused even after.
Number for Judgment of
non-reusability of filter
Allowable limit
Number of missing sealing
parts: 15 or more
3. Check whether there is no crack and loss of sealing part of the
vents on both ends of the filter (inlet side and outlet side).
If there are any cracks or losses of the ceramics element, the
filter comp (DPF) cannot be reused even if it is cleaned.
4. If it is judged that the filter comp (DPF) is not reusable, report
the result of the evaluation to the customer that requested the
filter cleaning and replace the filter comp (DPF) with a new one.

Judgment of Reuse of Filter Comp (DPF) After Cleaning
(Cleaning Contractor)
IMPORTANT
• After the cleaning contractor has cleaned the filter comp
(DPF), measure the quantity of remaining ash in the
following procedure, and evaluate the reusability.
1. After having cleaned the filter comp (DPF), measure the depth
of ash (depth of remaining ash) with a pin gauge at positions
shown in the figure.

f
138 mm (5.43 in.)
g
226 mm (8.90 in.)
2. If the depth of ash (depth of remaining ash) is out of the
allowable limit, the filter comp (DPF) cannot be reused.
If the filter comp (DPF) is judged as non-reusable, report the
result of the Judgment to the customer that requested the filter
cleaning via the service dealer, and replace the filter comp
(DPF) with a new one.
NOTE
• Select a metal pin gauge having a wire size slightly thinner
than the cell width (0.5 to 1.0 mm dia., 0.020 to
0.039 in. dia.).
• When the pin gauge is inserted into the cell hole, insert it
by lightly tapping on the gauge end with a finger tip.
The insertion depth of the pin gauge must not exceed
140 mm (5.51 in.).
If the pin gauge is forcibly pushed in, the pin pierces
through the deposited ash and it cannot be measured
accurately. So use caution not to push the pin forcibly.

and clean, soft water in the specified mixing ratio.
• The anti-freeze absorbs moisture. Keep new anti-freeze in
a tightly sealed container.
• Do not use the radiator cleaning agents after you add
anti-freeze to the coolant. Anti-freeze contains an
anti-corrosive agent, which reacts with the radiator
cleaning agent to make sludge and cause damages to the
engine parts.

1. ENGINE
[1] CYLINDER BLOCK
The engine utilizes a split crankcase to produce
greater durability and operate more quietly; the
crankcase is split into two parts, crankcase 1 (1), which
houses the parts for combustion and crankcase 2 (2),
which completes crankcase 1 and produces low-noise.
It uses a hanger type of crankshaft support which
allows for easy dis/assembly and the lining of the
cylinder is a linerless type, which offers good cooling
performance and excellent resistance to wear as it is
little affected by distortion.

[2] CYLINDER HEAD
We have improved the helical shaped 2-valve,
2-stage ports in order to generate an ideal swirl and
intake air inertia at the intake port and to gain a greater
amount of air for the air/fuel mixture.

2. LUBRICATING SYSTEM
[1] OIL COOLER
The engine is equipped with a water-cooled oil
cooler to keep the temperature of the oil from rising while
the engine is running and provide it with proper
lubrication.
The oil flows on the inside of the cooler plate and is
cooled by the coolant flowing on the outside of the plate.

3. COOLING SYSTEM
[1] THERMOSTAT
This thermostat uses a wax-pellet type. When
temperature goes up, wax in metal container (pellet)
changes to a liquid from a solid.
The volume starts to expand in this process. As
spindle is fixed, pellet goes down and valve goes down.
There is a jiggle valve on the top depending on the
specification.
When you put coolant and thermostat is closed,
coolant can not go in easily because air at the engine
side can not go out.
The jiggle valve helps to remove air from this hole,
and then coolant can go in easily.

[2] BOTTOM BYPASS SYSTEM
In addition to improving the cooling performance of
the radiator by utilizing a bottom bypass system, the
mechanism utilizes a 3-stage thermostat valve that
reduces thermal shock considerably compared to
previous radiators.
When the coolant inside the engine is cool, the
thermostat (1) stays closed and coolant circulates inside
the engine via the bypass pipe.
When the temperature of the coolant exceeds the
opening temperature of the thermostat (1), the
thermostat opens in three stages, sending the now hot
coolant to the radiator. Further, when the thermostat is
fully open, it is structured so the hot coolant does not flow
into the engine via the bypass circuit, thus increasing the
cooling performance of the system.

system not only complies with strict emission regulations, it enables multiple, precise high-pressure injections that do
not vary with engine RPM.
The system is an electronically controlled fuel injection device, with a supply pump (3) that pressurizes the fuel,
a rail (2) that stores the high-pressure fuel, injectors (1) that inject the fuel under high-pressure via solenoids into each
cylinder and an engine ECU that controls them all.
Various parameters are controlled by the engine ECU, such as the amount of fuel from the injectors and their
timing, the pressure of fuel in the rail, etc., as sensed via signals from each sensor and CAN communications from
the engine's ECU.
This results in fuel always being injected under ideal conditions, which suppresses the hallmark of a diesel engine,
the black smoke during takeoff and acceleration, so there is less smoke, it is cleaner and with a higher output of
power.

[2] SUPPLY PUMP
The supply pump is equivalent to previously used
injection pumps and it delivers fuel to the rail at a
pressure more than double that of previous pumps.
It consists of a feed pump (10), regulating valve (6),
SCV (suction control valve) (2), pump unit, delivery valve
(3) and a fuel temperature sensor (1).

Feed Pump
The feed pump sucks up fuel filtered by the fuel filter
and supplies it to the pump unit.
The feed pump is a trochoid pump with an inner rotor
and outer rotor (1) geared elliptically; the inner rotor (3)
is driven by the drive shaft (2) and drives the outer rotor
in turn in the same direction. In the process, the volume
of the part enclosed by the teeth of the rotor changes and
thus pumps the fuel.

Regulating Valve
The regulating valve controls the fuel feed pressure
(feed pump discharge pressure) so it always stays at the
set pressure.
When the feed pressure exceeds the set pressure
due to changes in the pump's RPM, the piston (4)
overcomes the pressure of the spring, opening the valve
and returning fuel to the suction side of the feed pump
(2).

By regulating the amount of fuel supplied to the plunger (4), the SCV (8) controls the pressure of fuel in the rail.
The SCV uses a linear solenoid valve and the fuel flow is controlled by controlling how long the SCV is energized by
the ECU.
There are two types of SCV valve, the fail-open type (max flow with no power) and the fail-closed type (min flow
with no power) and the engine uses a fail-open SCV.
When power flows to the SCV (8), the actuator inside moves according to the duty ratio, pressing on the cylinder
(7) and altering the flow of fuel corresponding to the size of the cylinder opening and establishing the appropriate
amount.
1) Fail-open type
With no power to the solenoid, the cylinder is returned via spring force and the valve opens wide, supplying a large
quantity of fuel to the plunger.
When the solenoid is energized, the armature presses on the cylinder, compressing the spring and reducing the
quantity of fuel supplied. The solenoid turns ON & OFF according to the duty ratio. The quantity of fuel supplied to
the plunger is in proportion to the size of the cylinder opening.
2) Duty ratio control
The engine's ECU outputs a waveform signal for a set interval. The current amperage is the average amperage
of the average current differential. When this average value rises, the size of the valve opening is reduced, and
conversely, when it drops, the valve opens wider.
3) When the SCV operates for a short time
The average current to the solenoid is low, so the cylinder is returned via spring force and the valve opens wide,
supplying a large quantity of fuel to the plunger.
4) When the SCV operates for a long time
The average current to the solenoid is high, so the armature presses on the cylinder, compressing the spring,
closing the valve opening and supplying a smaller quantity of fuel to the plunger.

Pump Unit
The pump unit works to increase the pressure of fuel
received from the SCV and is composed of a drive shaft
(1), ring cam (3) and two plungers (5). A ring cam (3) is
mounted on the outside of the eccentric cam (2), which
is on the same axle as the drive shaft; the plungers are
arranged symmetrically vertically on the ring cam.
When the drive shaft rotates, the eccentric cam
rotates eccentrically and the ring cam (3) is driven up
and down by it, which operates the two plungers (5)
through their cycles.

Delivery Valve
The delivery valve is integrated with the element (1)
and is composed of a check ball (2), spring (3) and
holder (4).
When the pressure on the plunger side (5)
equals/exceeds the pressure on the rail side, the check
ball opens and discharges fuel. As soon as the fuel
pressure feed is complete, the check ball is pressed
back by the spring and when it touches the seat of the
element, it cuts off the rail side from the plunger side,
thus preventing any backflow of fuel.

Fuel Temperature Sensor
The fuel temperature sensor is mounted on the fuel
intake side and detects the temperature of the fuel using
the characteristic of the thermistor (1), whose electrical
conductivity varies with temperature.
Please note that the fuel temperature sensor is not
treated as a part, so replacing it requires replacement of
the supply pump.

[3] RAIL
The rail (2) stores fuel at the high pressure applied
by the supply pump and supplies the shared pressure to
the injectors of each cylinder. The rail incorporates
control parts-a rail pressure sensor (3) and a pressure
limiter (1).
The pressure of the fuel in the rail is detected by the
rail pressure sensor, and optimal feedback control is
provided for the engine RPM and load. This greatly
improves the ability to raise the pressure at low RPMs
and enables high-pressure injection from low speed
ranges.
Pressure Limiter
The pressure limiter operates when the pressure
inside the rail becomes excessively high (valve opens),
and then once the pressure drops to a certain pressure,
it acts to maintain the pressure (valve closes).
Fuel discharged by the pressure limiter returns to the
fuel tank.

sensor, which uses the piezo resistance effect, in which
increasing the pressure on its silicon element changes
its electrical resistance. Please note that the rail
pressure sensor is not treated as a part, so replacement
requires replacing the rail assembly.

[4] INJECTOR
The injectors inject high-pressure fuel from the rail
into the combustion chamber of the engine, using
signals from the engine's ECU to produce the ideal
timing, amount of fuel, mixture and spray.
The injector injects a finely tuned spray in three
pulses during the combustion stage. First a small
amount is injected, mitigating the effect of the initial burn
and reducing NOx (oxides of nitrogen) and noise. The
main injection follows with the real burn, and in the last
stage, a diffuse combustion is induced, thus reducing
particulate matter (PM) generated by the main injection.
Injector Architecture
Injectors consist of nozzle components (nozzle (10)
and needle valve (9)), a TWV (two-way valve) (5), which
controls the volume and mixture of fuel, a control
chamber (7) with an intake orifice and discharge orifice
(6), a command piston (8) and a nozzle spring.

From Rail
To Fuel Tank
The injector uses the signal output from the engine ECU to control the injection with the fuel pressure in the control
chamber.
The system for controlling the pressure of the control chamber works by energizing the solenoid, which opens the
passage of the chamber's discharge orifice and the fuel is injected due to the drop in pressure. When the current
stops, the pressure in the control chamber returns to what it was and injection ceases.
1) Injection Stop
With no current to the solenoid (1), the TWV (2) cuts off the discharge orifice (3) passage, so rail pressure is
applied to the control chamber (8) and the bottom of the needle valve (5). As the diameter of the command piston (4)
on the control chamber side is larger than the diameter of the bottom of the needle valve, it works to push the needle
valve down, which is compounded by the nozzle spring pushing it down, and the needle valve is closed.
2) Injection Start
When the solenoid (1) is energized, it draws the TWV (2) up, opening the passage of the discharge orifice (3),
returning fuel in the control chamber (8) to the fuel tank via the leak passage (6) and dropping the pressure.
The drop in the pressure of the control chamber causes the pressure applied to the bottom of the needle valve
(5) to become greater than the pressure on the control chamber side, and the needle valve compresses the nozzle
spring and starts injecting fuel.
3) Injection Finish
When current to the solenoid (1) stops, the TWV (2) lowers and the discharge orifice (3) passage is closed.
When the passage of the discharge orifice closes, the fuel pressure in the control chamber (8) recovers to the rail
pressure, so the needle valve (5) is pressed back via the command piston (4), stopping the injection.
9Y1210651ENM0017US0
Injector Drive Circuit
To increase the responsiveness of the injector, the
voltage that drives the injector is raised to a high voltage,
accelerating the magnetization of the solenoid and
increasing the responsiveness of the TWV.
The battery voltage is raised to about 110 V by a
high-voltage generating circuit inside the ECU and that
voltage is supplied to the injector to actuate it.

Injector QR/ID Codes
Injectors are processed to exacting tolerances, but
there are minute variations in the amount they inject, so
to correct for these variations, a correction volume is
recorded on the QR/ID codes of the injectors.
During manufacture, the QR code is read by a
scanner and the correction value is registered in the
ECU.

(1) Engine ECU
The engine ECU (1) controls the amount, timing,
mixture and pressure of fuel that is injected. The engine
ECU (1) operates each kind of control based on the
signals from each type of sensor.
The actuator for controlling the amount, timing and
mixture of fuel injection is the injector, while the actuator
for controlling fuel pressure is the supply pump.
Q Fuel Quantity Control
The amount of fuel to be injected is determined using
a basic injection amount, which is calculated based on
the state of the engine and driving conditions, with
corrections added for parameters such as water
temperature, fuel temperature, intake air temperature,
intake pressure, etc.
Q Injection Timing Control
The ECU controls the timing for starting to energize
the injectors, first determining the timing for the main
injection and then setting the timing of other injections,
such as pilot injections.
Q Fuel Mixture Control
By conducting a pilot injection, the initial fuel mixture
is kept to a minimum, mitigating the explosive initial
combustion and reducing NOx and noise.
Q Fuel Pressure Control
The ECU calculates the set fuel injection pressure
based on the engine load (last injection amount and
engine RPM) and controls the amount the supply pump
supplies and the fuel pressure inside the rail.

Crankshaft Position Sensor
The crankshaft position sensor (2) is mounted near
the crankshaft gear of the gear case (1) and the sensor
utilizes an MRE (magnetic resistance element) type of
sensor.
When the crankshaft pulsar gear passes by the
sensor, it alters the magnetic field inside the sensor,
generating an AC voltage, which is output to the engine
ECU.
Further, the gear has a wide part between teeth,
which alters the waveform of the AC voltage and the
sensor detects the crankshaft position with every
revolution; this change in the voltage is amplified by the
IC circuit inside the sensor and outputs it to the engine
ECU.
The engine ECU uses the signals to calculate the
piston position and engine RPM.

This is a device that regulates EGR gas flow. The
degree the valve is open is detected using a lift sensor

Also, passing engine coolant through the housing
enables controlling temperature rise of the EGR valve.

CAUTION
• To prevent an accidental short circuit, attach the positive cable to the positive terminal before the
negative cable is attached to the negative terminal.
• Do not remove the battery cap while the engine operates.
• Keep electrolyte away from eyes, hands and clothes. If you are spattered with it, clean with water
immediately.
• Keep open sparks and flames away from the battery at all times. Hydrogen gas mixed with oxygen
becomes very explosive.
IMPORTANT
• Do not disconnect or remove the battery when you operate engine.
9Y1210651ENS0017US0
Battery Voltage
1. Stop the engine.
2. Measure the voltage with a circuit tester between the battery
terminals.

Battery Specific Gravity
1. Measure the specific gravity of the electrolyte in each cell with a
battery and coolant tester.
2. If the electrolyte temperature is different from the one that the
battery and coolant tester calibrated, correct the specific gravity
measurement. Use the formula below in (Reference).
3. If the specific gravity is less than 1.215 (after it is corrected for
temperature), charge or replace the battery.
4. If the specific gravity is different between 2 cells by more than
0.05, replace the battery.
(Reference)
• The specific gravity changes with temperature.
To be accurate, the specific gravity
decreases by 0.0007 when temperature increases by 1 °C
(decreases by 0.0004 when temperature increases by 1 °F),
increases by 0.0007 when temperature decreases by 1 °C
(increases by 0.0004 when temperature decreases by 1 °F).
Thus, if you refer to 20 °C (68 °F), correct the specific gravity
reading by the formula below:
– Specific gravity at 20 °C = Measured value + 0.0007 ×
(electrolyte temperature −20 °C)
– Specific gravity at 68 °F = Measured value + 0.0004 ×
(electrolyte temperature −68 °F)

9. Connect the engine harness and the main switch.
10. Connect the battery.
11. Attach a tester (10) to the output terminal (13) and ground
terminal (12) of the crankshaft position sensor (11).
12. Turn the main switch "ON".
13. Turn the flywheel and make sure that the voltage of the
crankshaft position sensor goes from 0 → 5 V or 5 → 0 V.
14. Rotate the flywheel and align the crankshaft position sensor to
the part of the pulsar gear (14) that is missing teeth (16).
15. The 14th tooth (15) from the missing teeth is the standard.
16. Slowly turn the flywheel counterclockwise and stop the flywheel
at the point where the needle of the tester changes momentarily
from 0 → 5 V, the 14th tooth.
17. That point is where the crankshaft position sensor detects TDC.
18. Set the tri-square (6) on the reference line (9) on the flywheel
housing side and mark the detection point of crankshaft position
sensor TDC (18) on the flywheel.
19. Measure the interval (19) between the crankshaft TDC (17) and
the detection point of crankshaft position sensor TDC (18).
20. Calculation of fuel injection timing correction 1.0 mm (0.039 in.):
0.342 ° Corrected angle = 0.342 ° X actual interval
21. Overwrite the injection timing correction value in the ECU.
IMPORTANT
• When the crankshaft position sensor detects the teeth of
the pulsar gear, the tester indicates 0 V.
• The position where the needle of the tester changes
momentarily from 0 → 5 V is the detection point of
crankshaft position sensor TDC (18).
• The reference line indicates the crankshaft TDC (17) of the
crankshaft. If the detected TDC is ahead of the crankshaft
TDC, it is considered minus. If the detected TDC lags
behind the crankshaft TDC, it is considered plus.
