Engine
D13A440, EU4SCR / EU5SCR
Fact Sheet
The D13A440 is a 440 hp 12.8-litre in-line, six-cylinder
diesel engine equipped with an overhead camshaft, four
valves per cylinder and unit injectors. The engine meets
the EU exhaust emissions requirements according to Euro
4 and Euro 5 (incentive) standards.
The D13A440 is designed for heavy long-haul and
construction operations. It is based on a robust and
dependable design with an overhead camshaft, four valves per
cylinder and precisely controlled electronic fuel injection.
The engine is designed for low fuel consumption, good driving
properties and high availability. The timing mechanism
is located at the rear of the engine, which results in less
vibration and permits the fitting of a rear-mounted power
take-off.
The D13A440 is a low-emission engine as regards both
exhaust gases and noise level. Owing to after-treatment of
exhaust emissions with SCR (Selective Catalytic Reduction)
technology, the engine is approved to the EU’s Euro 4 and
Euro 5 (incentive) standards.
The D13A440 is available with VEB+ (Volvo Engine Brake)
as an option. This system provides extremely high braking
effect, further improving safety and reducing wear on the
wheel brakes.
The D13A440 is characterised by the following product
features:
• Maximum torque within a broad rev range.
• Fuel-efficient.
• Electronic engine management (EMS).
• Low-emission variants, Euro 4 and Euro 5 (incentive)
• Extremely high engine braking effect with VEB+ (option).
• Rear-mounted power take-off with high power output
(option).
• Closed crankcase ventilation (option).

Fact Sheet
Efficient combustion for
excellent driveability
The D13A is equipped with unit
injectors that provide high injection
pressure. The combustion chamber
and inlet manifold are designed for
optimum combustion. The gas-fill ratio
is extremely high, which contributes to
the high efficiency.
This design creates a fuel-efficient
engine with high power and immense
torque within a broad rev range. This
gives the D13A excellent driveability.
Meets emissions requirements
with SCR technology
In order to supplement optimum
combustion technique the exhaust gases
are after-treated by SCR technology
(Selective Catalytic Reduction).
In this process, an additive (AdBlue) is
injected into the exhaust gases before
they pass through an SCR catalytic
converter. There the AdBlue reacts with
the nitrogen oxides in a process that
significantly reduces emissions.
With this system, the D13A is approved
to EU emissions standards according to
Euro 4 and Euro 5 (incentive).
AdBlue tank located beside the regular diesel
tank.
Vibration damper cuts
noise emissions
The D13A meets the relevant noise
emission requirements without needing
advanced encapsulation. The crankshaft
and camshaft feature hydraulic vibration
dampers which minimise noise and
vibrations. The electronic injection is
also used to further dampen noise at
low revs. This makes the D13A a quiet
engine which idles very softly.
Closed crankcase ventilation
The D13A is available with optional
close crankcase ventilation. The system
is known as CCV-C (Crank Case
Ventilation – Closed). The crankcase
gases in the valve cover are returned
to the turbocharger via an oil separator
with a centrifuge. The oil mist is
separated in the maintenance-free
centrifuge system, so there is no need
for filter replacements.
Owing to the recycled crankcase gases,
this system promotes an extremely
clean and environmentally compatible
engine.
VEB+ engine brake provides
extremely high braking effect
The D13A is available with the VEB+
(Volvo Engine Brake+) auxiliary brake.
Its design is based on interaction
between the exhaust brake governor and
Volvo’s patented compression brake.
Using a specially designed camshaft in
combination with rocker arms, the gas
pressure in the cylinders is regulated to
provide maximum braking power.
VEB+ provides extremely high braking
effect – up to 375 kW. A powerful
engine brake boosts safety at the same
time as wheel brake wear is reduced. In
combination with cruise control, VEB+
creates the necessary preconditions for
higher average speed and better fuel
economy.
Electronic engine management
integrated in the vehicle
electronic system
Timing and power take-off
at the rear
The engine timing mechanism is located
at the rear and drives the power steering
pump, oil pump, fuel feed pump and
air compressor. It is a compact, quiet
and thoroughly sealed design that saves
weight. With the timing at the rear, the
engine’s cooling is also improved since
the flow of incoming cooling air is not
obstructed.
The D13A can be equipped with a
power take-off designed for propeller
shaft operation or direct-mounted
hydraulic pumps. PTO mounting
on the engine’s flywheel results in a
dependable design and permits high
torque levels, up to 1000 Nm in
continuous operation.
The D13A engine is equipped with
Volvo EMS (Engine Management
System) which means that the engine’s
functions are operated and controlled
entirely electronically. EMS promotes
efficient engine management and
advanced scope for diagnostics and
fault-tracing.
The engine control unit is connected
to the vehicle electronic system’s data
links and the information is presented
via an easy to read display in the
instrument panel.
