INITIAL RUNNING
引擎工作前的准备工作
While prolonged bench running is not essential with DJ engines, a short bench run is useful to
familiarize the modeler with the engine’s characteristics and begin the running in process.
虽然长时间的台架磨合对 DJ engines 并不是绝对必要，但是短时间的台架试车可以帮助您更
快熟悉引擎的特性并开始对引擎进行初步的磨合。
First of all select a well ventilated area to run your engine and observe all SAFETY
INSTRUCTIONS AND WARNINGS. The engine should be firmly mounted to a rigid hardwood
mount or metal test mount. The engine mount should be fixed to a rigid workbench. The top
mounting surfaces should be flat and parallel to prevent placing stress on the engine crankcase.
Use hardened steel screws, steel hex nuts, and lock washers to bolt the engine down. The size of
these screws should be the maximum diameter that will pass through the mounting holes. Be sure
there is adequate clearance for the propeller and that there are no loose items around that could be
blown or vibrated into the propeller’s path.
首先选择一个通风良好的地方来运行你的引擎和遵守所有安全指示和警告。该引擎应牢固
安装在一个硬木或金属的测试台架或刚性工作台上。安装架上端安装面应平行平整，以防对
安装在上面的引擎曲轴箱产生压力。使用淬火钢的螺丝，六角螺母，螺栓和垫圈，把引擎固
定牢靠。这些螺钉的尺寸应该是能通过安装孔最大的直径。要确保螺旋桨周围有足够的空间
而且没有容易松动的零件被吹的进入螺旋桨的旋转面。
ENGING ADJUSTMENT
Every DJ engine has been adjusted to average mixture settings which will most likely allow the
engine to start and run in most location. However, as altitudes and barometric pressures very by
location, it’s very likely that the carburetor mixture setting will need to be adjusted to obtain
optimum performance.
每台 DJ 引擎在出厂之前都经过了大致的调整，在一般情况下都可以正常地启动和工作。但
是由于每个用户所处的环境（海拔，大气压）等情况不同，有可能需要对化油器油针进行微
量的调整才可以使引擎的发挥达到最佳。
FUNCTIONS AND ADJUSTMENTS
功能及调整
(1) Choke Lever
阻风门
(2) Throttle Lever
油门
(3) Idle Speed Adjusted Screw
怠速螺丝
(4) Low Speed Mixture Adjusted Screw (L)
低速油针
(5) High Speed Mixture Adjusted Screw (H)
高速油针
ADJUSTMENT: A general starting point is 1.5 turns out of the low speed needle (NO: 4). And
1-1.5 turns out of the high speed needle (NO: 5).
调整方法：低速针一般开 1.5 圈左右（编号：4）。而高速油针一般开 1-1.5圈
Adjusted the high needle to peak rpm .If ever the engine slows or dies while at full throttle, The
high speed mixture is likely to lean.
调整高速油针直到最高转速。如果在全油门下引擎转速下降或熄火，则高速油针可能太小。
Adjusted the low needle until you achieve a smooth idle and a reliable transition to high throttle, if
the engine dies when the throttle is advanced, the mixture is likely too lean. If the engine stumbles
when the throttle is advanced, the mixture is likely too rich.
调整底速油针，直到您实现油门怠速平稳并可靠地过渡到高速。如果引擎在提速时立即熄火，
则底速油针可能太小了。如果引擎在提速时非常迟钝，则底速油针可能太大了。
Caution: Don’t be tempted to run an overly rich mixture. A too rich mixture will only result
in poor engine performance, pre-mature carbon build up, a fouled plug and excessive
exhaust residue. However, a lean mixture will also damage the cylinder piston badly. After
few flights, check the spark plug, it appears to be yellow if mixture had been set properly
注意：不要把化油器油针调的过大，这样会使引擎无法发挥出功率，排出浓烟，并导致积碳
和火花塞失效。然而如果把化油器油针调的过小，就会使汽缸和活塞严重过热和损坏。在经
过了几轮的飞行之后，拆下火花塞目视检查，火花塞电极的颜色是橘黄色的为最佳。
Carburetor can be rotated 180°for use。
化油器可以使用旋转 180 °使用。
Start-up the engine
启动引擎
Step 1: Close the choke and turn on the ignition, advance throttle to full position.
第 1 步：关闭阻风门，打开点火电源，把油门推倒最大位置。
Step 2: briskly flip the prop through compression until the engine fires and then
dies. It may take an few more flips if this is first time to start the engine after
being stored for a long period.
第 2 步：不停快速地拨动螺旋桨通过引擎压缩位置，直到引擎运转起来，然后自然熄火。
如过引擎经过长时间的放置未使用或是第一次发动，那么可能需要多拨动几次螺旋桨。
Step 3: Open the choke and briskly flip the prop through compression, advance the
throttle to very slightly above the idle position, the engine should start in just
a few flips.
第 3 步：打开阻风门，推一点油门，并再次不停快速地拨动螺旋桨通过引擎压缩位置，直
到引擎运转起来进入正常工作状态。
Step 4: Open the choke, advance the throttle to very slightly above the idle position,
turn on ignition and briskly flip the prop through compression.
第 4 步：热车启动时，直接打开阻风门和点火电源，不停快速地拨动螺旋桨通过引擎压缩
位置，直到引擎运转起来进入正常工作状态。
To stop the engine, cut off the air or fuel supply. Never use your hands, fingers, or any other part
of your body to stop the propeller. DO NTO THROW ANYTHING INTO A RUNNING ENGINE
TO STOP IT!
要引擎停止工作，可以切断空气或燃料的供应。千万不要使用你的手，手指，或任何身体的
其他部分停止螺旋桨。不要把把任何东西扔到正在运行的引擎并使引擎停止工作。
