加机油。对静止的发动机，由加油口向油底壳内加机油。直到油面达到油尺的上方标记。然后
用手压泵向管路系统和各润点供油至油压在 0.05MPa 以上。（带电动预供油泵的机型在开车前自
行供油）。
Add engine oil. Add engine oil to your engine at stop state through oil filler into oil sump until oil level
reaches the upper mark of dipstick. After that, prime oil with hand pump to pipeline system and various
lubricating points (oil pressure: ≥0.05MPa). For engine with electric primary pump, the oil is supplied
automatically by the pump before starting.

气泡为止，然后旋紧。
Fill the self-provided fuel tank with specified and clean fuel and supply fuel to fuel system with hand
pump. Screw off the air release screw plug on the top of fuel filter, the release screws on the top of

采用电力起动时，应先向起动蓄电池充电，保证蓄电池电压不低于 24V。
For the electric started engine, charge the battery firstly, and the voltage should not be less than 24V.
6．柴油机的起动
Engine Start
采用气马达起动时
Start with pneumatic motor:
将开车把手置于开车位置，首先旋开起动空气瓶上的控制小阀和中央大阀，然后再打开气马
达的开关阀，柴油机将能立即起动。起动后应立即关闭气马达的开关阀，并立即将空气瓶上各阀依
次关闭。
Open the control valve and central gate valve on starting air bottle, then open the switch valve of
pneumatic motor and the engine will be started immediately. Close the switch valve of the motor
immediately after the engine is started, and then close all valves on the air bottle.
如果气马达齿轮未旋出，关闭阀门，检查气马达；如果飞轮转动，但在三秒内未能起动，应立
即关闭阀门，停止喷油，并查找原因。
If the gear of pneumatic motor is not screw out, close the valve and check the motor. If the engine is not
started in 3s with the flywheel rotating, close the valves immediately and stop injecting and find out the
reason.
采用电马达起动时
Start with electric motor:
将开车把手置于开车位置，首先接通蓄电池开关，插入电路钥匙打开，然后按下起动按钮，柴
油机应能立即起动，起动后，应立即释放按钮，使起动电路迅速断开，并关闭电钥匙，断开开关。
起动时间不能大于 5 秒，若一次未能起动，再起动时应停 2 分钟。
Set up the start handle at the starting position. Turn on battery switch, insert the electric circuit key, press
start button, the engine should be started. After the engine is started, release the button immediately to
open the starting circuit and close the key switch. The starting time should not be more than 5 seconds. If
your engine can’t be started at one time, wait at least 2 minutes before trying again.

R660系列柴油机维修保养手册

Maintenace Manual For R660 Series Diesel Engine
带电动预供油泵的机型在起动时，电动预供油泵会向柴油机管路内充油，至规定压力后再接
通电马达回路起动柴油机。这个过程在柴油机首次起动时会持续 30 ～ 60 秒。所以首次起动时间
较长，属正常现象。
For the engine with electric prime pump, the prime pump will fill oil to the pipeline when starting (when
first starting of engine, it is about 30-60s), and switch on the electric motor to start the engine when the
specified fuel pressure is reached.
7．柴油机的运转
Engine Running
柴油机全负荷运转后，应先卸去负荷，逐渐降至怠速，待水温降至 60℃以下时再停车。严禁在
水温过高时骤然停车。凡是突然停机，应立即盘车 3 ～ 5 圈，避免活塞与缸套之间出现抱缸现象。
If your engine runs with full load, unload it and reduce speed gradually down to idle speed, do not
shutdown your engine until water cools down to below 60℃. Never shutdown your engine abruptly when
water temperature is too high. If the engine is stopped suddenly, rotate the crankshaft of the engine about
3-5 revolutions to avoid piston seizure.
经常注意机油压力和循环水温度，以免因控制系统失灵而造成事故。
Constantly pay attention to oil pressure and circulating water temperature so as not to cause any accident
due to control system failure.
经常注意油耗变化和排气烟色，以鉴别喷油器的工作性能和使用负荷的变化情况。
Constantly pay attention to variation of fuel consumption and exhaust smoke color to verify performance
of fuel injector and applied load.
注意柴油机在正常负荷下工作，避免柴油机超负荷工作。
Make sure that your engine runs with normal load. Never overload operation.
在寒冷季节（气温 0℃以下）停车后，应将冷却水放尽，以免冻裂柴油机机体、气缸盖等零部件。
放水应在停车半小时后进行，切不可停车后立即放水，否则，各摩擦表面温度很高，会将其间储存
的少量机油蒸发掉，造成再起动困难及不正常磨损，甚至能使活塞胀死在气缸内。
In cold season (air temperature below 0℃), drain cooling water completely to prevent frost crack of
engine block and cylinder head 30 minutes after shutdown. Never drain cooling water immediately after
shutdown, or the oil on the friction surfaces will be transpired and cause difficult starting and abnormal
wear.
注意：柴油机停车后，不得立即打开热交换器加水盖，以免被水蒸气灼伤。
Caution: Do not open water filler cap of heat exchanger immediately after the engine is
shutdown, so as to prevent being burned by hot vapor.

使用盘车杆慢慢转动柴油机飞轮，使机后盖上的箭头对准飞轮上的“1-6”凹痕标记，此时柴
油机第一缸活塞处于上止点位置，第一缸的进排气门处于关闭状态（若第一缸的进排气门此时处
于开启状态，应继续盘动飞轮一周，使指针再次对准“1-6”凹痕标记，以便使第一缸的进排气门处
于关闭状态
Turn the flywheel with a bar and make the arrow pointer on the rear cover of the engine aligning with the
“1-6” mark on the flywheel housing. The piston of 1st cylinder is at TDC and the inlet/outlet valves
are closed at this time (if the inlet/outlet valves are open, turn the flywheel right along, and make the
pointer aligning with the “1-6” mark again to close the inlet/outlet valves of the 1st cylinder).

Maintenace Manual For R660 Series Diesel Engine
用塞尺检查气门间隙
Check valve clearance with feeler
gauge.
进气门间隙：（0.4±0.05）mm
Inlet valve clearance: (0.4 ±0.05) mm
排气门间隙：（0.5±0.05）mm
Outlet valve clearance : ( 0.5 ±0.05)
mm
注意：检测气门间隙时，柴油机应
处于冷态——低于 60℃，塞尺在气门桥
和摇臂间滑动，有阻滞发粘感觉时，所测
间隙为准确值。
Caution: Valve clearance shall be
measured with engine at cold state, i.e.,
temperature less than 60℃ . The measured
clearance is an exact value if a slight
resistance is felt when feeler gauge is
sliding between air valve bridge and rocker
arm.
第一缸活塞位于压缩冲程上止点位
置。
The piston of cylinder No.1 is at TDC
position of compression stroke.
如右表所示检查或调整气门间隙。
Check or adjust valve clearance as per
Table below.
