Maintenace Manual For R660 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.
