4.1.3 运行
Running
发动机起动之后，依次使发动机在低速和中速下空车暖机，当发动机冷却液温度高于
60
℃ ，
润滑油温度高于
45
℃ 时，才允许带负荷工作。并注意以下各点：
Warm up the vehicle unloaded by running the engine successively at the low and
medium speeds after it is started; it is allowed for the engine to work with loads only when the
engine coolant temperature is higher than 60 and the oil temperature higher than 45 . Pay
℃ ℃
due attention to the following items:
不允许发动机长期在怠速下运转 。
Do not run the engine at the idle speed for a long time.
怠速时润滑油压力不得低于 0.1Mpa 。
The oil pressure shall not be lower than 0.1Mpa during running at an idle speed.
运转期间的润滑油压力、润滑油温度及出水温度应正常 。
The oil pressure & temperature and outlet water temperature should be normal during
running period
如发现有异响和振动，应立即停车检查 。
Stop and check the vehicle immediately if there is any abnormal noise and vibration.
注意油、气、水的密封情况，如有泄漏，应立即消除。
Pay due attention to the sealing conditions of fuel, air and water; in case of any leakage
solution it immediately.
新的发动机或大修后的发动机不允许一开始就以高速、重负荷工作，在最初的 2500 公里或
60
小时之内，应降低功率使用，负荷应不超过
65%
，以保证良好的磨合。
It is forbidden for a new or an overhauled engine to work at high speeds and with heavy
loads at the beginning; for the first 2500km or 60h, run the engine at a decreased power
and with a load of less than 65% to ensure better running-in.
4.1.4 停车
Stopping
发动机应避免急速停车熄火。停车前应低转速运转
3
～
5
分钟，以使发动机冷却下来，然
后加怠速空转
2
～
3
分钟，使各部分得到充分的润滑油，然后停车熄火。
It should be avoided for the engine to stop suddenly. Before stopping run the engine for
3 ～ 5 minutes at a lower speed to cool down the engine, then run the engine at the idle speed
for 2~3 minutes, and only in this case you can stop the engine.
另外应注意在环境气温低于
5
℃ 以下时，如果发动机冷却液不能确保不发生冰冻，应及时
