1.2 新柴油机使用须知
Operating notice for new diesel engine
●工程机械及拖拉机用柴油机，在最初使用的 60h 内，柴油机应在部分负荷（油门在 3/4 位置
以下）工作。
During the first 60h, the speed of diesel engine for construction machinery and tactor is limited to
work at partial load (fuel throttle is at 3/4 positon).
●汽车用柴油机，在汽车使用的最初 2000Km（约 60h）内应限制柴油机转速不超过标定转速
的 80%。
During the first 2000km (about 60h), the speed of diesel engine for vehicle is limited to not exceed
80% of the rated speed.
●新机经初期使用磨合后，需要更换机油，否则可能造成柴油机零件的过度磨损或损坏。正确
地维护保养将使您的柴油机有更好的性能、更经济的运转及更长的寿命。
After a running-in period in the first use, the oil in new diesel engine should be replaced. If not, the
parts of diesel engine could be worn out or damaged. The correct maintenance will make diesel engine
better in performance, more economic running and longer in service life.
●每日检查油压表、温度表、报警指示灯和其它仪表，确保它们正常使用。
Oil-pressure gauge, temperature gauge, warning indicating lights and other instruments shall be
checked every day for their normal function.
●按说明书中要求进行日常维护和保养。
Daily inspection and maintenance should be done according to this instruction.
1.3 柴油机的启封
Unsealing Diesel Engine
当您打开您的柴油机包装箱之后，首先按文件清点柴油机及随机附件，检查柴油机外表有无
损伤，然后进行下述工作：
After you have unpacked your diesel engine, firstly you should check diesel engine and the
accessories with it and inspect if diesel engine is damaged, and then you begin to do the followings:
●擦拭外露件的防锈层、防蚀剂等。
Clean the antirust coat and anti-corrosive agent on parts close to the air.
●放出燃油滤清器及燃油系统零件内部油封油（也允许燃油系统的油封油不经放出而启动，
但必须等燃油系统油封油消耗完正常柴油机已供应到才允许发动机满负荷运行）。
Drain off the oil in oil seals inside fuel filter and parts in fuel system (Start-up is also permitted
without draining off the oil-seal’s oil in fuel system, but diesel engine may not run under full load until
the oil-seal’s oil is used up and normally replenished by diesel engine).
●转动飞轮并向进气管内喷溶剂到驱尽油封油为止。
Turn the flywheel and spray in the air inlet valve with solvent until the oil-seal’s oil is driven out.

●向增压器排气口喷溶剂，直到驱尽油封油为止。
Spray in the exhaust port of turbocharger with solvent until the oil-seal’s oil is driven out.
●根据厂方与用户的协议，对油底内未注油的应按规定注油。
According to the agreement between the manufacturer and the user, fill oil in the empty oil sump as
per specifications.
●按厂方与用户的协议，出厂用户需要，已加注满冷却液的应检查冷却液的性能，如果防冻能
力满足 -30℃或 -35℃时，其 PH 值为 7-8（中性），总硬度值为 5-15° d[9-27° f（硬度）] 则可以
使用这些冷却液，如不合乎要求，则应放出，重新加注含防冻剂的冷却液。
According to the agreement between the manufacturer and the user, check the performance of
coolant that has been filled up, if needed. The usable coolant must be under the conditions of temperature
-30℃ or -50℃ , pH value 7-8 (neutral), general hardness value 5-15° d[9-27° f (hardness)]. If the
coolant cannot meet the above-mentioned requirements, drain off it and add new coolant with anti-
freezing agent.
1.4 柴油机的安装就位
Mounting and Positioning of Diesel Engine
●柴油机的起吊、安装、就位调整按柴油机使用说明书的要求进行。
Hoisting, mounting and positioning of diesel engine shall be done in accordance with diesel engine
operation manual.
1.5 起动前的准备工作
Preparation before Start-up
●加冷却液
Add coolant
●加机油

1.6柴油机的起动
Start-up of Diesel Engine
●将电源开关、电钥匙处于起动位置。
Put the power switch and key in the starting position.
●变速杆处于空档位置。
Place the gear shift lever in the neutral position.
●踩下离合器踏板和油门踏板，然后拉动过量燃油装置的拉手开关（若装有此装的话），并操
纵起动机，当发动机起动后应将过量燃油装置的拉手开关复位，若发动机起动不了，则待约 1 分钟
后再重复上述操作，发动机起动后，机油压力表应立即显示压力，起动热发动机时，可不必使用过

量燃油装置。
Step on the clutch pedal and accelerator pedal, then pull the handle of excessive fuel device (if
available), and operate the starter. After start-up of diesel engine, return the handle of excessive fuel
device to its original position. If diesel engine cannot be started, wait for about one minute and repeat the
above operation. The pressure value is shown at once on the oil manometer after start-up of the engine.
In heat starting of the engine, it is unnecessary to use the excessive fuel device.

装有电子控制火焰预热起动装置
Flame-preheat starting device with electronic control
发动机水温低于 -23℃时，打开钥匙开关预热指示灯亮，电热塞通电加热，经 50s 后预热指示
灯自动闪烁。电热塞已加热到 850-950℃，按下起动按钮，接通起动机，电磁阀自动打开油路，给
电热塞供油，进行火焰预热起动，可使发动机在 -25℃下顺利起动。
When the water temperature of the engine is below -23℃ , open the key switch and the preheating
indicating light is on lighting, the electro-heat plug is heated through electricity, and for 50 seconds,
the preheat indicating light twinkles automatically. After the electro-heat plug has been heated to

1.7 柴油机的运转
Running of Diesel Engine
◆ 柴油机在低于最大扭矩的转速下，全油门持续运转不超过 1 min。
When the engine running at the speed lower than the speed of the biggest torque，it is not allowed to
continue running on full load over l min．
◆柴油机全负荷运转后，停车前要怠速运转 3-5 min。
After running on full load，the engine should run in idling speed for 3—5 minutes before stopped．
◆经常注视油压表及冷却液温度表：若压力和温度不符合规定要求时应该将柴油机停车。
Often watch and check the oil pressure gauge and coolant temperature meter．Stop the engine if the
pressure and temperature cannot meet the standard requirement．
注意：在冷却液温度低于60℃或高于100℃时连续运转将有损于发动机。
Note：Diesel engine can not continue to run when the coolant temperature is lower than 60℃
or higher than 100℃，because this would damage the engine．
◆柴油机的停止
Engine's running stop
拉动喷油泵手油门置于零位，操作排气制动器，停止发动机，重新调整手油门。
The oil pressure gauge and the coolant thermometer shall often be watched. If the pressure and
temperature do not conform to the specified values, diesel engine should be stopped.
注意：发动机在停止之前以怠速运转1-2min后再停车。
Note：The engine should run in idling speed for 1-2 minutes before stopped．
