曲轴在外力作用下开始转动过渡到能启动维持稳定运转的全过程,称为起动。小型柴油机结构简单,功率小,起动省力,一般功率低于15马力多用人力起动,即借助于人力手摇或拉绳直接转动曲轴和飞轮实现起动。小型柴油机人力起动,要做到方便可靠,必须从下列几个方面注意:一、起动前,应先看机油油标是否在上下界线之间,少则加之,多则放之,使其在上下刻度线之间为机油量合适;再看柴油是否够用,并打开柴油开关;水箱里应加足水。二、用手摇把起动时,手应握紧摇把手柄上的套管(如果摇把手柄上无套管应及时配备或更换),左手打减压手柄,待运转速度上来后,松开左手减压柄,右手继续加力摇动,即可起动。无论柴油机是否起动起来,都不要松开右手,以免曲轴反转使摇把飞出伤人;若起动起来后,摇把卡曲轴的一端会自然脱出,另一端摇把手柄被握紧的 Crankshaft under the action of external force to start the transition to the start to maintain a stable operation of the entire process, known as the start. Small diesel engine has the advantages of simple structure, small power, easy starting and labor saving, generally less than 15 horsepower and more manpower starting. That is to say, the crankshaft and the flywheel are directly started by manpower hand crank or pull rope. Small diesel engine manpower to start, to be convenient and reliable, must pay attention to the following aspects: First, before starting, should look at the oil oil standard is between the upper and lower limits, then plus, as many, put it in the upper and lower The scale between the amount of oil for the appropriate; look at the diesel is enough, and open the diesel switch; water tank should add enough water. Second, the hand crank to start, the hand should hold the sleeve handle on the handle (if the handle on the handle without casing should be equipped or replaced), the left hand to reduce the pressure handle, to be running speed up, release Decompression handle left hand, continue to force the right hand shake, you can start. No matter whether the diesel engine is starting up, do not loosen your right hand so as not to cause the crankshaft to reverse so that the crank will fly out of the wounding person. If it starts up, the crankshaft will naturally come out at one end and the handle will be clenched at the other end
