柴油发动机起动困难或起动不着的原因较多,归纳起来一般有以下四个方面:1 起动转速低。其原因有:蓄电池容量不足或接头松弛;起动机炭刷与整流子接触不良;起动机齿轮与飞轮齿圈的中心线不平行,造成齿轮不能嵌入齿圈正常位置进行传动等。2 供油系统不正常。原因有:输油泵不供油或供油不足;喷油压力过低或喷油嘴喷孔堵塞,喷油雾化不良;喷油泵出油阀密

Diesel engine start difficult or start-up for many reasons, summed up in general has the following four aspects: A low starting speed. The reasons are: lack of battery capacity or loose joints; starter brush and commutator poor contact; starter gear and flywheel ring gear center line is not parallel, resulting in gear can not be embedded in the normal position of the ring gear and so on. 2 oil system is not normal. The reasons are: oil pump is not enough oil or fuel supply; injection pressure is too low or injector nozzle plugging, poor spray atomization;
