柴油机点火时间不对,会使油耗增加,动力下降,甚至不能工作。为此,柴油机外侧(胶带轮、正时齿轮、飞轮壳、喷油泵传动轴连接盘等)有点火正时标记。但有些机型根本无标记,这里介绍几种经验判定法。 1．通过气门间隙判定柴油机某缸处于压缩行程终止时。该缸即将进入作功行程,此时该缸的进、排气门正好处于关闭状态,即两气 Diesel ignition time wrong, will increase fuel consumption, power decline, or even can not work. To this end, the diesel engine outside (tape wheel, timing gear, flywheel housing, fuel pump drive shaft connection plate, etc.) ignition timing mark. However, some models are not marked at all, here are several ways to determine the experience. 1. Through the valve clearance to determine a cylinder at the end of the compression stroke. The cylinder is about to enter the work trip, then the cylinder into the exhaust valve just in the off state, that is, two gas
