1.山东装载机 http://www.sdyongbaojixie.com/点火提前对发动机是有一定影响的。点火提前较小，可直接影响发动机动力，一般表现在动力不足，出现山东装载机爬坡无力，举升速度慢等情况。The ignition of the Shandong loader has some influence on the engine. Ignition ahead of the smaller, can directly affect the engine power, the general performance of the power shortage, the emergence of Shandong loader climbing weakness, lifting speed and so on.

2.点火提前较大，对发动机有较大不利影响，分别表现为：山东装载机燃油消耗率变大，很费油；如果太提前，当发动机活塞运动到上止点时，缸内燃烧已经开始对发动机活塞有向下的气压，造成活塞做功效率降低，时间长了，很可能会有敲缸现象出现。长时间使用会对发动机造成严重损伤，影响山东装载机发动机寿命。The ignition is large, there is a greater adverse impact on the engine performance for Shandong loader fuel consumption rate becomes large, very expensive oil; if it is too early, when the piston engine to the TDC, the combustion has begun a downward pressure on the engine piston, causing the piston work efficiency reduced, a long time that is likely to appear knock phenomenon. Long time use can cause serious damage to the engine, which affects the life of the Shandong loader engine.

3.点火推迟：对发动机，造成山东装载机动力输出较慢，表现在动力不足上，但对发动机本身损伤相对较小。Ignition delay: on the engine, resulting in the slow loading of the motor load in Shandong, the performance of the lack of power, but the damage to the engine itself is relatively small.
