1.山東裝載機(jī) http://www.jmkey.cn/點(diǎn)火提前對(duì)發(fā)動(dòng)機(jī)是有一定影響的。點(diǎn)火提前較小，可直接影響發(fā)動(dòng)機(jī)動(dòng)力，一般表現(xiàn)在動(dòng)力不足，出現(xiàn)山東裝載機(jī)爬坡無(wú)力，舉升速度慢等情況。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.點(diǎn)火提前較大，對(duì)發(fā)動(dòng)機(jī)有較大不利影響，分別表現(xiàn)為：山東裝載機(jī)燃油消耗率變大，很費(fèi)油；如果太提前，當(dāng)發(fā)動(dòng)機(jī)活塞運(yùn)動(dòng)到上止點(diǎn)時(shí)，缸內(nèi)燃燒已經(jīng)開(kāi)始對(duì)發(fā)動(dòng)機(jī)活塞有向下的氣壓，造成活塞做功效率降低，時(shí)間長(zhǎng)了，很可能會(huì)有敲缸現(xiàn)象出現(xiàn)。長(zhǎng)時(shí)間使用會(huì)對(duì)發(fā)動(dòng)機(jī)造成嚴(yán)重?fù)p傷，影響山東裝載機(jī)發(fā)動(dòng)機(jī)壽命。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.點(diǎn)火推遲：對(duì)發(fā)動(dòng)機(jī)，造成山東裝載機(jī)動(dòng)力輸出較慢，表現(xiàn)在動(dòng)力不足上，但對(duì)發(fā)動(dòng)機(jī)本身?yè)p傷相對(duì)較小。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.
