裝載機(jī)的柴油機(jī)在有負(fù)荷工作時(shí)，排氣冒淡灰色，柴油機(jī)在超載、突然加速、爬坡或大負(fù)荷工作時(shí)，排氣冒黑煙是正常的。但是在空負(fù)荷或小負(fù)荷狀態(tài)下冒黑煙或大負(fù)荷時(shí)冒黑煙過重，則屬不正?，F(xiàn)象，出現(xiàn)這種現(xiàn)象時(shí)

應(yīng)該怎么辦呢？
1、柴油質(zhì)量差，引起霧化不良，以致不能完全燃燒，應(yīng)清洗油箱，更換柴油。
Poor quality diesel fuel, causing poor atomization, that it can not complete combustion, the fuel tank should be cleaned, replace diesel.
2、噴油器霧化不良或有滴油現(xiàn)象，應(yīng)檢修效驗(yàn)噴油器，必要時(shí)更換噴油頭;
Bad injector atomization or drip phenomenon should overhaul efficacy injector, the injector head replacement when necessary;
3、增壓器有故障，引起供氣壓力不足，使柴油機(jī)燃燒不完全，應(yīng)檢修增壓器;
Turbocharger failure, caused by lack of air pressure, so that incomplete combustion engine should overhaul turbocharger;
4、排氣管冒黑煙，同時(shí)機(jī)器振動(dòng)嚴(yán)重，為個(gè)別氣缸供油太多，可用“斷缸法”予以檢查排除;
Exhaust black smoke, while severe vibration machine for the individual cylinder fuel too, can be "broken cylinder Law" be examined to exclude;
5、排氣管冒黑煙，同時(shí)氣缸內(nèi)伴有清脆的敲擊聲，工作粗暴。出現(xiàn)這種現(xiàn)象一般是供油時(shí)間過早引起的。供油時(shí)間過早，通常還會(huì)引起起動(dòng)困難；排氣管冒黑煙，同時(shí)消聲器內(nèi)有火焰，聲音沉悶。出現(xiàn)這種現(xiàn)象則為供油時(shí)

間過晚所致。供油時(shí)間過晚，常引起柴油機(jī)過熱，排溫升高，甚至可能燒壞機(jī)件。
Exhaust black smoke, accompanied by crisp percussion in the cylinder, work rude. This phenomenon is generally caused by the oil too early. Oil too early, usually also cause starting difficulties;

exhaust black smoke, flames while the muffler, sounds boring. This phenomenon was caused by the oil too late. Oil too late, often caused by overheating engine, exhaust temperature rise, and may

even burn parts.
6、空氣濾清器堵塞，引起氣缸充氣不足，應(yīng)清理或更換空氣濾清器濾芯;
Air filter clogged, causing the cylinder underinflated, you should clean or replace the air filter.
