Many machines can use the color of smoke to identify whether the equipment is faulty, so why does the engine of mine loader smoke?

黑煙是燃燒室內(nèi)燃料不完全燃燒的跡象。缸套和活塞環(huán)的磨損會導(dǎo)致不充分的壓縮壓力，這通常會改變氣缸壓縮沖程在所述混合比的端部，由此在厭氧條件下的碳的燃料和燃燒。它不滴或噴霧噴射器，因此，燃料不能完全與在汽缸中的空氣混合。

Black smoke is a sign of incomplete combustion of fuel in the combustion chamber. Wear of cylinder liners and piston rings can cause insufficient compression pressure, which usually changes the cylinder compression stroke at the end of the mixing ratio, resulting in carbon fuel and combustion under anaerobic conditions. It does not drip or spray the ejector, so the fuel can not be completely mixed with the air in the cylinder.

（1）因?yàn)槿剂咸崆敖沁^大，所以燃料被迅速注入到燃燒室中。低壓和高溫汽缸不能點(diǎn)燃燃料。當(dāng)活塞向上移動(dòng)時(shí)，與氣缸壓力達(dá)到一定溫度時(shí)，在可燃混合物燃燒。

(1) Because the fuel advance angle is too large, the fuel is quickly injected into the combustion chamber. Low pressure and high temperature cylinders cannot ignite fuel. When the piston moves upward and the cylinder pressure reaches a certain temperature, the combustible mixture burns.

（2）供油提前角過小，過慢的燃料筒。之前形成可燃混合物，它要被分離，或者一些燃料的排出。與燃料氣體在熱解排出煙霧的形成。隨著越來越多的油進(jìn)入氣缸，所述氣體將不更完全的燃燒，從而降低了燃料。此外，礦用裝載機(jī)工作量大，燃料質(zhì)量差和更低的操作溫度所有的廢氣被排出。潤滑油進(jìn)入氣缸，它被加熱并蒸發(fā)成藍(lán)色石油和天然氣。

(2) Fuel cylinder with too small and too slow fuel supply advance angle. Before the formation of combustible mixture, it has to be separated, or some of the fuel discharged. With the formation of fuel gas in pyrolysis exhaust smoke. As more and more oil enters the cylinder, the gas will not burn more completely, thus reducing fuel consumption. In addition, the workload of mine loader is large, the fuel quality is poor and the operating temperature is lower, all the exhaust gas is discharged. The oil enters the cylinder, which is heated and evaporated into blue oil and gas.
