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

黑烟是燃烧室内燃料不完全燃烧的迹象。缸套和活塞环的磨损会导致不充分的压缩压力，这通常会改变气缸压缩冲程在所述混合比的端部，由此在厌氧条件下的碳的燃料和燃烧。它不滴或喷雾喷射器，因此，燃料不能完全与在汽缸中的空气混合。

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）因为燃料提前角过大，所以燃料被迅速注入到燃烧室中。低压和高温汽缸不能点燃燃料。当活塞向上移动时，与气缸压力达到一定温度时，在可燃混合物燃烧。

(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）供油提前角过小，过慢的燃料筒。之前形成可燃混合物，它要被分离，或者一些燃料的排出。与燃料气体在热解排出烟雾的形成。随着越来越多的油进入气缸，所述气体将不更完全的燃烧，从而降低了燃料。此外，矿用装载机工作量大，燃料质量差和更低的操作温度所有的废气被排出。润滑油进入气缸，它被加热并蒸发成蓝色石油和天然气。

(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.
