What causes black smoke from loaders?
Diesel oil - filter (air filter, diesel filter) - fuel injection pump - nozzle and so on, are likely to cause black smoke, it is best to say in detail
The causes of black smoke in loaders and the ways to remove them are as follows:1. The air filter is blocked and the air cylinder is not inflated enough. The air filter element should be cleaned or replaced;Two, supercharger failure, causing insufficient supply pressure, so that the diesel engine combustion is incomplete, should overhaul turbocharger;Three, injector atomization or drip phenomenon, should repair the effect of injector nozzle replacement, when necessary (needle valve);Four, oil supply time adjustment is improper, there are two kinds:A. exhaust pipes emit black smoke, while the cylinder is accompanied by crisp knocking and rough work. This phenomenon is generally caused by premature delivery time. The oil supply time is too early and usually causes difficulties in starting.The B. exhaust pipe emits black smoke, while there is flame in the muffler and the sound is muffled. This phenomenon is due to the late delivery time. Oil supply time is too late, often cause diesel overheating, exhaust temperature rise, and may even burn parts.In addition, a diesel engine with an oil supply angle advance device may emit black smoke at high speed. It may also be due to the damage of an automatic feed advance device in the fuel supply angle, and an automatic fuel injection angle advance device shall be disassembled. If the fuel supply time is improper, the method mentioned above can be checked and adjusted.Five, each cylinder uneven oil supply.The exhaust pipe emits black smoke, meanwhile, the machine vibration is serious, and the oil supply for individual cylinder is too much. It can be checked out by "broken cylinder method";Six, poor quality diesel.Poor quality diesel, poor atomization, resulting in incomplete combustion, the tank should be cleaned and replaced by diesel oil.
Generally check the air intake first to see if the filter is dirty. It's the fuel system!
