Common cause to diesel exhaust black smoke
Black smoke contains more carbon particles, which are signs that the combustion of fuel takes place is not perfect, the lack of air or excess fuel diesel. Motivation is not stable and fuel costs to no avail.
Black smoke usually occurs when the accelerator, but the black smoke will go away after a few seconds. You can easily see this phenomenon on a large bus usingdiesel. Driving the accelerator to speed, diesel fuel is added to increase capacityand speed, but immediately the air is not enough, a mixture of excess fuel andblack smoke appeared. After a few seconds the engine to work stable, black smoke disappears. But if the car is emitting black smoke constantly while on the road, the engine may have met one of the following problems.
Clogged air filter, not enough ventilation pipe or turbo work less effective. Lack ofoxygen to burn fuel are loaded, causing black smoke. Please clean the air filterbefore going to find another cause.
Diesel also emitting black smoke when using the wrong fuel. Not rare cases ofmisuse of fuel, or use poor quality fuel. Due to lack of driving experience.
Another cause is the fuel injection system malfunction. Diesel fuel is not torn by badnozzle, or pressure spraying is not guaranteed, wrong time of spraying, or sprayingtoo long to incomplete combustion of fuel.
Car has run 160,000 to 190,000 km or black smoke discharged infrequently, andmotivation shake, maybe one of the jets had problems. Jets are worn excessively, causing fuel to leak into the high pressure chamber without being torn to piecesand will not be burned completely.
For common-rail systems, oil pressure sensor fails, the control stuck, ECU (controlcenter) can not control the pressure throughout the system, incorrect calculations ofspray. Fuel is fed into the combustion chamber more than necessary.
Finally, can the car's slightly less, cylinder wear, segment not contained, or too tight,worn valve. The pressure of compressed air has not reached the value necessary to completely burn diesel. Use the meter test chamber pressure to a final conclusion whether this is not the cause of black smoke.
