Runaway of diesel engine exhaust pipe when a large number of black smoke how to solve?       

Runaway of diesel engine exhaust pipe when a large number of black smoke which is due to excessive diesel cylinder caused by burning.

1, if there is a scar or plunger plunger sleeve valve assembly deformation caused by oil tight, will lead to the plunger in the largest oil position is stuck, when the engine speed increases, the injection pump governor loses the piston automatic steering oil supply quantity decreases in the role of the throttle handle also does not play a role, resulting in excessive diesel into cylinder.

2, diesel oil is not clean or diesel filter failure, so that dirt or impurities of diesel oil directly into the injection pump, the plunger stuck in the maximum oil supply position. To this end, the diesel 48h above precipitation before use, gas should also prevent dust mixed with rain.

3, if the governor assembly tight, improper adjustment; in the dirt stuck or mechanical governor governor spring lever, because the temperature is too low to make fracture; viscosity of lubricating oil inside the governor increases, thus the fuel injection pump to automatically adjust the sensitivity of oil dropped; are likely to lead to a plunger lag at maximum throttle position. To this end, the winter engine after the car should be idling for a while and low speed running a distance, to adjust the temperature rise in the regulator, you can increase the speed of full load operation.
