Why does diesel engine lose power and smoke?
Why does diesel engine lose power and smoke?
Dirty air filter. Black smoke indicates that the fuel is not burned properly. The internal combustion process in diesel cars requires a certain mixture of fuel and air. The carbon chucks could clog your EGR valve, which will result in loss of power, fuel inefficiency and emission of black smoke from your exhaust.
Why are my fuel pump injectors not working?
In 2006, diesel fuel production was tweaked to compensate for ultra low sulfur diesel fuel (ULSD), and diesel engine owners have noticed more “dirty fuel” difficulties than before. If your main goal in life was to destroy diesel fuel pump injectors, you’d run your car with the fuel tank as close to empty as possible.
Why do I have white smoke coming out of my injector?
Other causes of white smoke include lack of compression, or water/coolant entering the combustion chamber. BLACK SMOKE. Black smoke indicates excess fuel is being injected into the combustion chamber and/or not enough air is present. This can be caused by worn/leaking injectors or restrictions in the air intake system.
What causes a Duramax injection pump to fail?
As a result (allegedly), the lack of lubrication in the fuel can cause a premature failure of the injection pump, to a point where it won’t allow the LML Duramax to run. You can be driving down the road and everything seems normal, and when the pump fails, the truck just shuts off.
What’s the pressure of a diesel injector pump?
Today’s diesel fuel injection pumps are under pressure – even more pressure than what was once considered “normal.” Around 15-20 years ago, it was common for fuel injector pumps to process fuel in a system at around 10,000 to 15,000 psi (pounds per square inch). But that’s only about half of what engines are expected to do today.

What causes white smoke from a fuel pump?
Continuous “light” white smoke 1 A clogged fuel filter 2 Low pressure in the fuel pump (Air in the fuel) 3 Faulty or damaged injectors 4 Incorrect injection timing (Worn timing gear or damaged crankshaft keyway). 5 Low cylinder compression (caused by leaking or broken valves, piston ring sticking, cylinder ring wear, or cylinder glaze)
What does black smoke mean in an injector?
BLACK SMOKE. Black smoke indicates excess fuel is being injected into the combustion chamber and/or not enough air is present. This can be caused by worn/leaking injectors or restrictions in the air intake system.
