What is the problem of white smoke in diesel engine?

White Smoke: White smoke coming from the exhaust usually points to one point of failure: the injectors. Usually, white smoke indicates that the diesel fuel is not burning correctly. Unburned diesel fuel will make its way through the exhaust completely unused.

Can a blocked DPF cause white smoke?

In a Diesel engine with a Diesel particulate filter (DPF) system, high-sulfur fuel causes white smoke containing odorous and harmful pollutants during DPF regeneration. The white smoke was observed when the catalyst temperature was more than 450°C, under conditions such as the early stage of DPF regeneration.

What are symptoms of bad diesel injectors?

5 COMMON SYMPTOMS OF FAULTY DIESEL FUEL INJECTORS

• Trouble starting the vehicle or uneven idling. The engine cranks but doesn’t start unless you crank it for a long time.
• Misfire.
• Smell of fuel.
• Dirty emissions.
• Increased fuel consumption and poor miles per gallon.

Can a bad fuel pump cause white smoke?

Kettle’s on. Re: White smoke and oil emissions form crank case breather on diesel engine. If oil is coming out of the breather and there is a shortage of oil in the crankcase, then these things are most probably related. The cause is insufficient maintenance activity.

What does it mean when there is smoke coming out of exhaust?
