Diesel car white smoke

What could make a diesel engine produce white smoke? What does it mean when a diesel engine is blowing white smoke? What can cause white smoke from a diesel? Why does my diesel engine have white smoke?

But mostly, it is the incorrect injector timing in the cylinders. What is the difference between White Smoke From Exhaust Diesel Engine and Petrol Engine? White smoke from exhaust diesel and petrol engine may be the signal of different car problems.

The most noticeable symptom of internal coolant leakage is when the white smoke is billowing out of the exhaust pipe and leaves a sweet odor in the air. If your car has a diesel engine , then the white smoke might be indicating that there is a problem with the fuel pump injection. When the fuel pump injection timing is off, it is difficult to determine the root cause. The timing is the key aspect here, as the fuel is injected only slightly before the top dead center of that cylinder’s compression stroke.

Sometimes diesel engines emit a white smoke while starting. The white smoke is due to unburnt fuel caused by improper heating. Diesel engines need high compression and heat for fuel combustion. It can be especially difficult to start a diesel engine during cold weather. Diesels with an engine temperature below about F. White smoke often occurs when there is either too much fuel being injected into the combustion chamber, or not enough heat to burn the fuel.

Diesel Engines Blowing White Smoke from Exhaust. This causes white smoke. WHITE SMOKE occurs when raw diesel comes through the exhaust completely intact and unburned.

Some causes of this include. OLD SCHOOL Wheel Standing Championships at Byron Dragway OLD SCHOOL CARS AMERICAN MUSCLE. Why Does My Diesel Smoke So Badly. The latter issue can be put down to a problem with engine valves, the engine’s piston rings or the cylinders.

Care must be taken when black smoke , white smoke , or both are emitted from the exhaust of a diesel engine. In very cold weather when a diesel car has not warmed up, some white smoke is normal. But if this condition continues to persist and there’s a loss in power, it indicates that the car is losing compression and hence belching white smoke. White smoke occurs in a diesel engine when the diesel fuel goes through the engine and reaches the exhaust without having been burned. The commonest cause of white smoke is likely injector pump timing.

In order to function properly, a diesel engine needs precise timing of the injector pump and high pressure. So, any decrease in the pressure or delay in the fuel delivery to the combustion chamber will result in incomplete combustion, leading to white smoke. One of two conditions is responsible for white smoke blowing out of your exhaust.

First is normal condition (so you don’t have to panic) and the second is a not so normal condition which should be fixed as soon as possible. Black Smoke Black smoke coming out of your car probably means that the engine is getting either too much fuel or too little oil. I wouldn’t necessarily say the white smoke would be from the DPF.

If you have ever been behind a car that is going through the regeneration cycle of the DPF, you will see the amount of black smoke that will come out from it. Diesel cars will usually produce white smoke from the following three symptoms.
