White smoke from car diesel

What does it mean when a diesel engine is blowing white smoke? Why would a diesel engine blow white smoke? What causes excessive white smoke from a diesel engine? But mostly, it is the incorrect injector timing in the cylinders. 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. 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.

One of two conditions is responsible for white smoke blowing out of your exhaust. This causes white smoke. 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.

You may commonly see white smoke coming from the exhaust on cooler days upon starting. WHITE SMOKE occurs when raw diesel comes through the exhaust completely intact and unburned. Diesel Engines Blowing White Smoke from Exhaust.

Some causes of this include. 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. Black smoke and white smoke are signals of a dangerous engine Care must be taken when black smoke , white smoke , or both are emitted from the exhaust of a diesel engine.

White smoke occurs in a diesel engine when the diesel fuel goes through the engine and reaches the exhaust without having been burned. White smoke in a diesel is caused by one of two things: engine burning coolant, or poor burning of fuel. An engine burning coolant can be easily determined.

First question, do you have to regularly add coolant? Several factors may cause your car exhaust to emit white smoke. It could be a minor issue or a big problem depending on the density of the smoke. White smoke arises from the normal condensation of wispy vapors in the exhaust pipe.

If the smoke is thin like air vapor, then, you have got no problem. The white smoke is due to unburnt fuel caused by improper heating. The commonest cause of white smoke is likely injector pump timing. Diesel engines need high compression and heat for fuel combustion. 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. White smoke points to some very specific conditions which can indicate a number of component or system failures. When combustion is incomplete, a diesel mist comes from the exhaust. It is very common when starting a diesel in very cold weather.
