White smoke from petrol car

One reason for white smoke is very common and completely harmless. Once the fuel and oil get mixed together, it will cause white smoke and maybe even blue smoke to come out of the tailpipe. 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. If it’s cold outside then you don’t have to worry about because condensation will cause steam to form when you first turn on your engine.

Steam is emitted by condensation in exhaust pipe which is seen at exhaust emission. The white smoke is the result of normal condensation which builds up inside the exhaust system. White smoke can be a big problem or not, depending on the thickness. Smoke rarely comes from the engine bay, and if it does, the issue is typically critical already. Usually, white smoke is water vapor or steam.

Water is being introduced into the combustion chamber. This is why your car smokes white in the mornings when it’s cold until it warms up and clear water condensation. If it smoking much at all you will have water coming out of the tailpipe. Thick, black smoke suggests that the engine is being flooded with gasoline.

The black smoke may show there is a return fuel line which is obstructed. Fuel injectors and sensors might also be damaged. Blue smoke is a clear sign telling your car engine is burning oil.

What happens is that the piston rings or the valve guide seals or other components of the engine are worn or broken, causing oil leaking. The oil will flow into the combustion chamber, then it is being burnt together with the fuel , creating blue smoke. Some wispy white smoke may not actually be smoke with a petrol car.

It could be water vapour on a cold start, which is actually a sign of a healthy engine. But if you get strong exhaust smell and see white smoke in large clouds it could be a problem. To be more specific, the white smoke you see is your diesel fuel, unburne or only partially burned. The commonest reasons for this lie in the fuel system.

They range from faulty fuel injectors to retarded fuel injectio n timing, or even low compression. When you start the car , the engine heats up, and these water droplets are emitted as white smoke. However, the white smoke persists it could mean that the coolant is leaking to the combustion chambers. A damaged head gasket or cracked engine block leak coolant.

This is a problem that’s fairly easy to identify, but at the same time, it is something that has to be fixed right away because the longer the fuel stays in the combustion chamber, there is a greater possibility for an explosion. You may commonly see white smoke coming from the exhaust on cooler days upon starting. This is likely due to steam created due to the engine burning off the condensation. If you notice that your car is blowing white smoke. This is usually caused by overheating the engine and usually causes the oil to be saturated with water.

This is particularly bad because the oil is not effective at protecting the bearings and can ruin an engine quickly. What does WHITE smoke from my exhaust mean? The most likely culprit is one or more worn fuel injectors. Other reasons could be a clogged fuel return line.

Black smoke is usually the.
