White smoke in exhaust diesel

What does it mean when a diesel engine is blowing white smoke? What could make a diesel engine produce white smoke? What makes a diesel blow blue or white smoke?

What causes excessive smoke from diesel engine? This typically occurs due to the engine being too cool to burn the fuel , often resulting from low compression in one cylinder, problems with the fuel injection timing or a defective fuel injector. A worn or blown head gasket , particularly near the exhaust port side, will cause liquid coolant to enter the cylinders and pass through the exhaust in the form of vaporous steam. A cracked engine block or cylinder head will produce the same effect. The good news is, not all white smoke signals problems in your car, as some can be due to normal condensation too.

A rule of thumb though is the thicker the white smoke , the greater is your problem. 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.

If white smoke continues to come out of your exhaust while the car is running, there are other issues at fault. One cause of white smoke from the exhaust might be the engine leaking coolant. If the engine leaks coolant , it will be burned by the heat of the engine and then come out as smoke from the exhaust. 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. Raw diesel comes through the exhaust completely unburned. Water entering combustion chamber. The temperature in the combustion chamber is too low.

These things can occur for several reasons. What is wrong really depends on the “type” of white smoke you have. I wrote a article about it. Usually, white smoke indicates that the diesel fuel is not burning correctly. Unburned diesel fuel will make its way through the exhaust completely unused.

Be careful of white smoke as it will irritate your eyes and skin. If you the white smoke consistently comes out and the sweet odor smell is present, then it is definitely a problem with your coolant leaking. This is usually the last color of smoke you want to see, particularly on gas cars.

If the smoke is thin, and goes away relatively quickly, than it is merely condensation. However, thicker, longer lasting smoke is a much larger headache. Your engine is more than likely burning coolant.

Another possible issue is a worn-out injector, an injector with a cracked tip,. Usually with white smoke you’re either spitting out vaporous un-burned diesel or steam. To tell the difference between the two is fairly easy, if your engine is making white smoke right from start up and the smoke sits on the water without disappearing you’re most likely looking at un-burned diesel. There may be several reasons for a car smoking white smoke from the exhaust. In this oneHOWTO article, we are going to talk about how to stop white smoke from the exhaust , no matter what the underlying reason is.

Is white smoke a bad thing? This could be occurring either because the engine’s fuel injects are faulty, or as a result of low cylinder compression.
