White smoke out of a 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?

White smoke points to some very specific conditions which can indicate a number of component or system failures. White smoke occurs in a diesel engine when the diesel fuel goes through the engine and reaches the exhaust without having been burned. The white smoke is a result of combustion temperature in your engine being too low. 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. 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. If it is smoking out the tailpipe , that means that either coolant or a bunch of excess fuel is getting. This causes white smoke. 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.

A problem with antifreeze might also be causing white smoke to come from the exhaust. Diesel Engines Blowing White Smoke from Exhaust. WHITE SMOKE occurs when raw diesel comes through the exhaust completely intact and unburned.

Some causes of this include. White Smoke White smoke can be caused by either excess fuel or an internal coolant leak in your engine. Don’t restrict the exhaust, just attempt to coat your fingers with the smoke.

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. It can be especially difficult to start a diesel engine during cold weather. Diesel engines need high compression and heat for fuel combustion. Diesels with an engine temperature below about F. The content of white smoke is finely atomized raw fuel and water vapor. Once that happens, the oil will become contaminated.

The first sign of having contaminated oil is white exhaust smoke coming out of the tailpipe. As this continues, the white smoke will begin to have a sweet odor smell that won’t go away. White smoke occurs as a result of combustion temperature being so low that only partial combustion occurs and the partially burned fuel that exits the exhaust is in the form of a white vapory smoke. If you don’t know what you are doing. For big diesel engines this is big because it is not uncommon for these vehicles to be used for more than a half-million miles before retirement.

Last week, just as I was thinking I had seen it all, a Ford F2was checked in that had a problem of Heavy White Smoke constantly emanating from the tailpipe at idle and worse as you increased RPM. White smoke means that the diesel fuel is not burning correctly due to a lack of heat in the combustion chamber.
