White smoke in diesel

Why does my diesel engine have white smoke? 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. What makes a diesel smoke? Then hold your hand up close to your face.

Typically, this white smoke indicates a serious fuel injection problem. An engine burning coolant can be easily determined. First question, do you have to regularly add coolant?

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. If it is smoking out the tailpipe, that means that either coolant or a bunch of excess fuel is getting. 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 white smoke occurs during a startup in freezing temperatures, then goes away, it usually indicates frozen deposits of soot which expanded around the rings then burned away once the engine warmed up.

In the cold weather, the white smoke can be quite normal, but in some situations, it is not. Continuous white smoke while driving is one of them. 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. This is the complete guide to white smoke from a diesel.

Raw diesel comes through the exhaust completely unburned 2. Water entering combustion chamber. The temperature in the combustion chamber is too low. Now, let’s look at three scenarios. White smoke occurs for one of three reasons 1. This pump is responsible for pumping diesel into the cylinders of a diesel engine.

This might be caused from the engine being too cool to burn the fuel, low compression in cylinder(s), fuel injection timing, defective fuel injector, burnt out glow plugs, clogged air filter or poor quality fuel. 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.

Consistent smoke coming from the exhaust most likely indicates a deeper internal problem with the engine. A small puff of smoke during quick acceleration is acceptable with older diesel engines due to a lag before the turbocharger’s air flow can match the increased volume of diesel fuel injected into the cylinders. This video should only be used as guidance and not as an absolute-guide. There’s white smoke and then there’s white smoke 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. If you don’t know what you are doing. 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. Technically, the white color is caused by the light-scattering characteristics of the re-condensed droplets of fuel (un-burned or partially burned) larger than one micron.

When the fuel pump injection timing is off, it is difficult to determine the root cause.
