Diesel truck white smoke

What does it mean when a diesel engine is blowing white smoke? What could make a diesel engine produce white smoke? What is the smog law for diesel trucks? Why do diesel trucks sometimes leave black smoke? 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. 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. WHITE SMOKE 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. L Cummins engine, and I am having some problems. 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.

Sometimes diesel engines emit a white smoke while starting. It can be especially difficult to start a diesel engine during cold weather. This video should only be used as guidance and not as an absolute-guide. If you don’t know what you are doing. What causes white exhaust smoke , what causes an.

In this video we show you why! WHITE SMOKE occurs when raw diesel comes through the exhaust completely intact and unburned. Some causes of this include. Continuous white smoke while driving is one of them.

But mostly, it is the incorrect injector timing in the cylinders. Typically, this white smoke indicates a serious fuel injection problem. The white smoke is due to unburnt fuel caused by improper heating. The commonest cause of white smoke is likely injector pump timing.

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. After a short amount of driving, the white smoke should lessen. It’s common for drivers who have lived in a warm climate like California and then move to colder region to worry about this but it’s harmless and perfectly normal. If this is the case, there is nothing wrong with your truck.

In my experience white smoke is deffinately water in the fuel,i would change were you buy your fuel after you have run your tank dry. This is due to the fact that colder air, which is more dense than warm air, lowers temperatures in engine cylinders at the end of the compression stroke. This colder air leads to reduced combustion of the fuel that has been injected into cylinders.

Basically, smoke from a diesel engine indicates that something is not right. It should be taken as an indication that there is a problem existing (or developing), that will potentially shorten the engine life, or result in unnecessary costs. Diesel Smoke tells YOU a Story.
