White smoke coming from diesel engine

What could make a diesel engine produce white smoke? What causes excessive white smoke from a diesel engine? Why does my diesel engine have white smoke? Why is my engine plowing white smoke? 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. Blowing white smoke is a red flag for your diesel engine , yet we see this happen all the time to our customers. In many cases, white smoke emanating from the tailpipe (often at idle once the engine reached operating temperature) typically means a worn out injector. But mostly, it is the incorrect injector timing in the cylinders. White smoke from exhaust diesel and petrol engine may be the signal of different car problems.

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. 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. White smoke in a diesel is caused by one of two things: engine burning coolant , or poor burning of fuel.

An engine burning coolant can be easily determined. First question, do you have to regularly add coolant? 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.

Be careful of white smoke as it will irritate your eyes and skin. Diesel engines can emit blue, black or white smoke from their exhaust while running, and each color can indicate a fault with a part or system. White smoke points to some very specific conditions which can indicate a number of component or system failures. White Smoke White smoke can be caused by either excess fuel or an internal coolant leak in your engine. This is a case where you’ll probably want to call in the diesel pros, but here’s a diagnostic tip: While the engine is smoking , hold your hand over the exhaust outlet for seconds or so.

WHITE SMOKE occurs when raw diesel comes through the exhaust completely intact and unburned. Diesel Engines Blowing White Smoke from Exhaust. Some causes of this include. Care must be taken when black smoke , white smoke , or both are emitted from the exhaust of a diesel engine. This pump is responsible for pumping diesel into the cylinders of a diesel engine.

Another possible issue is a worn-out injector, an injector with a cracked tip, or a bad harness. 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. This could be occurring either because the engine’s fuel injects are faulty, or as a result of low cylinder compression. 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.

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. White smoke means that the diesel fuel is not burning correctly due to a lack of heat in the combustion chamber.

This unburnt diesel contains minor toxins that may sting your eyes.
