Diesel car blowing white smoke

What does it mean when a diesel engine is blowing white smoke? What can cause white smoke from a diesel? What could make a diesel engine produce white smoke? What is the reason for diesel smoke? One reason for white smoke is very common and completely harmless.

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. You would obviously want to fix this leak very fast because if the engine components are not being lubricated properly by the oil, then they’ll start to get worn out and damaged rather quickly. Condensation that accumulates inside the exhaust pipes, converter and mufflers can produce a puff of white smoke upon diesel engine start-up. 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. Sometimes diesel engines emit a white smoke while starting. The white smoke is due to unburnt fuel caused by improper heating.

Diesel engines need high compression and heat for fuel combustion. It can be especially difficult to start a diesel engine during cold weather. If your car has a diesel engine , then the white smoke might be indicating that there is a problem with the fuel pump injection. When the fuel pump injection timing is off, it is difficult to determine the root cause. When combustion is incomplete, a diesel mist comes from the exhaust.

It is very common when starting a diesel in very cold weather. How to solve the white smoke coming out of a. 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. 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.

White smoke occurring on a diesel engine at cold start is not too uncommon on cold frosty morning. Continuous smoke -filled white clouds while driving could also be a sign that fouling deposits are developing around the piston rings. 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. 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.

Diesels with an engine temperature below about F. 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. But if this condition continues to persist and there’s a loss in power, it indicates that the car is losing compression and hence belching white smoke. In very cold weather when a diesel car has not warmed up, some white smoke is normal.

This could be occurring either because the engine’s fuel injects are faulty, or as a result of low cylinder compression. Lots of Blue Smoke When Starting Cars (not Diesel ): Bad Valve Seals. If you see blue smoke coming out of exhaust after you have parked your car for a while and the engine is not a diesel , the probable culprit is Bad Valve Seals. Each engine has valves that open and close.
