Heavy white smoke from diesel engine

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. They range from faulty fuel injectors to retarded fuel injectio n timing, or even low compression.

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. 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 points to some very specific conditions which can indicate a number of component or system failures.

When the timing is not what it’s supposed to be, your engine will essentially be running rich which will cause fuel to not completely burn and instead exit out of the exhaust as white or gray smoke. 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. A brand new diesel engine running at full load will experience a little bit of blow-by upon startup.

Blow-by is a condition where diesel fuel, air and vapor are pushed past the rings into the crankcase of the engine. On the common rail Cummins, white smoke is more characteristic of an injector problem. If the exhaust smells almost like bug spray, it is.

Why is my engine plowing white smoke? 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.

If, however, a preheat device such as glow plugs or an air-intake heater are malfunctioning, the production of white smoke may be excessive and longer lasting. Trucks do not smoke during regen White smoke on diesel indicates either completely unburnt fuel or water being in the combustion cycle. Since it went away as the engine warmed up, it sounds like you may have a bad glow plug and a cylinder thats not getting hot enough to burn the fuel while cold.

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. If smoke is being release then this is indicative of a problem.

HOWTO looks at all the possible reasons why white smoke is coming from your exhaust pipe. If the problem is oil thatrsquo;s too thin, there will probably be blue smoke at all revs, but especially after a period of idling and also when the engine is at high revs or under heavy load. 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.

Basically, smoke from a diesel engine indicates that something is not right.
