White smoke 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. 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. If you are having a diesel , white smoke may be unburned fuel or coolant going through the 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. 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.

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. 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?

Second question, does the exhaust sm. White smoke points to some very specific conditions which can indicate a number of component or system failures. White smoke can be caused by either excess fuel or an internal coolant leak in your engine. While the engine is smoking , hold your hand over the exhaust outlet for seconds or so.

Don’t restrict the exhaust, just attempt to coat your fingers with the smoke. Then hold your hand up close to your face. 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. WHITE SMOKE occurs when raw diesel comes through the exhaust completely intact and unburned.

Some causes of this include. 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. The white smoke is due to unburnt fuel caused by improper heating.

It can be especially difficult to start a diesel engine during cold weather. The content of white smoke is finely atomized raw fuel and water vapor. When combustion is incomplete, a diesel mist comes from the exhaust. It is very common when starting a diesel in very cold weather.

It can occur from bad rings or valves not properly sealing the combustion chamber,. 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.

Black smoke from a diesel engine when accelerating is not always a serious problem. Most diesel cars (if not all) emit a small amount of black exhaust smoke while accelerating. It takes some time for the engine system to develop enough revolutions (RPM) and power to burn the fuel. 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. 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.
