White smoke on startup diesel

What could make a diesel engine produce white smoke? Can bad diesel cause white smoke? Why does diesel engine produce black smoke on start-up? What makes a diesel blow blue or white smoke?

The white smoke is due to unburnt fuel caused by improper heating. Diesel engines need high compression and heat for fuel combustion. In very cold temperatures, the heated exhaust can freeze into minute fuel droplets when exiting the exhaust and produce a more prolonged emission of white smoke for a very short period of driving time.

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. When the engine is cold or has cooled back down I get a lot of white smoke at startup.

This video should only be used as guidance and not as an absolute-guide. If you don’t know what you are doing. 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 often occurs when there is either too much fuel being injected into the combustion chamber, or not enough heat to burn the fuel.

If it is smoking out the tailpipe , that means that either coolant or a bunch of excess fuel is getting. 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.

Normally, it would happen at startup in cold weather with lower compression engines and retarded timing. Now that doesn't necessarily mean it has to cool down to col as after it sits all night. Condensation that accumulates inside the exhaust pipes, converter and mufflers can produce a puff of white smoke upon diesel engine start-up.

When it’s cold outside and you notice white smoke at startup, then you probably have nothing to worry about. When the warm or hot exhaust gases meet cold outside air, condensation and steam is a result. After a short amount of driving, the white smoke should lessen.

This is because the two stroke engine have back up oil which normally enters the fuel chamber to lubricate the piston. 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.

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. When the fuel pump injection timing is off, it is difficult to determine the root cause. Has the engine got a fuel pre-heat system for starting in cold weather?

If the pre-heat ceases to function it can be like electing a pope for several minutes until the engine warms up.
