Continuous white smoke from exhaust

This will cause white smoke , along with the idle issue. You may commonly see white smoke coming from the exhaust on cooler days upon starting. 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 can be nothing to be concerned about if it’s thin, like vapor. This is generally steam caused by condensation.

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. I assume the gas then fell back down where the injectors sat. The black smoke may show there is a return fuel line which is obstructed.

Fuel injectors and sensors might also be damaged. A final problem which can be diagnosed from black smoke is problem with the air filter. As the engine warms up and the condensation dissipates the white exhaust smoke (steam) is no longer seen. The main cause of smoke from exhaust when accelerating is due to a burning coolant or transmission fluid problem. A functioning oil burner generates little smoke during operation.

Excessive levels of oxygen within the combustion chamber can cause inefficient fuel burning and lead to the dense, white smoke emanating from your chimney. When the engine is again started the exhaust system will heat up evaporating the water causing steam. But excessive white smoke likely means coolant is leaking into the engine combustion chambers. Condensation can turn to vapor, providing what looks like white exhaust.

I own a Bajaj Discover 1CC. It is just months old. Thick white smoke upon startup, and continuous white smoke when running. Replaced Piston Rings, Head Gasket and some injectors.

Could be coolant leak, Gasket leak, Piston Rings leak or dirty injectors. Have it compression check first. It’s just one of the byproducts of combustion, and when the engine parts and exhaust pipe are cooler, the water vapor condenses to form steam, which is the white smoke you see. Technically, the white color is caused by the light-scattering characteristics of the re-condensed droplets of fuel (un-burned or partially burned) larger than one micron. You probably notice that you get white smoke from your exhaust , especially in cold weather.

When you starts your engine, the system heats up under a cold atmosphere, and this causes the steam or the white smoke that you see. Continuous “light” white smoke In order to run correctly, a diesel engine needs precise timing of the injector pump and proper pressure. Any decrease in the pressure or delay in the delivery of the fuel to the combustion chamber will cause an incomplete combustion and you will have white smoke.

Observe the white smoke and water escaping from the tail pipe. If white smoke starts to escape immediately, water begins to drip as the car warms up, and your exhaust smells of antifreeze, there is a coolant leak inside your engine. Head gasket, water jacket, Intake manifold gasket, etc.

Pressure check the radiator and cooling system and check for leaks. This may occur, for instance, because of restrictions in the injected elbow. Why you see Blue Smoke From Exhaust. If you are seeing Blue Smoke From Your Exhaust this means that your car engine is burning oil. It really does not smell very good and is not good for your health to breath in.

This smoke should not be confused with White Smoke you will see when a car first starts up.
