White smoke from petrol engine

This excess fuel cannot properly burn in the engine and instead comes out as white or gray smoke out of your tailpipe. 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. Normal causes for white smoke in the engine bay During cooler days it is normal to see some white smoke coming from the engine.

One of two conditions is responsible for white smoke blowing out of your exhaust. First is normal condition (so you don’t have to panic) and the second is a not so normal condition which should be fixed as soon as possible. Purpose of fuel injectors is to provide an engine with sufficient amount of fuel and to make sure that neither more nor less fuel is provided to the engine.

In case if these injectors get faulty, the improper supply of fuel led to over burning of fuel resulting in gray, dense smoke from exhaust. 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. This is generally steam caused by condensation.

Engine smokes: Blue or dove-colored smoke. Oily smoke may have blue color with various hues - from transparent blue to blue- white , depending on the engine operating. A car engine can smoke for several reasons. This could be caused by valve stem seals, worn rings, a plugged PCV valve, not changing the oil for extended periods, too high of an oil level or transmission fluid being sucked into the intake manifold from a bad vacuum modulator. Usually, white smoke is water vapor or steam.

Water is being introduced into the combustion chamber. 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. The white smoke is steam. Diesel engines usually have more issues with smoke compared to petrol engines.

If a diesel engine is billowing black smoke , which is mostly the case, it could be one of a number of issues. 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. Excessive exhaust smoke may be the first sign that your engine needs attention. If excessive exhaust smoke is visible, you likely have a real problem.

Fuel injectors and sensors might also be damaged. A final problem which can be diagnosed from black smoke is problem with the air filter. Smoke from engine or exhaust Inspection Service You can learn a lot about the health and well being of your car from the color of its exhaust. If it’s operating in tip-top shape, tailpipe emissions should be nearly undetectable. Note: If the engine has to be tilte ensure the spark plug is facing upwards to help prevent oil from escaping the crankcase.

On cold winter days, it is common to see white smoke from exhaust pipe as soon as you start the car. As the engine warms up after a few minutes, this white smoke will not be reduced because condensation is dissipated. A steady stream of white smoke during normal driving conditions points to fuel vapors, or in some cases, raw fuel exiting the exhaust. Worn or defective glow plugs, improper engine timing and defective fuel pump pressure will allow excess fuel to exit the exhaust in the form of white smoke.

There’s white smoke and then there’s white smoke. 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. How to Stop White Smoke from the Exhaust.

You may commonly see white smoke coming from the exhaust on cooler days upon starting. Blue smoke comes from oil burning in the cylinders. Oil usually gets in through either a leaking intake valve seal or through worn piston rings.

Cylinder misfire, loss of power or a loss of fuel economy may accompany any color exhaust smoke.
