WHITE SMOKE occurs when raw diesel comes through the exhaust completely intact and unburned. Some causes of this include. Condensation that accumulates inside the exhaust pipes, converter and mufflers can produce a puff of white smoke upon diesel engine start-up. 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.

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. The combination of the coolant and engine oil will create a milky appearance in the smoke. All it takes is for just a little bit of coolant to get into the combustion chamber for white smoke to be produced. Blowing white smoke is a red flag for your diesel engine, yet we see this happen all the time to our customers.

If the exhaust smells almost like bug spray, it is.

The commonest cause of white smoke is likely injector pump timing. 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. Consequently, a proper running diesel engine should produce no visible smoke from the exhaust. If there is smoke coming from the exhaust it could indicate a more serious problem with the engine.

This article will help diagnose the underlying causes of diesel engine smoke. Diesel engine smoke comes in three colors: white , black and blue. This is generally steam caused by condensation.
