Black smoke is caused by a very rich fuel-to-air ratio..
What does it mean when a diesel blows black smoke?

Why do diesels smoke under acceleration?
Dirty air filter. Black smoke indicates that the fuel is not burned properly. The internal combustion process in diesel cars requires a certain mixture of fuel and air. … This faulty process forms solid carbon residue, which causes a black smoke from the exhaust of the diesel engine when accelerating your car.
How do I fix white smoke from exhaust?
How To Fix White Smoke From Exhaust IssueStep 1: Inspect The Intake Gasket. There is a gasket that seals the manifold to the head inside the vehicle. … Step 2: Inspect The Head Gasket.

Why is my Ford diesel blowing white smoke?
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. Un-burned fuel travels through the exhaust system & exits out the tailpipe which will produce a scent of rich, un-burnt diesel.
What is GREY smoke from exhaust?
White smoke from the exhaust: This could be steam caused by condensation in the exhaust pipe or a more serious issue caused by an engine coolant leak. … Grey smoke from the exhaust: This could be excess oil, a PCV valve failure or a transmission fluid leak on automatic cars.

What causes white smoke in a diesel?
White smoke occurs when diesel fuel isn’t reaching the temperatures required to burn, causing it to come through the exhaust intact. … Clogged Fuel Filter. 2. Incorrect Injection Timing (due to a bad injector pump, worn timing gear, or a compromised crankshaft keyway)
Is it normal for a diesel to smoke?
A little black smoke is normal on a properly functioning diesel, but keep an eye on the amount of smoke at different RPMs and loads so that you will be able to tell if something is amiss.
