Common Causes of Vehicle Smoke
Diesel Engines Don't Have To Smok
e:
Although diesel engines emit some smoke on acceleration, they should not smoke constantly. All vehicles, including diesels, are subject to the same smoking law as gasoline engines.
Prevention Is Key:
While it is normal for smoke to appear during the first few seconds after engine startup only, a well-maintained vehicle should not emit visible exhaust. Preventing a vehicle from smoking often involves simple maintenance procedures.
