Not a problem for me since I drive a petrol engine, but I was curious to know what causes the small puffs of black smoke sometimes seen when a diesel engine accelerates suddenly.
My understanding is that when suddenly accelerating, there is a momentary inbalance between the air / fuel mixture and some unburned diesel is expelled out of the exhaust, is this right?
