They smoke when the diesel is burned with insufficient oxygen.

Diesel is less volatile, so doesn't combust as readily as petrol. This means you quite often have unburnt fuel passing into the exhaust which gives you your black smoke.

Because they burn heavy oil rather than light fuel like petrol Monster.

They also generate loads of soot in the exhaust as a result of this when driven normally.

Some of this is expelled under hard driving, thus making the smoking even more apparent.

Some modern diesels are far more efficient and clean burning. The volkswagen PD unit is a good example and rarely smokes if at all.

Hope that helped.
