When petrol is used in diesel engine, the engine will not work as gasoline (petrol) has high ignition temperature and therefore has to be ignited by spark-ignition. Diesel engine on the other hand works on the principal of self-ignition in compressed fuel which is not possible with petrol.

When diesel is used in petrol engine, there will be sudden combustion in the fuel due to spark ignition  bcoz diesel has low ignition temperature. This will lead to high knocking, which is absolutely undesirable.

RE: Petrol Engine... good question.....

More than a few drops of the wrong fuel is likely to wreck the engine.

A diesel/air mixture has to be compressed much more than a petrol/air mixture so the engines are built differently from each other.

I think both the engines are built up according to their requirements such as compression ration spark plug for petrol and injector for diesel engine and many more different things. May be we will be seeing hybrid engines in near future.
