    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.
