Can we use gasoline is used in a Diesel engine?

No, If gasoline is inserted into the car or vehicle with a diesel engine, then it can cause a lot of problems to the engine. The diesel engine is not dependent on the spark plug unlike other engines, whereas the gasoline engine depends on the spark plug to set fire to the combustion chamber.

If gasoline enters the diesel engine there will be no ignition and lubrication. The fuel system will get damaged as it will affect the fuel pump, filter, and injectors. If there is an unnatural detonation, the shock waves could destroy various components of the engine like pistons, wrist pins, and rods. Ultimately it will result in the damage of the engine as well.
