Here's why:
* Different combustion processes: Diesel engines are designed to burn diesel fuel, which ignites under high compression. Petrol engines use spark plugs to ignite the fuel.
* Fuel injection systems: Diesel and petrol engines have different fuel injection systems, designed for their respective fuels.
* Engine compression ratios: Diesel engines have much higher compression ratios than petrol engines, making them unsuitable for petrol.
Trying to run a diesel car on petrol will result in serious damage:
* Engine damage: The wrong fuel will cause misfiring, knocking, and potential engine damage.
* Fuel system damage: The fuel injection system and other fuel-related components are not designed for petrol.
* Emissions issues: Burning petrol in a diesel engine will result in excessive emissions.
If you accidentally put petrol in a diesel car:
* Do not start the engine!
* Contact a professional mechanic immediately to have the fuel system drained and cleaned.
Remember, always use the correct fuel for your vehicle to ensure its longevity and safe operation.
