We know that, petrol is ignited by spark and diesel is ignited by compression ignition, the volatility of the petrol is greater than diesel. The spark plug produces the spark only at some places, not at all the point of air-fuel mixture. … This is the reason for Why diesel cannot be used in petrol engine?.
Why does diesel not work in a petrol engine?
Petrol has higher auto ignition temperature and it won’t burn at the compression ratio of a diesel engine without external help. So, the engine won’t run. Whereas when you use diesel in petrol engine, it’s dangerous. Diesel burns with more power and it may damage the engine partly or completely.
Is diesel bad for petrol cars?
Diesel will cause serious damage to a petrol engine if you allow it to circulate, particularly if your car is of the direct-injection variety. Fuel injectors that are designed to use unleaded will not take kindly to diesel.

Why diesel is not used in bikes?
Due to the high compression ratio, the diesel engine produces more vibration and noise as compared to the petrol engine. It is not possible for a light vehicle to handle this high vibration and noise. That’s why diesel engines are not used in a motorcycle.
Does diesel engine use carburetor?
Diesel engines are also IC engines. However, in Diesel engines, there is no carburetor. Only air is compressed to much higher pressures and the fuel is injected into the compressed air. As the fuel and air are mixed, the fuel evaporates and ignites (hence called compression ignition).
What is the disadvantage of diesel engine?

Diesel fuel usually costs more. Servicing can be more expensive, although you don’t need to do it as often. Diesel cars produce a lot more NO2. Diesel engines can be slightly noisier.
