The diesel engines are compression ignition. It have very fine fuel nozzles.

Can we use petrol in diesel engine? why?

We can't use petrol in diesel engines because diesel engines are designed for high torque at low speeds.

This is not an exact answer because during the injection to the combustion chamber, the fuel mixture will be at high pressure and temperature. We know that pressure is directly proportional to temperature, so it gets ignited.

You are right madam.
Because it is work at diesel cycle.
Because it is work at diesel cycle.

It's not the correct answer because fuel is ignited because of high pressure generated on compression which in turn produces temperature.

If pressure increases then temperature also increases due to this high temperature the fuel is ignited.

Petrol engine ignition temp are high but diesel engine ignition temp are low. So, OPTION B is correct.

@Mahur.
Petrol engine are temp high per diesel engine is DON'T temp so Answer is A not b.
Petrol engine are temp high per diesel engine is DON'T temp so Answer is A not b.

Due to the high degree of compression fuel achieves itself ignition temperature. And combustion starts.
