A diesel engine is an internal combustion engine which uses the heat of compression to ignite the fuel/air mixture in the third stroke of the 4-stroke cycle, while the petrol engine is an internal combustion engine which uses an electrically-generated spark system to do the ignition.

Diesel engines have a higher efficiency compared to petrol engines. In simple terms this means diesel engines can give 50% or more miles per gallon than petrol engines.

What is diffrent between a 5.7L hemi diesel engine and a regular diesel engine or a petrol engine?

There isn't a 5.7L Hemi diesel.


Can you make a diesel engine which works on the basic principle of petrol engine or you can say it uses diesel as a fuel but works on the principle of petrol engine?

No, a diesel is a compression firing engine and a petrol is a spark firing engine. Diesel fuel will not burn in a petrol engine with spark plugs.


Why compression ratio of petrol enine is 8 where as diesel engine is 22?

because a diesel engine ignites its fuel with pressure, and not with a spark like a petrol engine. that is why a petrol engine does not need as high a compression ratio as a diesel engine


What are the defferences between dessel and petrol engine?

Petrol & Gas engines are spark ignited engines where as diesel engines are compression ignited engines. Petrol engines works with explosion of fuel air mixture due to spark from spark plug inside the cylinder. Diesel engines works with combustion of fuel air mixture due to compression, compressed mixture attains a very high temperature which exceeds the flash point of diesel and starts burning inside the cylinder and the hot gases after burning of fuel misture exerts force on piston which makes the diesel engines work. Diesel engines are highly efficient than petrol engines.


How can you convert petrol engine in into diesel engine?

You can convert a petrol engine into a diesel engine by changing the fuel injectors. The fuel filters will also need to be changed.

How do you distinguish between a petrol engine and diesel engine when they are not working?

If the engine has spark plug it is said to be petrol engine, and if it has a pump to inject fuel then it is diesel engine.

Which has a highest starting ignition between petrol n diesel?

Diesel has highest ignition temperature.. So only diesel cant be used in petrol engine


Is it possible to use diesel in petrol engine?

No. A petrol or gasoline engine will not run on diesel fuel.


Why cant petrol be used in diesel engine?

Because one has a petrol engine and the other has a diesel engine. Petrol/gasoline does not ignite the same way as diesel. It also does not have the lubrication qualities that diesel has. Gas in a diesel engine will damage the fuel system if the diesel very quickly.


What is the major difference between a petrol car and a diesel one?

The primary difference between a petrol car and diesel car is the consumption rate - diesel and petrol are refined from mineral oil using differing methods. The result is diesel engines having a lower fuel consumption rate than their petrol counterparts when installed in a vehicle of similar mass. CO2 emissions are also lower in a diesel engine than they are in a petrol engine.
