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.

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.
What are the difference between petrol engine and mpfi engine?
There is no difference. Petrol is just another name for gasoline. MPFI just means Multi-Point Fuel Injection. A petrol (gasoline) engine can be MPFI or it can have a carburetor. It can have many different ways to get gasoline (petrol) to the cylinders.
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
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.
What is the difference between a petrol engine and a gasoline engine?
A petrol engine and a gasoline engine are the same thing. The latter is the term used in the United States, while the former is used in the United Kingdom.
How petrol engines function?
WHAT ARE THE BASIC PARTS OF PETROL ENGINE? HOW DOES PETROL ENGINE WORKS?
