What are the basic different between the petrol and diesel engine?

Well gasoline engines have a spark plug that ignites the gasoline as it is injected into the engine. Diesel engines have no spark plugs because the high compression ignites the fuel as it is injected. Because it releases higher energy density, diesels get better fuel economy.
The main difference between a diesel and a gasoline (petrol) engine are the way the fuel is ignited. In a gasoline engine, a fuel/air mixture is introduced into the cylinder either through a carburetor or fuel injection system, where it is then compressed and ignited with a spark. In a diesel engine, air is compressed in the cylinder which heats it to about 1000 degrees F (550 degrees C), then fuel is injected under high pressure and ignited by the superheated air. To accomplish this, diesel engines also have higher compression ratios than gasoline 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
Why petrol csnnot be used in diese engine?
The diesel engine is designed to use diesel, which reaches combustion at high (relatively to petrol) pressure and temperature. If petrol is injected into a diesel engine, then combustion will take place in a, very different than it was designed, way, which will eventually destroy the engine. But there are engines that have been designed to burn diesel or petrol. They call them bifuel engines. Old farmer tractors used to have this kind of engines.
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 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 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 petrol engine oil be used for a diesel engine?
No it cannot. Petrol and Diesel are different.
What is the different between petrol and diesel?
The difference is that diesel is more oily than petrol, and is cheaper to produce.
What happen when petrol fuel is use in diesel engine?
Petrol in a diesel engine will destroy the engine.
Why is petrol engine RPM is greater than diesel engine?
for same power diesel engine produces more torque @ less rpm whereas petrol engine produces less torque @more rpm this difference is due to different combustion processes of diesel and petrol
Is petrol is used in diesel cars?
No, diesel engine require diesel fuel. Put petrol in a diesel engine and you will destroy it.
What is the difference between the diesel engine and gasoline engine?
One runs on diesel and the other on petrol. Click the link.
Can a petrol engine be converted to a diesel engine?
No, you cannot convert a petrol to burn diesel.
Why not use petrol in diesel engine?
If you use Petrol or Gasoline in a Diesel engine you will destroy that engine. That is why you do not use it.
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.
Which has a highest starting ignition between petrol n diesel?
Diesel has highest ignition temperature.. So only diesel cant be used in petrol engine
