Why a turbocharger is not used in a petrol engine?

They certainly are. Using them together with carburetted engines can be a bit tricky, and usually the compression has to be lowered when compared to a naturally aspirated 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.


Effect of gearing ratio on fuel consumption?

Gear ratios will let the engine run at the speed and load at which it is most efficient, which is good for low fuel consumption and an exhaust that is as clean as possible.


What is an aircraft engine?

What causes a jet engine to ignite?

A Jet engine contains a series of turbines that accelerate the air that enters the engine. As the air is accelerated it is compressed to a higher density at which point the fuel is able to begin combustion at ambient temperatures. As the engine warms it becomes more efficient as the fuel is pee heated and the compressor is able to spool faster. At higher altitudes the engine becomes more efficient as the initial air density is lowered causing less resistance on the turbines to accelerate the air, thus allowing a higher spool rate with less fuel. Jet engines are very inefficient at sea level when compared to their efficiency at cruising altitudes.
