PETROL ENGINE

PETROL ENGINES:

PETROL ENGINE

               Petrolengines are the most commonly using engine in the world,because petrol engines are most efficient and it has noiceless working.Petrol engines also has a cylinder and a piston.A carburator is must for this petrol engines.Carburator is used to mix air with petrol.The air and petrol mixture is used as the fuel in petrol engine.In the top of the cylinder there is a inlet and outlet valve,the air petrol mixture will enter into the cylinder through the inlet valve.Through the compression stroke the mixture will compressed by the piston,and it will burned by sparkplug.The sparkplug is the important particle in the petrol engine,it is used to make electricspark in the engine cylinder.This electric arc is produced by a external battery or something.After the ignition stroke the burned fuel will goes out through the outletvalve in exhaust stroke.The vehicles using petrol engines has higher efficiency and milage.So the petrolengines are widely used.

ADVANTAGES:
          >It is more efficient
          >It has noiceless working
          >More compact in construction
          >Fuel efficiency is high
