fuel injection system in petrol engine ( Telugu lecture). or fuel system in spark ignition engine.

MAIN COMPONENTS OF FUEL INJECTION SYSTEM:
FUEL TANK
FUEL FEED PUMP
FUEL FILTER
AIR FILTER
CARBURATTOR
SPARK PLUG
WORKING PROCESS: In this the fuel from the fuel tank enters the fuel feed pump . In fuel feed pump the pressure of the fuel is increased . Then the fuel is enters into the fuel filter where all the dust particles are removed. From the filter the fuel enters into the Carburettor. The air enters through the air filter to carburettor. In air the dust particles are removed by air filter. The filtered air is enters to the caeburettor. The homogeneous mixture of air and fuel is prepared in the carburettor and the fuel mixture is supplied into engine cylinder during suction stroke. this topic is very important for diploma mechanical ,electrical, and engineering,I.T.I and general students
