Usually attached to the frame at the rear of vehicle. Separate fuel injection system is used for each cylinder which controls the mixture under different load and speed conditions.įuel tank: It is made of sheet metal. The fuel is atomized by means of a nozzle and then delivered into an air stream. Fuel injection System: In fuel injection systema fuel injection pump is used in place of carburettor. In this system the fuel tank is placed at any suitable position in the vehicle. The pump is driven either by the camshaft or electrically. Pump feed system: Fuel pump is used to feed the fuel from the fuel tank to the carburettor. Vacuum fuel feed system: The engine is used for sucking the fuel from the main task to the auxiliary fuel tank from where it flows by the gravity to the carburettor. In this system the tank is placed above or below the carburettor. The pressure is created in the tank by means of a separate air pump.įor starting, the pump is primed by cam which produces pressure in the tank and the fuel flows to the carburettor. Pressure fuel feed system: A pressure sealed tank is used.
Some gasoline engines are using fuel injection system instead of carburettor.įuel flows due to the gravitational force. The pump system is used universally on motor vehicles. Fuel Feed Systems: Gravity system Pressure system Vacuum system Pump system Fuel injection system Gravity, pressure and vacuum systems are obsolete now.
COMMON RAIL FUEL INJECTION SYSTEM PPT DRIVER
To indicate to the driver the fuel level in the fuel tank. How many types of fuel supply system in petrol engine?įunctions of fuel feed system: To store the fuel in the fuel tank To supply the fuel to the engine to the required amount and in proper condition. Components of fuel feed system for petrol engines: Fuel Tank Fuel Pump Fuel Filter Carburettor Intake Manifold Fuel lines or tubes necessary for connections Gauge to indicate the fuel in the fuel tank.
Primary difference between Carburettor and Fuel Injection system is fuel injection atomize the fuel by pumping fuel through a small nozzle under high pressure, where as in carburettor relies on suction created by intake air. Fuel supply systems are divided into two: Carburettor.įuel Injection system. Fuel supply system is used for sending fuel into Internal combustion engine.
