Fuel injection system the fuel injection pump starts. A computer model simulating the flow in fuel injection systems has been used in order to investigate the fuel injection processes in an inline pumpbased fuel injection system for direct. Understand the function and operation of governors and fuel system. As this electronic fuel injection system diesel engine, many people afterward will need to purchase the collection sooner. The following characteristics of an injection system are desirable in achieving these goals. The main difference between carburetor and fuel injection system carburetorzfuel is atomized by processes relying on the air speed greater than fuel speed at the fuel nozzle, zthe amount of fuel drawn into the engine depends upon the air velocity in the venturi fuel injection systemzthe fuel speed at the point of delivery is greater than the air speed to atomize the fuel. Pdf flow in fuel injection systems for di diesel engines. Injection pressures during the whole process should be above 1200 bar for a good spray formation and air fuel.
