- Fuel SystemFunctions and how the components of electronic gasoline fuel injection or EFI system consists of two main systems fuel systems, air induction systems.
a.
Fuel system works to deliver fuel from the tank to the combustion chamber.
Fuel system components consist of:
1. Fuel Pumps
Serve fuel pump to deliver fuel from the tank to the injector. Digukanan fuel pump is an electric fuel pump.
2. Fuel Pulsation Damper
Fuel pulsastion serves as an absorber damper on the duct pressure changes due to the injection pressure. Fuel pressure in the intake manifold is maintained by a pressure regulator.
3. pressure Regulator
Pressure regulator controls the fuel pressure to the injector-injector. The amount of fuel injected is governed by a signal supplied to the injector so that the pressure must be kept on each of each injector. To get the right amount of spraying, the fuel pressure should be maintained approximately 2.55 kg/cm2.
4. injector
Injector nozzle is a multilayered work of electromagnetic controlled by the computer. Injector equipped with a heat insulator at the inlet or to the head close to the hole slinder income.
5. Cold Start injector
Cold start injector is used to supply materials at low engine temperatures. Injector is mounted in the center of the room air. Injector works only at the start when the cooling water temperature in that 220 celsius.
