Function and work of Injection Machine

Function and work components of gasoline electronic fuel injection
EFI system that consists of three main systems, namely the fuel system, air sinduksi systems, and electronic control systems.a. Fuel SystemFuel system serves to distribute fuel from the tank into the combustion chamber.Fuel system components consist of1) Fuel PumpUtuk functioning fuel pump delivering fuel from the tank to the fuel used injector.Pompa is electric fuel pump2) Fuel pulsation damperFuel pulsation damper serves as an absorber pressure changes due to pressure on the channel injeksi.Tekanan fuel in intake manifold pressure is maintained by the regulator
3) Pressure RegulatorsPressure regulator serves to regulate the pressure of fuel-injector injektor.Jumlah inject fuel at regulated by the signal given to the injector so that the pressure must remain on each injketor.Untuk get the right amount of spraying, fuel pressure must be maintained more or less 2.55 kg/cm2.4) injectorIs an electromagnetic injector nozzle that controlled his computer.Injektor Leh equipped with heat insulation on the inlet or at the head close to the hole slinder income5) Cold start injectorCold start injector is used to supply materials at the temperature of the motor is still rendah.Injektor Baian dipsang in the middle of the room air masuk.Injektor work only at the start when the cooling water temperature below 220 Celsius.
b. Air induction system serves to provide a number of air needed for combustion comprising:1) Therottle bodyTherottle body composed of valve therottle to mengontroludara entry, a system that regulates the air passes by air flow at idle speed and a position sensor therottle to censor therottle valve opening condition.2) Air ValvesAir valve in use for fast idle operation of the bimetal coil motors and heat in the air dingin.Katup attach conditions on the surface of the right side slinder.Jika fast idle during warm-up lap is unstable or low, Hali was caused by an error opening the air valves .3) Water flow meterWater flow meter to detect the amount of air entering and sending a signal to a computer which determines the basic amount of injeksi.Air flow meter consists of the measuring plate, spring back, the idle mixture screws insulation, sensors and switches udaa incoming fuel pump.4) Electronic Control System (ECU)Electronic Control Systems has a variety of sensors which consist of water flow meter, coolant water sensor, the sensor psisi gas valve, air intake sensor, press the gas sensor, and pressure sensors will determine the long mesin.Perangkat injector.Kelengkapan other work is play relay which provides a source of electric current to computer.Circuit opening relay which controls the fuel pump working and working to stabilize an injector resistor.
