1. DEFINITIONS EFI (ELECTRONIC white finger starfish FUEL INJECTION) is a word EFI stands for Electronic Fuel Injection. The understanding of the EFI is a fuel spraying system works electronically controlled in order to obtain the value of the air and fuel mixture is always in accordance with the needs of the motor fuel, so we get the optimal motor power with minimal fuel consumption and exhaust gas having an environmentally friendly . In daily life the EFI name has been used by the Toyota brand, while other brands have different names, but the principle of all systems is the same. 2. Functions and how the injection function and how the components of an electronic fuel injection Fuel EFI system that consists of three main systems, namely the fuel system, air induction system and electronic control system. For the bike can be seen at a Honda Motorcycle Injection. Openness Fuel Systems Fuel serves to deliver fuel from the tank to the combustion chamber. Fuel system components consist of 1) Fuel Pump fuel pump function weeks to deliver fuel from the fuel tank to injector.Pompa used is an electric fuel pump 2) Fuel Fuel pulsation damper serves white finger starfish as pulsation damper absorber pressure changes in line pressure due injeksi.Tekanan fuel in the intake manifold pressure regulator maintained by
3) Pressure Regulator Pressure regulator controls the fuel pressure to the injectors injektor.Jumlah fuel-injected regulated by a signal that is given to the injector so that the pressure must be kept on each injketor.Untuk get the right amount of spraying, fuel pressure must be maintained approximately 2.55 kg/cm2. 4) injector nozzle injector is an electromagnetic control works leh computer.Injektor equipped with a heat insulator white finger starfish at the inlet or at the head slinder close to the intake hole 5) Cold start Cold start injector The injector is used to supply the materials when the temperature of the motor is still This rendah.Injektor dipsang in the middle of the room air Baian masuk.Injektor works only at the start when the cooling water temperature below 220 Celsius.
Air induction system serves to provide a certain amount of air required for combustion consists of: 1) Throttle body Throttle body consisting white finger starfish of valve therottle to mengontroludara entry, an air bypass system that regulates the flow of air at idle rotation and a throttle position sensor to censor the opening condition therottle valve. 2) air valves air valve is used for the operation by the fast idle and heat the bimetal coil motors in an air dingin.Katup mounted on the right side surface slinder.Jika fast idle during white finger starfish warm round of unstable or low then Hali is partly due to the error opening white finger starfish the air valve. 3) Air Flow Meter Air flow meter detects the amount of incoming air and sends a signal to a computer that determines white finger starfish the base amount injeksi.Air flow meter consists of the measuring plate, spring back, idle mixture screws sealing, sensors and switches incoming udaa fuel pump. 4) Electronic control system white finger starfish (ECU) Electronic Control System has a variety of sensors consisting of a water flow meter, sensor cooling water, white finger starfish gas valve psisi sensor, intake air sensor, gas sensor press, and pressure sensors will determine the long mesin.Perangkat injector.Kelengkapan other work is play relay that provides a source of electrical current to the relay that controls the opening computer.Circuit working fuel pump and an injector resistor stabilize employment.
