Electronic Fuel Injection System Diagram
This ensures that the fuel is well mixed with the air before it enters the chamber.
Electronic fuel injection system diagram. A modern gasoline injection system uses pressure from an electric fuel pump to spray fuel into the engine intake manifold. An electronic control unit receives information in the form of electric signals from the sensors. The fuel injection system. For a given volume of air an appropriate amount of fuel was metered into the engine by the injectors.
I have a 2004 sports car with a manual so obdii system and electronic fuel injection. Like a carburetor it must provide the engine with the correct air fuel mixture for specific operating conditions. Many diesel engines however use direct injection in which the diesel is injected directly into the cylinder filled with. Electronic fuel injection efi system use engine sensors a computer and solenoid operated fuel injector to meter and inject right amount of fuel into the cylinders.
Electronic fuel injection by dr s john alexis 2. The fuel injection system in petrolengined cars is always indirect petrol being injected into the inlet manifold or inlet port rather than directly into the combustion chambers. It is not magic although it is a complex system. Our folks have several options from basic to completely trick.
The electronic fuel injection system is a new innovation in gasoline engine this system incorporates electronic computerizm to get the best fuel and air comparisons under all engine conditions. If the ecu has control over the fuel lines then it is referred to as an electronic engine management system eems. 5 block diagram of electronic fuel injection system the sensors continuously detect the values of numerous parameters like air pressure air temperature throttle angle air density fuel temperature fuel pressure oil pressure coolant temperature exhaust temperature crankshaft angle timing engine rpm speed etc. This video is the working principle animation of electronic fuel injection system.
The efi system basically has the same diagrams as conventional fuel systems. We reach almost all horsepower endeavors. Before ecus air fuel mixture ignition timing and idle speed were mechanically set and dynamically controlled by mechanical and pneumatic means. Fitech fuel injection has been supplying automotive products specifically fuel injection products since 2012.
Really really stupid question. It gives the clear idea about how to work a fuel injection system. However the efi system does not equip with carburetor. Early 22re engines found on 1983 84 celicas used an analog system.
