Electronic Fuel Injection System Diagram and Working Principle

Electronic Fuel Injection System Diagram and Working Principle

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. The EFI system basically has the same diagrams as conventional fuel systems. However, the EFI system does not equip with carburetor. Instead, the injector will be placed in front of the intake valve in each cylinders. Then how about the diagram of electronic fuel injection ? below we will learn a basic schematics of EFI system for you to understand easily. A. Fuel Line diagram of EFI system As seen above, the efi system has a fairly simple diagram of fuel lines. The fuel will be moved directly from the tank to the injector. The flow of gasoline in the EFI system is more like this, Gasoline inside the tank will be pumped by an electric pump located inside the tank (sink). Gasoline from the pump will flow through the fuel filter. In the fuel filter, the gasoline will be filtered from any dust or d…
