The EFI system of an automobile engine is generally composed of three parts: a fuel injection circuit, a sensor group, and an electronic control unit. If the injector is installed in the original carburetor position, ie the entire engine has only one petrol injection point, this is a single-point EFI; if the injector is installed on the intake pipe of each cylinder, ie the injection of gasoline is from multiple places (At least one injection point per cylinder) is injected into the cylinder, which is the multi-point EFI.
Cummins is the world's largest
independent engine manufacturer, including diesel and fuel engines, engine key
components (fuel systems, control systems, intake air handling, filtration
systems and tail gas treatment systems) and power generation systems.
