AN OVERVIEW OF ELECTRONIC FUEL INJECTION SYSTEM

MECHANICAL ENGINEERING

This paper gives an overview of electronic fuel injection systems for small automobiles currently available on the market. Electronic fuel injection (EFI) is a technology that monitors and controls engine functions using electrical and electronic devices. Electrical signals in the form of current or voltage received by an electronic control unit (ECU) or a computer from numerous sensors. An electric motor drives the fuel injection pump, the pressure control valve keeps the pressure at 100 bar, and the calibration fluid has injected into the measurement cylinder through the nozzle. Fuel is delivered into a simulated conical jar at the bottom of the injector to conduct the analysis. It is also illustrated that the system saves a large amount of fuel compared to similarly equivalent, carburetted automobiles. This paper provides a review of the system's advancement over the last two decades and explains the need for a more advanced fuel injection system for improved fuel efficiency, fuel management, and lower carbon emissions.
