A Study on Advance Electronic Fuel Injection System

This paper describes advanced fuel injection system for small vehicles which have recently become commercially available. system have been designed and developed by the authors’ organization. This system called electronic fuel injection (EFI) use electrical and electronic device to monitor and control engine operation. An electronic control unit (ECU) or the computer receives electrical signals in the from of current or voltage from various sensors. The fuel injection pump is driven by an electric motors the pressure control valve regulates the pressure at 100 bar and the calibration fluid is injected through the nozzle into the measuring Cylinder. For the analysis fuel is injected to the virtual conical jar made at the bottom of injector. Fuel consumption and emission result from system are present, and in case it is shown that engine out exhaust emission meet current and future in Europe, India and Taiwan without the need for exhaust after treatment. It is also shown that system offer significant fuel saving relative to otherwiseequivalent, carbureted baseline vehicles. The paper also includes a short overview of the performance and cost implication of system relative to alternative emission control methods.
