Performance of Electronic Fuel Injection System Using Compressor and Controller

Abstract

This paper studied about by using air compressor instead of fuel pump in which the petrol is pressurized by the compressed air which is sent to the fuel tank and the fuel comes out from the fuel tank through the regulating valve and it is directed towards the fuel injector. The fuel injector is controlled by using micro-controller and TPS (Throttle position sensor) which is mounted on the throttle body. The fuel eventually evaporatedin the inlet port by velocity spray which is created by the injector by pulsating needle, which receive the signal from the micro-controller. Here, the effort is made to make the system in which, the compressor is only running to create a necessary pressure range and then reaching to its maximum range, it is shut-off during the engine running. When the petrol level and pressure in the fuel tank decreases to the minimum value, the compressor is start again. The working of fuel pump is totally eliminated. Bythis system, during the time interval between shut off to start point of compressor, we can save the available power of an engine which earlier continuously used to drive the fuel pump
