Abstract

Electronic Fuel Injection (EFI) system are part of engine fuel system and it is controlled by the engine Electronic Control Unit (ECU) management component that is found on the vast majority of road transportation either it is passenger or commercial vehicles. The fuel injectors act as the nozzles that spray the fuel into the engine in specific patterns and at specific timed intervals that will optimize engine performance. The electronic fuel injector specific timed intervals operations are controlled by the engine ECU. As a part of the fuel system, any problems with these components can cause all sorts of engine performance issues and may lead to engine terminal failure if the problems lead to become more worsen and neglected by vehicle owner. In local automotive service industry and learning institute nowadays, automotive service technician usually taking conventional troubleshoot approach when dealing with faulty electronic fuel injector. The technician usually take a conventional approach where they use screwdriver method to diagnose whether the electronic fuel injector is produce pulsating reaction at it nozzle when spraying fuel inside the combustion chamber or not. This conventional method is done by place the tip of the screwdriver on the fuel injector body while hearing by using their ear at the other end of the screwdriver. This conventional method however are no giving accurate results as other external interference such as from engine vibration may cause an interference in this procedure. Besides, the electronic fuel injector spray pattern from it nozzle may not be able to be analyse as the fuel injector is not being taking out from the fuel rail. Therefore, the purpose of this research is to design and analyze electrical circuit of electronic fuel injector tester for education purpose that would simulate the electronic fuel injector system operation such as open and close it plunger valve in specific timed intervals. The design and analysis will be done by using National Instrument (NI) circuit design suite Multisim and Ultiboard software version 12.0. The simulation is analyzed based on the voltage reading, current output besides signal's voltage over time graph that can be acquired by using a virtual oscilloscope that were provided in the NI Multisim software analysis tool application before being transfer to NI Ultiboard for Printed Circuit Board (PCB) layout.
