Abstract: In the Modern world, automotive electronics play an important role in the manufacturing of any passenger car. Automotive electronics consists of advanced sensors, control units, and “mechatronic“actuator making it increasingly complex, networked vehicle systems. Electronic fuel injection (EFI) is the most common example of automotive electronics application in Powertrain. An EFI system is basically developed for the control of injection timing and fuel quantity for better fuel efficiency and power output. In this paper, we will explain various types of fuel injection system that are used most commonly nowadays and will also explain the various parameters considered during calculating,(using speed density method), base fuel quantity during runtime. We will explain the major difference between speed density method and alpha-n method and in the end, we will also show the MATLAB/Simulink model of fuel injection system for Single cylinder four stroke engine.

Keywords: Air Fuel Ratio, Fuel Injection System, Speed Density Method, Engine Management System
