Abstract

This article deals with the issue of efficient fuel mixture preparation and injection control in internal combustion engines. Based on physical models a numerical model had been proposed and developed to enable simulations of the solved processes. A single cylinder engine model for transient simulations were developed using the Lotus Engine Simulation software. An engine control unit had been designed for the single cylinder engine model that controls the fuel injection dose at a certain engine load based on the information stored in the ECU. The effect of engine speed and throttle body opening on the fuel injection process was tested. Transient simulation results obtained from Lotus Engine Simulations were verified using the Matlab/Simulink software environment.
