Educational application used to simulate the functionality of a Gasoline Injection System

Abstract

This paper presents an educational application, with practical realization, regarding the functionality simulation of a gasoline injection system using a computer and a peripheral afferent, along with its control circuit. The application replaces the ECU (Engine Control Unit) and controls a demo injection rail, equipped with four gasoline injectors with different shapes of flow. The equipment provides the flow shape visualisation and injection parameters change according to the engine load conditions, which can be simulated by the electronic equipment through the virtual interface. The system allows the determination of the gasoline amount injected by the various types of fuel injectors, in a certain period of time and at different pressures of the fuel, depending on the load and the speed of the engine.
