PC Based (Digital) Controlled Gasoline Fuel Injection System For a Single Cylinder Spark Ignition Engine

In this paper the experimental investigations relating to the performance and emission characteristics of a single cylinder spark ignition engine operating on a newly designed gasoline fuel injection system is described. This gasoline fuel injection system was operated under port injection configuration by controlling the duration of injection with PC based control system, which uses the information corresponding to engine speed and throttle positions. A comparison between the manually controlled version had indicated that the overall performance of the PC based fuel injection system is better than that of the manually controlled system fuel injection system.
