Performance of Electronic Governor and Embedded Systems for Locomotive Operation

Abstract

The performance of diesel engines is heavily influenced by their injection system design. In fact, the most notable advances achieved in diesel engines resulted directly from superior fuel injection system designs. While the main purpose of the system is to deliver fuel to the cylinders of a diesel engine, it is how that fuel is delivered that makes the difference in engine performance, emissions, and noise characteristics. The objective of the present work is to evaluate performance of a system that contains electronic control using embedded system and engine with Electronic Control Module (ECM), comparing it with other system operated with mechanical governor. The content and function of each system have been discussed. The efficiency of the electronically-controlled engine has been verified using MATLAB software. According to simulation results, electronically-controlled engine give the better performance and less fuel consumption compared to mechanical governors based-system.
