A Study of Fuel Injection Systems in Diesel Engines

Abstract

The authors show their analytical model of the fuel injection system in a diesel engine. In the first part, the authors initially describes the model assumptions, classification of injection phenomena, and fundamental equations considering the compressibility, inertia and viscocity of hydraulics and the movements of valves and other components to improve the accuracy of the systems. Secondly regarding the experimental constants and physical properties of the fuel, the authors show the method of selection they used to simplify the analytical model and to get good agreement as a result but without losing physical meanings.
