Transient Performance Prediction of Diesel Engine and Turbocharger Using Phenomenological Diesel Combustion Model

Abstract

A phenomenological diesel combustion model has been developed. This model is able to predict a heat release rate in a good accuracy for various operating conditions. The combustion model is implemented into one dimensional fluid dynamics simulation to predict the diesel engine transient performance taking turbochager response into account. The combustion control and designing turbocharger concept for improving a transient performance are studied using engine and turbocharger simulation.
