Abstract
This paper presents a control-oriented model of a common-rail diesel engine equipped with a variable geometry turbocharger and an exhaust gas recirculation valve. The complete diesel engine model consists of two main parts: a simplified combustion process which describes the energy and torque production and a variable geometry turbocharger.
A crank-angle based cylinder-by-cylinder model of a common-rail diesel engine is used to derive the simplified model of the combustion process. The control-oriented model of the variable geometry turbocharger is based on a thermodynamic approach. The complete engine model is validated with stationary and transient measurements and constitutes the basis for the design of diesel engine control algorithms.
