Abstract
This paper presents a control-oriented mean value model of a Spark-Ignition (SI) engine supercharged with a Pressure-Wave Supercharger (PWS). The model of the PWS is based on linear gas dynamics. It is part of an overall engine model which predicts conditions in the intake manifold such as pressure, tem-perature, and exhaust gas recirculation rate (EGR), as well as the states in all the other receivers. The model is validated by steady-state and transient measurements on a highly dynamic engine testbench.
