Abstract

One approach to realize spark ignited (SI) engines with very low fuel consumption is to use small displacements and boosting. For several reasons conventional turbochargers are not the best choice for such systems. Instead, pressure wave superchargers offer the potential for very fast and accurate load control. In this paper a control oriented model of such an engine system is presented. The model validation is described and the main nonlinearities are identified. Using this model, a suitable control structure is derived and verified by both simulations and measurements
