Development and validation of an MVEM from an SI-engine based WCCM

Abstract

Mean Value Engine Models (MVEM) model the averaged dynamics of an automobile engine and have been used for the purpose of automotive control and fault diagnosis. Within-Cycle, Crank-Angle based Models (WCCM) are complex models that model the instantaneous dynamics of engine states and replace a real engine for simulation purposes. A WCCM was constructed on the simulation platform AMESim™. An MVEM was derived from this simulation data. The motivation for this work was to use this model in an MVEM based Fault Diagnoser
