Integration of a Modal Energy and Emissions Model into a PNGV Vehicle Simulation Model, PSAT 2001-01-0954

This paper describes the integration of a Modal Energy and Emissions Model (MEEM) into a hybrid-electric vehicle simulation model, the PNGV System Analytic Toolkits (PSAT). PSAT is a forward-looking computer simulation model for advanced-technology vehicles. MEEM is a vehicle fuel-consumption and emissions model developed by one of the authors for internal-combustion-engine (ICE) -powered vehicles. MEEM engine simulation module uses a power-demand physical model based on a parameterized analytical representation of engine fuel and emissions production. One major advantage of MEEM is that it does not rely on steady-state engine maps, which are usually not available for most production vehicles; rather, it depends on a list of engine parameters that are calibrated based on regular vehicle dynamometer testing. The integrated PSAT-MEEM model can be used effectively to predict fuel consumption and emissions of various ICE-powered vehicles with both conventional and hybrid power trains. This paper also presents a methodology used by MEEM to generate simulated engine maps based on vehicle dynamometer testing. For illustration purposes, engine performance maps of a model year 1997 (MY97) Taurus engine and a model year 1999 (MY99) Toyota Prius Atkinson-cycle engine generated by MEEM are presented.
