Diesel Engine Modeling for Engine Management System Development
Licentiatavhandling, 2012

Due to increasingly strict emission legislation and stronger demands on fuel consumption, typical passenger car diesel engines become increasingly complex with more and more controllable systems added. These added systems open up for the possibility to operate the engine at more efficient conditions, but it also becomes more challenging to optimize the settings in the engine management system. One approach to handle this issue is to use a model-based strategy for engine management system optimization. This thesis describes the development and implementation of a complete diesel engine vehicle system simulation model intended to be used for engine management system optimization. The model can perform a simulation of a vehicle driving according to a predefined transient vehicle driving cycle, and it estimates the fuel consumption together with the NOx and soot emissions throughout the simulation depending on the settings in the engine management system. The simulation model is implemented in the Matlab Simulink environment, and the simulation time is in the range of 10 to 20 times faster than real-time.
