Abstract
Mean value engine models (MVEM) can be considered the standard models for hardware-in-the-loop (HIL) test systems for engine control units (ECUs). Mainly due to stricter environmental regulation, future ECUs for Diesel engines will also be equipped with in-cylinder pressure sensors. HIL test systems therefore have to provide the in-cylinder pressure in real time by means of a corresponding model. The paper describes extensions to an MVEM implemented in Simulink in order to calculate the in-cylinder pressure and temperature by means of appropriate heat release functions. Some emphasis is placed on the comparison of different heat release functions with respect to their applicability in real-time, closed-loop simulations. Some first steps in the calibration/parameterization of the chosen model based on real dynamometer measurements, along with a test on a real ECU, will complete this contribution.
