Engine simulation has traditionally been an instrument for the early phase of engine design in order to choose the optimal compromise between the different requirements, such as cost, packaging, performance and fuel consumption. However, the problem has somewhat changed from an engine design to an engine calibration and function development task, as new technologies increase the degree of freedom to such an extent that it is almost impossible to find the optimal setting in the test bench. The purpose of the model is to be used as a Model-In-the-Loop model for offline simulation and debugging during the algorithm development phase of the engine controller. It can also be used during the rapid prototyping calibration phase as the amount of measurements needed for the model is relatively small. From the measurements, simulation can rapidly be executed to find a calibration setting which is in the correct ballpark.
