Summary:

Today's engine management systems for SI engines consist of static and dynamic control algorithms. The static functions of the engine management guarantee the correct stationary operation of the engine in all the possible operating points. The static functions are contained mainly in two lookup tables, one for the spark advance and one for the metered depending on engine speed and load. Usually these lookup tables are determined with experiments on the engine test bench. In this paper, a model-based method for the evaluation of the fuel-optimal maps for spark advance and metered fuel is described.The method can be divided into several steps:The method has been tested with a BMW M30 engine (3.4 liter 6-cylinder) on a dynamic test bench. The results show that very few experiments yield good starting values for the fuel-optimal calibration of the engine. They prepare the way for further optimisation work on the test bench which now can focus on a rather narrow region around the optimum
