Torque Model Calibration of a Motorcycle Internal Combustion Engine

Optimizing the performance of internal combustion engines increases complexity of control strategies and makes the calibration process long and expensive. The first activity of this Thesis explains the possibility of reduce tests on the bench saving in terms of working hours and operating costs. In particular, through MATLAB codes, it’s shown how extrapolating data of spark advance min and extramin from the spark advance dynamic sweep. The tests are usually demanded by the ECU supplier, who is responsible for the final calibration, but the calibrator engineer still has the task of checking the work of the supplier. For this reason the second activity of this Thesis was to create a simplified Torque-based model that determines the behavior and response of the engine (R2 = 0.98). Cases of study are explained in details and various simulations are realized.
