ECU Oriented Simplified Diesel Engine Model

In this study, a four-cylinder simplified diesel engine model has been developed with a model-based design approach. In the modeling of the diesel engine, the signals coming from and going to the ECU are taken as basis. The injection time coming from the ECU and the duty cycle of the high pressure fuel pump are the main inputs. The outputs of the diesel engine model to the ECU are the rail pressure, crank and cam signals generated according to engine speed. Measurement-based simplifications were used in creating the model. The model was created in the Simulink environment. It has been observed that the outputs obtained by simulation of the model created are similar to the results obtained in real engines and other experimental studies.
