Abstract


Present paper aims to optimize performances obtained in case of a spark-ignition engine by reducing both fuel consumption and pollutant emissions. Therefore, the study has three parts begining with a theoretical optimization of engine functioning for an Audi A6 motor vehicle, by using a program developed in Matlab20a. Follow-up, optimized data have been used to simulate pollutant emissions with the use of a different programming software. There have been taken into account all functional, geometrical and of performance parameters in order to
conduct a real simulation. In the final analysis, simulated data from experimental tests and after applying PID controller have been saved separately and used to plot results in form of graphs, also in Matlab20a software.
