ON THE POSSIBILITY TO ASSESS POLLUTANT EMISSIONS OF A DIESEL ENGINE BY APPROXIMATION FUNCTIONS

Autor/autori: Bogdan Radu, Alexandru Racovitza,*, Radu Chiriac


Abstract: Controlling the emissions is extremely important nowadays. In terms of engine operation, the actual engine control units allow the rapid adjustment of the values for many parameters governing the processes inside the cylinder. The effective measurement of emissions is on the contrary a slow procedure, depending on many variables and featuring a limited precision. Therefore, a group of approximation functions based on the most sensitive factors could be more effective and preferable for combustion process control. The proposed paper is offering an analysis of such functions, using experimental data and results obtained by advanced modeling programs. Finding certain methods to adjust the combustion for reaching desirable efficiency and emissions results represents also another goal of the presented work.
