1. Combustion modeling

Since the 1960s-1970s, mathematical modelling of internal combustion engines and simulation of their operation have developed considerably. This approach, which complements the traditional experimental approach, is primarily aimed at reducing specific fuel consumption and pollutant emissions .

Various types of mathematical model can be used to simulate the operation of internal combustion engines, whether spark-ignition or compression-ignition. These models can be grouped into two main categories: control-oriented models and physical models (figure
