Modelling of high Karlovitz combustion in spark-ignition engines

Edouard Suillaud as a PhD student at IFPEN studied how to better describe the combustion in high Karlovitz1 number regimes such as those encountered in the new combustion chambers of spark-ignition engines. This description was limited by models that were not suitable for such regimes. The extension of the CFM model to “thin reaction zone regime” (TRZ) has produced promising results.

Internal combustion engines

Since they were invented, cars have mainly operated with 4-stroke internal combustion engines. In Europe, these have either been gasoline (spark ignition) or diesel engines. Major technological progress has made it possible to increase the efficiency of IC engines in order to save fuel and significantly reduce associated pollutant emissions
