Even if hybrids seem to be the media friendly solution, there is still much work to be done on combustion systems. For gasoline engines aggressive downsizing seems promising and IFP proposes an innovative approach. However, new difficulties arise as specific power outputs are increased. Various combustion phenomena are encountered from simple knock to rumble and must be understood and mastered in order to fully optimize the combustion system. Abnormally rapid yet non destructive and seemingly stable combustion is one of these new phenomena. 3D CFD (Computational Fluid Dynamics) simulation tools were used in order to investigate and under- stand what lies behind this particular combustion. 3 Oil and Gas Science and Technology 64 ARTICULO Réveillé, B. 41732 Duparchy, A. 41733 170260 170260 0 0 0 0 238079 BAAB BAAB 2026-03-05 200045087 0 200045087 2026-03-05 15:12:31 2026-03-05 ARTICULO
