Abstract

L'invention concerne un système d'allumage-combustion amélioré pour des moteurs à combustion interne. Dans une zone (4) restreinte comprise dans la chambre de combustion, se situant principalement dans la culasse (6), sous une soupape (8) d'échappement, de larges effets (124a, 124b) de chasse d'air se forment sur le bord de la zone de combustion et produisent des flux (2, 2a, 3a, 3b) d'air entrant en collision les uns avec les autres, produisant une turbulence (3c) élevée au centre de la zone de combustion. Une ou deux bougies (12a/118, 12b/18a) sont placée au bord de la zone de combustion à l'intérieur des régions à effet de chasse prononcé, ce qui permet de réaliser un système combiné d'allumage et de combustion à décharge d'allumage couplée aux flux entrant en collision (colliding-flow-coupled-spark discharge :CFCSD). L'allumage est effectué au moyen d'étincelles d'allumage haute énergie résistant aux flux d'air, qui se déplacent sous l'influence de l'effet de chasse en direction de la région de turbulence centrale lorsque le piston s'approche du point mort supérieur, ce qui provoque une combustion rapide et complète des mélanges de RGE pauvres et riches et permet d'assurer un rendement maximal du moteur et des émissions minimales de gaz.
