Abstract

Certains modes de réalisation de la présente invention concernent un procédé pour faire fonctionner un moteur à allumage par compression (CI). Le moteur CI peut comprendre une chambre de combustion. Le procédé pour faire fonctionner le moteur CI comprend la réception d'un volume de charge d'admission dans la chambre de combustion, la compression de la charge d'admission, l'injection d'un volume de carburant dans la chambre de combustion, le carburant ayant un indice de cétane inférieur à environ 40, et la combustion de sensiblement la totalité du volume de carburant. Un délai entre l'injection du volume de carburant dans la chambre de combustion et l'amorçage de la combustion est inférieur à environ 2 ms. Le moteur CI comprend au moins un moteur à deux temps, un moteur à pistons opposés, un moteur à pistons opposés à deux temps, un moteur à cinq temps, un moteur à six temps, un moteur à pistons libres, un moteur à pistons libres linéaire, un moteur rotatif et/ou un moteur rotatif Wankel.
