Abstract

Le moteur comporte au moins un cylindre dans lequel se déplace un piston délimitant une chambre de combustion et un carter, au moins une ouverture d'admission d'air frais dans la chambre de combustion communiquant avec le carter, au moins une ouverture d'échappement de gaz brûlés dans la chambre de combustion et un dispositif d'injection pneumatique. Le carburant est pulvérisé et injecté dans la chambre 2 en utilisant un gaz comprimé. Pour les faibles charges du moteur, on utilise un gaz comprimé provenant uniquement de la chambre ou du carter du cylindre du moteur et pour les fortes charges du moteur, de manière additionnelle, un gaz comprimé provenant d'une source extérieure au cylindre. La source extérieure au cylindre peut être constituée par un compresseur mécanique entraîné par le moteur (ou un turbo-compresseur) de préférence à deux étages.
