Abstract

[Problème] L'invention vise à concevoir un moteur à combustion interne approprié pour un système hybride et en mesure d'empêcher une réduction de la puissance à vitesse moyenne/élevée ainsi que du couple, en mesure d'améliorer la consommation de carburant, et en mesure de réduire la charge environnementale en réduisant le réchauffement climatique, par exemple. [Solution] Lors d'une course d'admission, un piston (14) à l'intérieur d'un cylindre (1) descend, une soupape d'admission (20) s'ouvre, et de l'air est aspiré dans le cylindre (10). Cet air aspiré est comprimé par un compresseur d'alimentation externe (80) et refroidi par un dispositif de refroidissement (90), et le volume d'écoulement est ajusté par un mécanisme d'accélérateur (70). Lors d'une course de refoulement dans la chambre de mise sous pression, le piston (14) se soulève, une soupape de refoulement (40) de la chambre de mise sous pression s'ouvre, et l'air sous pression est acheminé jusque dans une chambre de mise sous pression (60). Lors d'une course d'admission dans la chambre de mise sous pression, le piston (14) descend et une soupape d'admission (50) de la chambre de mise sous pression s'ouvre, pour ainsi aspirer l'air sous pression dans le cylindre (10) à nouveau à partir de la chambre de mise sous pression (60). Subséquemment, une course de compression, une course de combustion, et une course d'échappement, qui sont identiques à celles dans un moteur à combustion interne à quatre temps, se produisent.
