  • ® when the engine controller turns off the operation of the middle cylinders and changes the control of the valves.
  • the first way to change the variants of valve control in the cylinder head from variant A to variant B, and vice versa, is possible by changing the cams A, marked in blue to cams B, marked in red, by moving them on the camshaft by the cams changing mechanism - CCM. This is illustrated in Fig. 3.

Abstract

La présente invention concerne un moteur à combustion interne multifonctionnel qui est un moteur à quatre temps avec ou sans turbocompresseur, à allumage commandé ou allumage par compression, qui peut fonctionner de deux manières différentes interchangeables : 1. un fonctionnement normal, en utilisant tous les cylindres, comme illustré sur les fig. 1A et 6A; 2. un fonctionnement économique, lorsque certains de ses cylindres sont mis hors tension et avec l'expansion des gaz d'échappement dans ces cylindres en provenance des cylindres fonctionnant comme sur les fig. 1B, 2C et 2D, ainsi que 6B, 7C et 7D. La pression des gaz d'échappement dans les cylindres au moment de l'ouverture des soupapes d'échappement peut même faire jusqu'à 6 bars de plus que la pression atmosphérique. Ce moteur diffère d'un moteur normal, principalement par la construction de la culasse et le paramétrage du régime. Lorsque le véhicule prend de la vitesse et lorsque la demande de puissance est bien moins importante, l'unité de commande de moteur arrête le fonctionnement de certains de ses cylindres et change la commande des soupapes. Ensuite, le moteur fonctionne de manière économique. L'augmentation attendue de l'efficacité peut atteindre 15 % par rapport au moteur dans lequel la puissance est mise hors tension uniquement dans certains des cylindres de travail.
