Abstract

La présente invention concerne un procédé de contrôle du déroulement d'un cycle de fonctionnement d'un moteur à combustion interne comprenant au moins un cylindre (14) à l'intérieur duquel coulisse un piston (10) entre des positions extrêmes hautes (PMH) et basses (PMB), un embiellage (18) reliant le piston à deux vilebrequins (16a, 16b) de sens de rotation (R), un système de distribution (36) pour au moins une soupape d'admission (38) et au moins une soupape d'échappement (40), ce cycle comprenant une phase de détente avec une course (D1) du piston plus grande que celle (C1) de la phase de compression selon un intervalle d'angle de vilebrequin de détente (VD1) plus grand que celui de la phase de compression. Selon l'invention, le procédé consiste à réduire l'intervalle d'angle de vilebrequin de détente (VD1) et à obtenir une augmentation de la vitesse de détente dudit piston après la position extrême haute de la course de détente.The present invention relates to a method for controlling the course of an operating cycle of an internal combustion engine comprising at least one cylinder (14) inside which a piston (10) slides between extreme high positions (TDC). and low (PMB), a connecting rod (18) connecting the piston to two crankshafts (16a, 16b) of direction of rotation (R), a distribution system (36) for at least one inlet valve (38) and to the minus one exhaust valve (40), this cycle comprising an expansion phase with a stroke (D1) of the piston greater than that (C1) of the compression phase according to an expansion crankshaft angle interval (VD1) larger than that of the compression phase. According to the invention, the method consists in reducing the interval of relaxation crankshaft angle (VD1) and in obtaining an increase in the expansion speed of said piston after the extreme high position of the expansion stroke.
