    • Internal combustion engine, with cylinders' body (1) being an individual component, separate from the crankshaft base (29), thus enabling it to move and the cylinder head (3) of which features a common induction-exhaust valve (4) per cylinder, driven by a cam (5), and two secondary auxiliary valves (7), (8), or alternatively (19), (20) per cylinder, for the assistance the main valve during the induction and exhaust strokes. Each engine cylinder (1) has a port (26), at a specified height, where a displacement variation valve (25), and alternatively (27), is mounted, through which a controllable amount of air escapes, during compression as well as when a displacement variation is desired. With the common induction-exhaust valve (4), the compression ratio can be increased to high levels, since this valve is sufficiently cooled, thus preventing the occurrence of self-ignition. With the displacement variation valve, the engine's displacement and, consequently, its fuel consumption and emission level can be reduced, when desired. With the upward and downward movement of the cylinders' body, the combustion area is increased and decreased respectively, and therefore, the combustion ratio is altered, regardless of the displacement.
    • 内燃机,其具有与曲轴基座(29)分离的单独部件的缸体(1),从而使其能够移动,并且其缸盖(3)具有公共的排气阀(4) 由凸轮(5)驱动的气缸,以及每个气缸的两个辅助辅助阀(7),(8)或备选地(19),(20),用于在感应和排气冲程期间辅助主阀。 每个发动机气缸(1)具有在特定高度处安装有位移变化阀(25)和可选择地(27)的端口(26),通过该端口可控量的空气在压缩期间逸出,以及 当需要位移变化时。 利用普通的排气阀(4),可以将压缩比提高到高水平,因为该阀被充分冷却,从而防止自燃。 利用位移变化阀,当需要时,可以减小发动机的排量,并因此降低其燃料消耗和排放水平。 随着气缸体的向上和向下运动,燃烧面积分别增加和减小,因此燃烧比不管位移如何变化。
