摘要： 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.

摘要： The system consists of a pump (1) which brings the hydraulic liquid under pressure through a suitable line to the common supply line (7), wherefrom, controlled by a computer. It is passed though one way electromagnetic valves (9) and flow adjusters (11), to a cylinder (13), the piston (14) of which, pressed, pushes the stem of the valve (16) of the engine and opens it. The closure of the valve (16) is effected by its return spring, once the one-way electromagnetic valve (10) is activated, in which case the liquid is transported via a tube (18) to a common return lien (20). From there it is directed to the inlet of the pump (1), thus creating a closed circuit. In this manner, by controlling the supply of liquid to each cylinder (13) and the duration of its pressure onto the piston (14), one can adjust the size and the duration of the opening of each valve (16), achieving infinite timing variations.
摘要翻译：该系统由泵（1）组成，该泵将压力下的液压液体通过合适的管路输送到公共供应管线（7），由计算机控制。它通过单向电磁阀（9）和流量调节器（11）通过气缸（13），其中的活塞（14）被按压，推动发动机的阀（16）的阀杆并将其打开。一旦单向电磁阀（10）被激活，阀（16）的关闭就通过其复位弹簧来实现，在这种情况下，液体通过管（18）输送到公共回流留置口（20）。从那里它被引导到泵（1）的入口，从而产生闭合回路。以这种方式，通过控制向每个气缸（13）的液体供应及其对活塞（14）的压力的持续时间，可以调节每个阀（16）的开度的大小和持续时间，实现无限时间变化。
