| 摘要 |
<p>The invention relates to a process and a device for setting the compression ratio of an internal combustion engine by changing the relative distance between the rotational axis (7a) of the engine crankshaft (7) and the surface of the engine cylinder head (2) which delimits the end of each cylinder (4) in the engine. The process according to the invention is characterized in that the relative displacement between the rotational axis (7a) of the crankshaft (7) and the cylinder head (2) is carried out in such a manner that the rotational axis of the crankshaft is displaced both parallel to a plane containing the longitudinal axis of each of the engine cylinders (4), and perpendicular to said plane. The device according to the invention is characterized in that the crankshaft (7) is mounted for rotation in excentrically placed bearing openings (16) in circular adjustment discs (13), which are rotatably mounted in the bearing openings (19) in the engine block (1). Furthermore, a rotating device (31, 34, 35) is coupled to the adjustment discs (13) for simultaneous rotation thereof relative to the engine block (1).</p> |
