CA 2476240
A variable compression ratio engine includes a connecting rod connected to a piston, a subsidiary arm connected to a crankshaft with one end pivotally connected to an end of the connecting rod, an eccentric shaft provided at an eccentric position of a rotary shaft rotatably supported at an engine body, and a control rod with one end connected to the subsidiary arm at a position deviated from the connected portion of the connecting rod and the other end pivotally connected to the eccentric shaft . In the variable compression ratio engine, a one-way clutch is interposed between the rotary shaft and the engine body, a restricted member is interlocked with and connected to an eccentric position of the rotary shaft to reciprocally operate corresponding to rotation of the rotary shaft, and a restricting device abuts to and engages with the restricted member immediately after the restricted member passes a reciprocation end, thereby selectively restricting a rotational operation of the rotary shaft in either of two rotation phases different from each other. Thus, the rotary shaft is rotated by utilizing the combustion and inertia of the engine, and occurrence of impact at the time of restricting the rotational operation of the rotary shaft can be suppressed.
