摘要： A variable compression ratio internal combustion engine includes a control shaft (13) rotatably supported by an engine body, a variable compression ratio mechanism (10) for changing an engine compression ratio in accordance with a rotational position of the control shaft (13), an actuator (21) that rotatively drives the control shaft (13), and a speed reducing mechanism (22) for reducing a rotational power of the actuator (21) and for transmitting the speed-reduced power to the control shaft (13). The speed reducing mechanism (22) has a rotation shaft (24) rotatably supported in a housing (26) fixed to the engine body and a lever (25) that connects the rotation shaft (24) and the control shaft (13). Located in the engine body is a first regulation part (42) for mechanically regulating the control shaft (13) to a position of maximum rotation on one side of a low compression ratio side and a high compression ratio side. Also located in the housing (26) is a second regulation part (41) for mechanically regulating the rotation shaft (24) to a position of maximum rotation on the other side of the low compression ratio side and the high compression ratio side.

摘要： There are provided a variable compression-ratio mechanism (20) capable of varying an engine compression ratio in accordance with a rotational position of a control shaft (24); a speed reducer (44) configured to reduce in speed a rotational power of an actuator and transmit the speed-reduced rotational power to the control shaft (24); and a speed-reducer accommodating case (43) accommodating the speed reducer (44). An input shaft of the speed reducer (44) which is connected to the actuator has a shaft center line extending along a horizontal direction, and at least a part of the input shaft is kept under a lubricating oil retained in the speed-reducer accommodating case (43). The input shaft of the speed reducer (44) is swung by a predetermined swing angle to avoid inadequate lubrication of the input shaft of the speed reducer (44), during an operating state where the engine compression ratio is maintained constant.

摘要： The control shaft (20) of a variable compression ratio mechanism is coordinated with the auxiliary shaft (25) of an actuator device (1) through an intermediate link (31). The housing (5) of the actuator device (1) has on the lower surface thereof an oil filter mounting seat section (36), and a stopper section (37) is formed integrally with the oil filter mounting seat section (36). A second arm (28) of the auxiliary shaft (25) comes in contact with the stopper section (37) to define the limit of the compression ratio on the low compression ratio side. The stopper section (37) has high rigidity because the oil filter mounting seat section (36) having high rigidity and the stopper section (37) are integrated together.

摘要： A stopper (32) includes one end-side side wall (33) confronting one end surface of a control shaft side link pin irrespective of a rotation positon of the control shaft; the other end-side side wall (34) confronting the other end surface of the control shaft side link pin irrespective of the rotation position of the control shaft; one end side flange (36) fixed to an upper oil pan (23); and the other end side flange (37) fixed to the upper oil pan (23). With this, the end surface of the control shaft side link pin is partially overlapped with the one end-side side wall (33) and the other end-side side wall (34) of the stopper (32) when viewed in an axial direction of the control shaft side link pin, irrespective of the rotation position of the control shaft. Accordingly, it is possible to surely prevent the control shaft side link pin from falling off in the axial direction of the control shaft side link pin, irrespective of the rotation position of the control shaft.
