摘要： A variable compression ratio internal combustion engine basically has a main engine body and a variable compression ratio mechanism. A housing is attached to an outside wall of the main engine body to support an actuator. The variable compression ratio mechanism varies an engine compression ratio according to a rotational position of a first control shaft by the actuator. A second control shaft links the actuator to the first control shaft. A bearing includes a pair of split bearing bodies that rotatably holds and supports the second control shaft on the housing. The split bearing body that is farther from the main engine body has higher in rigidity than the housing. The bearing is fixed to the side wall of the main engine body by fixing bolts that pass through both of the split bearing bodies and thread into the side wall of the main engine body.

摘要： A variable compression ratio mechanism for an internal combustion engine includes a gear reducer that varies an engine compression ratio. The gear reducer includes an input-side member connected to a rotation shaft of the actuator; an output-side member that transmits a reduced rotation of the actuator to the control shaft; a fixed member fixed to a housing of the actuator; and an intermediate member that transmits torque from the input-side member to the output-side member and the fixed member, and has a first gear portion engaged with the fixed member and a second gear portion engaged with the output-side member. A ratio of a number of teeth of the fixed gear portion to a number of teeth of the first gear portion is higher than a ratio of a number of teeth of the output-side gear portion to a number of teeth of the second gear portion.

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： It is an object to increase the reliability and durability by minimizing mixing/entry of foreign matter (contaminants) into a speed reducer. The speed reducer is provided for reducing rotation of an actuator of a variable compression ratio mechanism and for transmitting the reduced rotation to a control shaft of the variable compression ratio mechanism. The actuator and the speed reducer are attached to a sidewall of an engine main body with a housing therebetween. An oil filter, which removes contaminants from within lubricating oil, is attached to the housing with an oil-passage-forming body therebetween. A portion of the lubricating oil supplied from the oil filter immediately after having been filter-purified is supplied via a bypass oil passage, formed in the oil-passage-forming body and the housing, into a speed-reducer accommodation chamber of the housing.
