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： An internal combustion engine (1) that has a variable-compression-ratio mechanism (2) has variable valve mechanisms (7, 8) for an intake valve (4) and an exhaust valve (5), respectively. If a malfunction in the variable-compression-ratio mechanism (2), which controls a mechanical compression ratio via an electric motor (31), is detected from the amplitude of variations in an actual compression ratio, then if the fuel supply to the engine is cut, a throttle valve (14) is opened wider than would be the case if the variable-compression-ratio mechanism (2) were not malfunctioning, thereby reducing in-cylinder negative pressure during the intake stroke. Also, the timing with which the intake valve is closed is advanced and the timing with which the exhaust valve is opened is retarded, increasing the in-cylinder positive pressure during the compression and power strokes. This prevents the variable-compression-ratio mechanism (2) from increasing the compression ratio when control is lost.

摘要： The present invention is equipped with a variable compression ratio mechanism (10) that changes an engine compression ratio depending on the rotational position of a first control shaft (14), and an actuator that changes and holds the rotational position of the first control shaft (14). A linking mechanism linking the actuator and the first control shaft (14) has a lever (24) linked to the first control shaft (14). The tip of an arm part (25) extending radially outward from the center of the first control shaft (14) and one end of the lever (24) are rotatably linked by a first connecting pin (26). At least when having been set to the highest compression ratio, the first connecting pin (26) is submerged below an oil level (±1) of the oil pan (5).
