Title:
VARIABLE COMPRESSION RATIO INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2014/129088
Kind Code:
A1
Abstract:
The present invention is equipped with: a variable compression ratio mechanism (10) that changes the engine compression ratio in response to the rotational position of a first control shaft (14); and an actuator that changes and maintains 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). One end of the lever (24) and the tip of a first arm part (25) extending radially outward from the center of the first control shaft (14) are rotatably linked by a first linking pin (26). At least when the setting is at the highest compression ratio the first linking pin (26) is submerged below the surface (α1) of the oil in an oil pan (6).
