Title:
VARIABLE COMPRESSION RATIO INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2016/035127
Kind Code:
A1
Abstract:
A link mechanism (22) linking a variable compression ratio mechanism (10) that changes an engine compression ratio according to a rotation position of a first control shaft (13) and an actuator (20) includes a lever (25) linking the first control shaft (13) and a second control shaft (24), wherein a combustion load that acts on the first control shaft (13) is transmitted to the second control shaft (24) through the lever (25). A first link pin (28) links a distal end of a first arm portion (27) extending from the first control shaft (13) towards the outside in the radial direction and one end of the lever (25) in a relatively rotatable manner, and a second link pin (30) links a distal end of a second arm portion (29) extending from the second control shaft (24) towards the outside in the radial direction and the other end of the lever (25) in a relatively rotatable manner. A diameter (D1) of the first link pin (28) is set larger than a diameter (D2) of the second link pin (30).
