Title:
CONTROL METHOD FOR INTERNAL COMBUSTION ENGINE AND CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2017/154269
Kind Code:
A8
Abstract:
In the present invention, because a variable compression ratio mechanism (5) is a multi-link piston crank mechanism configured with multiple links for linking a piston 4 with a crankshaft (6), a combustion load acts so as to push the piston (4) downward. Therefore, response speed is faster when changing the compression ratio to a low compression ratio side than when changing the compression ratio to a high compression ratio side. Thus, response speed of the change to the low compression ratio side is set faster than response speed of the change to the high compression ratio side. Consequently, the change to the low compression ratio side can be achieved at a faster response speed than to the high compression ratio side without conforming to the response speed of the high compression ratio side such that deterioration of responsiveness can be suppressed.
