Title:
可変圧縮比機構付き内燃機関の制御装置
Document Type and Number:
Japanese Patent JP4207729
Kind Code:
B2
Abstract:
A control apparatus for an internal combustion engine (1) includes a variable compression ratio mechanism (100) capable of varying a compression ratio of the engine, a knock sensor (27) for detecting a knock occurrence sate, and a controller (20) for controlling the compression ratio and an ignition timing of the engine, the controller including a compression ratio setting section that sets a compression ratio to be attained by the variable compression ratio mechanism (100) in accordance with an operating condition of the engine (1), and an ignition timing learning correcting section that determines a learning correction value of an ignition timing in accordance with the knock occurrence sate, wherein the controller (20) further includes a compression ratio correcting section that corrects the compression ratio set by the compression ratio setting section in accordance with the learning correction value of the ignition timing. A control method is also provided.
