Title:
ENGINE CONTROL DEVICE AND ENGINE CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2023/242979
Kind Code:
A1
Abstract:
This engine control device comprises a control unit that receives a detection signal from a cam angle sensor that detects rotation of an intake value or an exhaust valve. When the engine is stopped or restarted, the control unit causes the phase of the intake valve or the exhaust valve to be changed by a valve-timing-variable mechanism. For a prescribed time following the detection timing of detection by the cam angle sensor, the control unit reduces the amount by which the phase is changed by the valve-timing-variable mechanism so as to be less than the amount of change that preceded the detection timing.
