Title:
INTERNAL COMBUSTION ENGINE CONTROL DEVICE AND CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2019/198320
Kind Code:
A1
Abstract:
Provided are a novel internal combustion engine control device and a control method therefor that, in an internal combustion engine comprising a variable phase valve timing mechanism, can accurately produce a target torque of the internal combustion engine whether in high-altitude conditions or low-altitude conditions. A control device that controls an internal combustion engine, said internal combustion engine comprising a combustion cylinder, a throttle valve that is positioned in an intake passage of the combustion cylinder, an intake valve that is positioned in an intake opening of the combustion cylinder, an exhaust valve that is positioned in an exhaust opening of the combustion cylinder, and a variable phase valve timing mechanism that varies the opening timings of the intake valve and the exhaust valve, wherein the internal combustion engine control device is characterized by comprising a control unit that changes the amount of openness of the throttle valve on the basis of a change in atmospheric absolute pressure, and reduces the amount of openness of the throttle valve in accordance with a longer overlap period of the opening of the intake valve and the exhaust valve.
