Title:
INTERNAL COMBUSTION ENGINE CONTROL DEVICE AND INTAKE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/163892
Kind Code:
A1
Abstract:
A combustion chamber (12) of an internal combustion engine (10) has a circular inner peripheral surface, and communicates with an intake port (20) via two intake openings (21) and with an exhaust port (14) via an exhaust opening (13). The internal combustion engine (10) is provided with: an ignition plug (16) disposed at the center of a ceiling portion covering the combustion chamber (12), and an airflow adjusting portion (50) for adjusting an airflow generated in the combustion chamber (12). This control device (60) for the internal combustion engine (10) is provided with: a drift current determination unit which determines that a drift current be generated by strengthening the airflow at the position of the ignition plug (16) compared to the airflow at other positions; and a control unit which causes the airflow adjusting portion (50) to generate a drift current if it is determined that a drift current be performed.
