Intake system of internal combustion engine |
摘要 |
An internal combustion engine includes an intake port leading to an engine cylinder. The intake port is divided into first and second passage section by a partition extending in the intake port in a longitudinal direction of the intake port. A gas motion control valve is arranged to open and close an upstream end of the second passage section. A connection passage connects an upstream end portion of the second passage section to the first passage section. A bulge is formed in a first part of a circumferential region surrounding the downstream port end so as to prevent air from being drawn from the cylinder into the second passage section.
