  "textContent": "An internal combustion engine includes an intake port (5) leading to an engine cylinder (2). The intake port is divided into first and second passage section (5A,5B) by a partition (11) extending in the intake port in a longitudinal direction of the intake port. A gas motion control valve (31) is arranged to open and close an upstream end of the second passage section. A connection passage (12,12') connects an upstream end portion of the second passage section (5B) to the first passage section (5A). A bulge (51,52) is formed in a first part of a circumferential region surrounding the downstream port end (43) so as to prevent air from being drawn from the cylinder into the second passage section (5B).",
