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.

摘要： Provided is an internal combustion engine including two intake valves for each cylinder, the internal combustion engine including: a fixed cam for driving one of the two intake valves with a lift characteristic having a valve opening timing close to a top dead center; a variable valve actuation mechanism capable of changing, in accordance with an engine running condition, lift characteristics between a low-lift characteristic having an event angle and a lift amount each being smaller than an event angle and a lift amount of the fixed cam, and a high-lift characteristic having the event angle and the lift amount each being larger than the event angle and the lift amount of the fixed cam; and a variable cam for driving another of the two intake valves, the variable cam including the variable valve actuation mechanism, in which the variable valve actuation mechanism is configured to set the lift characteristic of the variable cam so as to obtain a valve opening timing on a retard side relative to the valve opening timing of the fixed cam in a case of the low-lift characteristic.
