Patent ID: 6918372

Claim:
An internal combustion engine, comprising: a cylinder head defining an intake port leading to a cylinder of the engine; an intake valve located at a downstream end of the intake port; a flow regulating section to regulate an intake air flow in the intake port, the flow regulating section including; a partition extending in the intake port in a longitudinal direction of the intake port from an upstream end to a downstream end which is located in the cylinder head, and dividing the intake port into first and second passage sections; a gas motion control valve located by the upstream end of the partition, to open and close the second passage section; and a connection passage to allow recirculating flow of intake air in the second passage section from the second passage section to the first passage section when the second passage section is closed by the gas motion control valve; and a fuel injector directed to inject fuel toward a valve opening of the intake valve through a space on the downstream side of the downstream end of the partition.
