INTAKE CONTROLLER OF INTERNAL COMBUSTION ENGINE

Japanese Patent JP2009007989

A

To improve fuel consumption, output, and emission by suppressing the occurrence of pumping loss (intake resistance).

The tumble flow in the combustion chamber of an engine is reinforced by merely opening and closing an intake valve 4 so that the valve center axis of the intake valve 4 when the intake valve 4 is opened is different from the valve center axis of the intake valve 4 when the intake valve 4 is closed without forming a projection and an intake adjustment part (block wall part) inside the intake port 2 of the engine. The occurrence of the pumping loss (intake resistance), therefore, is suppressed when the amount of the intake air is large (namely, when a throttle valve is fully opened), and the tumble flow in the combustion chamber of the engine is reinforced. Since the combustion efficiency in the combustion chamber when the throttle valve is fully opened is improved, the fuel consumption, output, and emission are improved.
