    摘要： A valve control device includes a valve unit disposed in a cooling water circuit, and a control part which controls operation of the valve unit. The control part has a rotation angle instruction part, a duty ratio calculator and a determiner. The rotation angle instruction part calculates an instruction value of a rotation angle in response to an operational status of an internal-combustion engine. The duty ratio calculator calculates a duty ratio representing a ratio of ON period to OFF period regarding a voltage applied to an electric motor based on a difference between a detection value of the rotation angle detected by a detector and the instruction value of the rotation angle, and regulates the duty ratio to be lower than or equal to a predetermined upper limit. The determiner determines whether the duty ratio continues to be the upper limit during a predetermined period.

    摘要： A variable intake air device forms a long port and a short port in each of branches of an intake air manifold. The variable intake air device switches between the long port and the short port. A gas introduction device draws gas into each of the branches. When the engine is in a high load region, the variable intake air device uses the long port, when an engine rotation speed is less than a predetermined rotation speed, and uses the short port, when the engine rotation speed is greater than or equal to the predetermined rotation speed. When the engine is in a low load region, the variable intake air device switches between the long port and the short port according to the engine rotation speed.

    摘要： A valve device includes a valve housing, a valve member, a limiter, a contact portion and a shaft. The valve housing has an inside space and a plurality of housing-side openings. The housing-side openings communicate between the inside space and an outside of the valve housing. The valve member is rotatably received in the valve housing and has: a plurality of valve-member-side openings, each of which is configured to communicate with a corresponding one of the housing-side openings; and a communication passage, through which the valve-member-side openings is communicated with each other. The limiter is configured to limit rotation of the valve member. The contact portion is provided in a space of the valve member and is configured to contact the limiter. The shaft rotatably supports the valve member.

    摘要： A housing has a housing main body and an outlet port. The housing main body includes a cylindrical housing inner wall that defines an internal space therein. The outlet port fluidly connects the internal space and an outside of the housing main body to each other. The valve has a valve body rotatable about an rotation axis along a rotation axis of the cylindrical housing inner wall. The valve is configured to selectively open and close the outlet port depending on a rotation position of the valve. The housing inner wall is formed such that a distance between the housing inner wall and the axis of the housing inner wall varies in a circumferential direction.

    摘要： A resonator has a volume chamber, which is communicated with a surge tank through a communication passage. A primary intake passage communicates between a cylinder of an internal combustion engine and the surge tank. A secondary intake passage communicates between the surge tank and one of the cylinder and the primary intake passage. A passage length of the secondary intake passage is shorter than a passage length of the primary intake passage. A variable intake valve is fixed to a shaft. The variable intake valve opens and closes the secondary intake passage. A resonator valve is fixed to the shaft. The resonator valve opens and closes the communication passage. A drive device rotates the shaft to drive the variable intake valve and the resonator valve.
