Abstract
An intake control device for a vehicle engine includes: a throttle body; a main throttle valve configured to be opened or closed in response to an operation applied to a throttle grip, the main throttle valve being rotatably supported by the throttle body; a sub-throttle valve configured to be opened or closed under control of an actuator, the sub-throttle valve being rotatably supported by the throttle body; an intake air path formed in the throttle body and provided with the main throttle valve and the sub-throttle valve so as to open or close the intake air path; and a bypass air path that is different from the intake air path and provided with an idle speed control (ISC) valve that is controlled so as to open or close the bypass air path in conjunction with the sub-throttle valve.

An intake control device for a vehicle engine, comprising:
- a throttle body;
- a main throttle valve configured to be opened or closed in response to an operation applied to a throttle grip, the main throttle valve being rotatably supported by the throttle body;
- a sub-throttle valve configured to be opened or closed under control of an actuator, the sub-throttle valve being rotatably supported by the throttle body;
- an intake air path formed in the throttle body and provided with the main throttle valve and the sub-throttle valve so as to open or close the intake air path;
- and
- a bypass air path that is different from the intake air path and provided with an idle speed control (ISC) valve that is controlled so as to open or close the bypass air path in conjunction with the sub-throttle valve.
