IDLE INTAKE AIR ADJUSTMENT DEVICE

WIPO Patent Application WO/2013/105426

A1

Provided is an idle intake air adjustment device with which gear shift shock during downshifting of the transmission can be effectively alleviated. This idle intake air adjustment device (100) is equipped with an idle adjustment device (110) and an ECU (300). A bypass passage (112) is provided within the body (111) of the idle adjustment device (110), and an idle adjustment valve (120) is provided within the bypass passage (112). The cylindrically formed valve main body (121) of the idle adjustment valve (120) is equipped with an inflow-side aperture part (122), an outflow-side aperture part (123), and a second aperture part (124). The inflow-side aperture part (122) opens in the axial direction of the valve main body (121), thereby introducing intake gas. The outflow-side aperture part (123) is formed in the outer circumferential part of the valve main body (121), and supplies intake gas during idling. The second aperture part (124) is formed in the outer circumferential part of the valve main body (121), has a larger aperture area than the outflow-side aperture part (123), and supplies intake gas for blipping.
