Abstract
An idle-adjusting device for an engine having an air intake passage and a throttle valve disposed in the air intake passage, includes an auxiliary passage communicating with the air intake passage in such a manner as to bypass the throttle valve. A first variable restriction is provided in the auxiliary passage to adjustably reduce the local cross-sectional area of the auxiliary passage. A second variable restriction is provided in the auxiliary passage downstream of the first restriction to adjustably reduce the local cross-sectional area of the auxiliary passage. The first and second restrictions adjustably determine the effective cross-sectional area of the auxiliary passage.
