ABSTRACT:
An intake system for an automobile engine with a manual transmission or an automatic transmission has a throttle valve disposed in an intake passage for distributing air into cylinders of the engine. A supplementary air distributor provided in association with the intake passage supplementarily distributes air into the intake passage between the throttle valve and engine. The supplementary air distributor is controlled by a controller to distribute different amount of supplementary air according to engine operating conditions. The controller is correctively controlled to vary the amount of supplementary air, by the supplementary air distributor according to atmospheric pressure for every distribution, so as to distribute a larger amount of supplementary air do an automobile engine with an automatic transmission than do an automobile engine with a manual transmission at the same atmospheric pressure.
