ABSTRACT:
In an engine induction system, a drive frequency f1 of an ISC valve 13 for duty control and a characteristic frequency f2 of an intake passage between an air cleaner 8 and a throttle valve 11 are set so as to obtain a relationship: (3/4)f1.ltoreq.f2.ltoreq.(5/4)f1. In this set system, a resonance chamber 17 is connected to the intake passage between the air cleaner 8 and the throttle valve 11 to thereby deaden the vibration caused by the driving of the ISC valve 13. Accordingly, the engine induction system is allowed to prevent the amplification of the vibration accompanying the actuation of the ISC valve so as to prevent the deterioration of the detection accuracy of an airflow meter while being allowed to meet requirements such as an improvement in the responsiveness when the ISC valve disposed in an ISC pipe is duty controlled.
