The arrangements of the passages is such that the change in length is achieved quite simply by positioning a throttle valve at the upstream end of the short induction passage and having both passages communicate with an air inlet device. Several embodiments of throttle valve arrangements are also disclosed wherein a single throttle valve can control the flow through two adjacent induction passages.
