Abstract
Abstract An intake manifold assembly of a variable intake passage length includes a branch passage body 27 for introducing air from a main throttle valve (34) into intake ports (25) of an engine. The branch passage body has an intake chamber (33) communicating with the main throttle valve, a plurality of shorter passages (43) extending upwardly from the intake chamber and each having an auxiliary throttle valve (45) for selectively opening and closing the shorter passage, a plurality of longer passages (42) extending from the intake chamber around a lower side of the intake chamber, the shorter and longer passages having downstream ends joined to each other at respective junctions, and connected to the intake ports. The branch passage assembly comprises an upper member (27a), a lower member (27b), and an intermediate member (27c) sandwiched between the upper and lower members, the intake chamber being defined in the lower member, the shorter passages being defined in the upper and intermediate member, the longer passages being defined in the upper, intermediate, and lower member, a connection to the intake ports being defined in the upper member, the auxiliary throttle valves being angularly movably disposed respectively in the shorter passages in the intermediate member.
