Abstract
An integrated intake manifold and air cleaner system is provided by a molded plastic induction module including molded lower and upper manifold pieces welded together. A series of upright walls on the upper manifold and a cover piece form a box-like enclosure in which an air cleaner element is disposed mounted to a throttle body on the upper manifold piece. A fuel rail and injector are also disposed within the enclosed space. Other components such as the ECU can optionally be mounted within the enclosed space. Resonator and expansion chambers are also defined within the enclosed space.
Claims11
An induction module including an integrated intake manifold and air cleaner system for an internal combustion engine, said induction module comprising:
- a molded plastic intake manifold having upright walls;
- a plurality of said walls integrally molded with an upper portion of said intake manifold and upwardly extending about the perimeter of said intake manifold;
- a molded plastic cover piece detachably fit to upper edges of said upright walls to define an enclosed space within said walls wherein said cover piece includes a baffle portion extending downward from the inside of said cover piece and fit to an upper side of said intake manifold to subdivide said enclosed space into two compartments;
- said intake manifold including a plenum and a series of runners;
- a throttle body mounted to said plenum and disposed within said enclosed space;
- an air cleaner element mounted to said throttle body and also disposed within said enclosed space, said air cleaner element in one of said compartments.
