Intake Manifold
DESCRIPTIONFig. 6
This intake manifold system (Fig. 6) is composed of a upper intake manifold plenum and a lower manifold. This aluminum alloy manifold has long runners to improve inertia. The upper intake plenum chamber (surge tank) absorbs air pulsations created during the suction phase of each cylinder. The lower intake manifold is machined for six injectors and fuel rail mounting.
OPERATION
The intake manifold meters and delivers air to the combustion chambers. This air allows the fuel delivered by the fuel injectors to ignite, thus producing power.
