    Study Notes

    Air Induction System

    • Ram air enters the engine through an opening in the forward part of the lower engine cowling nose cap.
    • The air is filtered through a filter located at the opening in the nose cap.
    • The filtered air is directed to the inlet of the carburetor, mounted on the lower side of the engine.
    • In the carburetor, fuel is mixed with the air to create a fuel-air mixture.
    • The fuel-air mixture is distributed to each cylinder by separate intake pipes attached to the intake manifold.
    • The intake pipes are attached to the intake manifold with hose and clamps, and to the cylinder with a two-bolt flange sealed with a gasket.

    Anti-Icing System

    • The induction airbox contains a valve operated by the carburetor heat control in the cabin.
    • The valve permits air from an exhaust-heated source to be selected in case of carburetor icing or filter icing.
