Abstract
An air intake device for a marine propulsion engine that effectively separates water from the intake air and precludes that water from being swept back into the induction system for the engine. A plenum chamber is formed as a separate part of the air intake device and is connected to the carburetor through a transition portion that extends across the upper end of the plenum chamber. The plenum chamber is displaced forwardly of the carburetor so as to not interfere with it or restrict its size.
Claims14
An air induction system for the air intake of an internal combustion engine for powering a watercraft having a hull in which said engine is positioned, said air intake extending in a generally vertical direction and having an upper opening, said induction system comprising an air intake device having a plenum chamber formed of substantial volume and displaced from said air intake and depending a substantial distance below said upper opening and within said hull, an atmospheric air inlet entering said plenum chamber at the top thereof and directed to cause the atmospheric air to flow toward the lower end of said plenum chamber, and a discharge communicating said plenum chamber with said upper opening.
