Air intake system for a marine engine

摘要

An air intake box for a four-stroke marine engine. The air box is generally U-shaped in configuration, including a lower section that is connected to the carburetor throat. The lower section extends forwardly from the carburetor and merges into an upper section via a reverse bend. The upper section extends rearwardly above the carburetor and terminates in a distal inlet end that is located at the rear of the engine. The air box reduces air intake noise, and results in cooler air being supplied to the engine, which enhances combustion.
