Abstract:

A blower housing for use with an engine. The blower housing is adapted to receive a stream of intake air, and the engine includes at least one cylinder. The blower housing includes an intake opening, an air filter housed within a filter compartment, and an air flow duct adjacent to the filter compartment. The air flow duct is configured to direct air to the at least one cylinder. The air flow duct includes a first surface and a second surface, the first surface being angled with respect to the second surface to deflect the air passing through the duct away from the first surface toward the second surface. The first surface separates the air into a first portion and a second portion having deflected particulate matter therein. The duct also has an aperture that allows air to flow from the duct to the air filter, and an exhaust window.
