  • Patent number: 9228545
    Abstract: A pre-cleaner for use with an internal combustion engine includes a base having a substantially planar interior surface, a scavenge port, and a plurality of separators extending substantially perpendicularly from the interior surface. The pre-cleaner also includes a baffle removably connected to the base, the baffle having a plurality of separator features configured to mate with the plurality of separators. The pre-cleaner further includes a deck disposed between the interior surface and the baffle. The deck is positioned at an acute angle relative to the interior surface such that a first portion of the deck is disposed closer to the interior surface than a second portion of the deck.
