  • Patent number: 10443538
    Abstract: An air-cooled internal combustion engine including a crankshaft, a cylinder, a blower assembly including a blower housing and a fan, and a static cover. The static cover includes a main body that is aligned with the crankshaft, an arm that extends from the main body and is aligned with the cylinder, and a plurality of air intake openings. A first subset of the air intake openings is formed through the main body and a second subset of the air intake openings is formed through the arm, and the static cover is configured to prevent user access to a moving component of the engine. The fan is configured to move air into the blower housing through the air intake openings.

  • Patent number: 9500117
    Abstract: An air-cooled internal combustion engine includes an engine block, a blower assembly including a blower housing and a fan, and a static cover. The static cover includes multiple air intake openings and is configured to prevent user access to a moving component of the engine. The blower housing is configured to at least partially direct air to the engine block. The fan is configured to move air into the blower assembly through the air intake openings when rotating in a first direction in a cooling mode and to move air out of the blower assembly through the air intake openings when rotating in an opposite second direction in a debris-removal mode.
