Cooling system for air-cooled engine

摘要

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.

主权项

1. An air-cooled internal combustion engine, comprising:
a crankshaft; a first cylinder; a blower assembly including a blower housing and a fan; and a static cover including a main body aligned with the crankshaft, a first arm extending from the main body and aligned with the first cylinder, and a plurality of air intake openings, wherein 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 first arm, and wherein the static cover is configured to prevent user access to a moving component of the engine; wherein the fan is configured to move air into the blower housing through the air intake openings; and a second cylinder, wherein the static cover includes a second arm extending from the main body and aligned with the second cylinder and wherein a third subset of the plurality of air intake openings is formed through the second arm, wherein the fan is configured to move air into the blower housing through the air intake openings when rotating in a first direction in a cooling mode and to move air out of the blower housing through the air intake openings when rotating in an opposite second direction in a debris-removal mode.
