Abstract

See full text

An engine assembly includes a crankcase, shaft, blower housing, and cooling fan. The shaft is rotatably coupled to the crankcase and defines a rotational axis. The blower housing includes an internal space. The cooling fan is disposed within the internal space, includes a plate defining an upper surface, and is positioned to rotate with the shaft about the rotational axis. The cooling fan includes a band having an inner band radius and an outer band radius. The cooling fan includes a plurality of reversed fins extending between the band and the upper surface and between a root adjacent to the rotational axis and a tip adjacent to the outer band radius, each fin offset at an angle measured in a counterclockwise direction from a plane passing through the rotational axis and the tip to a plane passing through the root and the tip when viewed from above the cooling fan.
