  • Patent number: 8720392
    Abstract: A blower system for an engine includes a base of a blower scroll coupled to an engine crankcase. The base has a bottom wall with an opening sized to accommodate an end of a crankshaft. The base also has a sidewall extending away from the crankcase. The blower system further includes a blower housing fastened to the base, without the use of threaded fasteners. Together the blower housing and the base form a chamber having an inlet and an outlet. Also, the blower system includes a fan within the chamber. The fan is driven by the crankshaft and is designed to direct a flow of air through the outlet of the chamber.
