摘要： 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.

摘要： An engine includes an exhaust conduit (150) having an exhaust port on an end of the exhaust conduit. The exhaust conduit has an angled inside surface that has a cross section that widens toward the exhaust port. The engine further includes a muffler (128) having a housing (136) with an intake pipe (168). The intake pipe is inserted through the exhaust port such that the intake pipe is wedged into the angled inside surface of the exhaust conduit.

摘要： A single-cylinder, four-stroke cycle, internal combustion engine arranged in an overhead valve configuration includes a first valve train and a second valve train. The first valve train includes a first cam on a camshaft, a first pushrod driven by the first cam, a first rocker arm attached to the first pushrod, and an exhaust valve driven by the first rocker arm. The second valve train includes a second cam on the camshaft, a second pushrod driven by the second cam, a second rocker arm attached to the second pushrod, and an intake valve driven by the second rocker arm. The first rocker arm is longer than the second rocker arm.
