Patent number: 8746207Abstract: An internal combustion engine includes a muffler configured to reduce exhaust gas noise. The muffler has a housing defining an interior and an exterior. A choke valve is configured to control a flow of air in a carburetor and a thermally responsive element is coupled with the choke valve and configured to move the choke valve in response to a temperature change in the thermally responsive element. A thermally conductive member has a first portion positioned in the interior of the muffler and extending through the muffler housing to the exterior of the muffler, and a second portion positioned exteriorly of the muffler and coupled to the thermally responsive element. The thermally conductive member is configured to conduct heat from exhaust gases within the muffler to the thermally responsive element.Type: GrantFiled: July 3, 2013Date of Patent: June 10, 2014Assignee: Briggs and Stratton CorporationInventors: Christopher J. Drew, David W. Branski, Chad J. Gartzke, William H. Mayer, Benjamin R. Miller, Dawn N. Traynor, Gene Zimmerman, Jean-Paul Benjamins

Patent number: 8720392Abstract: 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.Type: GrantFiled: February 21, 2013Date of Patent: May 13, 2014Assignee: Briggs & Stratton CorporationInventors: Carl T. Tiefenthaler, Benjamin R. Miller, Chad J. Gartzke, John R. Schneiker, Greg Hupfer, David W. Branski
