Patent number: 10329978Abstract: An exhaust system for a marine propulsion device having an engine and a driveshaft housing. An exhaust manifold having a downstream end with an outer surface conveys exhaust gas from the engine. An exhaust conduit having an upstream end with an outer surface conveys the exhaust gas to the driveshaft housing. A flexible coupler couples the downstream end of the exhaust manifold and the upstream end of the exhaust conduit, retaining a gap between them. A metallic coil is aligned with the flexible coupler, which biases the metallic coil into contact with the outer surfaces of the exhaust manifold and the exhaust conduit to conduct heat between them. First and second clamps engage outer surfaces of the flexible coupler to cause inner surfaces of the flexible coupler to sealingly engage the outer surface of the exhaust manifold, and the outer surface of the exhaust conduit, respectively.Type: GrantFiled: February 13, 2018Date of Patent: June 25, 2019Assignee: Brunswick CorporationInventors: Douglas D.

Patent number: 9903251Abstract: An internal combustion engine for an outboard motor comprises a cylinder block having first and second banks of cylinders that extend transversely with respect to each other in a V-shape so as to define a valley there between. An exhaust manifold conveys exhaust gas from the internal combustion engine and is at least partially disposed in the valley. A supporting mechanism supports the exhaust conduit with respect to the internal combustion engine. The supporting mechanism is configured to allow the exhaust conduit to move with respect to the internal combustion engine in 360 degrees in a plane defined by the lateral and transverse axes, and laterally towards and away from the internal combustion engine, thereby facilitating assembly of the exhaust manifold and the internal combustion engine despite positional tolerance differences there between.Type: GrantFiled: November 29, 2016Date of Patent: February 27, 2018Assignee: Brunswick CorporationInventors: David J.

Patent number: 8899029Abstract: Apparatuses for marine propulsion systems having an internal combustion engine comprise an exhaust conduit conveying exhaust from the internal combustion engine; a cooling jacket on the exhaust conduit; and a cooling passage between the exhaust conduit and the cooling jacket. The cooling passage guides flow of cooling liquid from upstream to downstream towards a location where the cooling liquid is mixed with exhaust in the exhaust conduit. First and second baffles are axially spaced apart and extend transversely with respect to the cooling passage so as to disperse the flow of cooling liquid at the location where the cooling liquid is mixed with the exhaust, thereby reducing reversion of cooling liquid in the exhaust conduit. At least one catalyst and at least one oxygen sensor are disposed in the exhaust conduit. The oxygen sensor is adjacent to and oriented parallel to a downstream face of the catalyst so that exhaust flows perpendicularly across the sensor.Type: GrantFiled: December 3, 2012Date of Patent: December 2, 2014Assignee: Brunswick CorporationInventors: Robert Dreyer, Mark J.

Patent number: 6904883Abstract: A line of small internal combustion engines, including twin cylinder engines and single cylinder engines. The engines each include a crankcase, and one or more cylinder members attached to the crankcase, the cylinder members being separate components from the crankcase. A number of different crankcases are provided for various types of single and two cylinder engines, the crankcases having common mounting structure to which the cylinder members may be attached. Thus, the manner in which the cylinder members are attached to the crankcases is the same for each of the different types of crankcases. Two different types of cylinder members are provided, one having a side valve or “L-head” valve train, and the other having an overhead cam (“OHV”) valve train. The cylinder members are therefore modular components which may be selectively used in a variety of different types of engines.Type: GrantFiled: June 2, 2003Date of Patent: June 14, 2005Assignee: Tecumseh Products CompanyInventors: Dale D.
