摘要： A system includes an engine defining a water jacket fluidly coupled to a heat exchanger. An exhaust manifold defines an exhaust manifold cooling passage. A pump is fluidly coupled to the water jacket, and to each of the heat exchanger and the exhaust manifold cooling passage. An engine cooling circuit includes the water jacket, the heat exchanger, and the pump. An exhaust cooling circuit is selectively fluidly coupled to the engine cooling circuit. The exhaust cooling circuit includes the water jacket, the exhaust manifold cooling passage, and the pump. A control valve includes an inlet fluidly coupled to a first portion of the water jacket. A first outlet is fluidly coupled to a second portion of the water jacket. A second outlet is fluidly coupled to the exhaust cooling circuit. The control valve is structured to selectively control flow of coolant fluid through the second outlet.

摘要： A catalyst device includes a catalyst carrier serving as a heating element that generates heat when energized. The catalyst device includes a guide pipe that guides exhaust into the case. The catalyst device includes a connecting pipe that connects the guide pipe to the case. The case has an end that is an insulative portion and projects further upstream, in the direction in which exhaust flows, from an end surface of the catalyst carrier. A temperature difference inducing structure, which induces a state in which the connecting pipe is relatively lower in temperature than the end of the case, includes a heat shield, encompassing an outer circumferential surface of the connecting pipe and having an opening in part of a portion opposing the outer circumferential surface of the connecting pipe, and a stay fixing the outer circumferential surface of the connecting pipe to an internal combustion engine.

摘要： An exhaust conduit for a marine exhaust system includes an inlet end portion connectable to an exhaust manifold, an outlet end portion that directs exhaust gases toward an exhaust system outlet, a catalytic converter assembly arranged between the inlet and outlet end portions, and inner and outer tubes. The inner tube directs exhaust gases from the exhaust manifold to the catalytic converter assembly, and the outer tube surrounds the inner tube to define a cooling liquid passage between the inner and outer tubes. A flange is secured to the inner and outer tubes at inlet ends thereof, the flange being connectable to an outlet of the exhaust manifold. The inner tube has a uniform diameter between the flange and the catalytic converter assembly, and is welded to the flange independently of the outer tube. First and second welds join the inner and outer tubes to the flange at radially inner and outer faces, respectively, of a flange rim.

摘要： A method is disclosed for optimizing fuel economy during an engine warm up phase of operation of an internal combustion engine. An exhaust manifold may have a coolant jacket through which a coolant may flow. A temperature of the coolant in the exhaust manifold may be determined to detect when it is at a predetermined maximum threshold, which represents a temperature threshold just below a temperature at which the coolant will begin to boil. When this threshold is reached, then a determination may be made as to a minimum rate of flow of the coolant through the exhaust manifold which maintains the coolant at about the predetermined maximum threshold, and the coolant may be flowed through the exhaust manifold at the determined minimum rate of flow.

摘要： An exhaust system is for a marine propulsion device having an internal combustion engine. A catalyst housing has a housing inlet end that receives an exhaust gas flow from the internal combustion engine into the catalyst housing and an opposite, housing outlet end that discharges the exhaust flow out of the catalyst housing. A catalyst is disposed in the catalyst housing. The catalyst has a catalyst inlet end that receives the exhaust gas flow and an opposite, catalyst outlet end that discharges the exhaust gas flow. A catalyst mantel is on an outer periphery of the catalyst. The catalyst mantel has a mantel inlet end and an opposite, mantel outlet end. A radial flange is on at least one of the mantel outlet end and mantel inlet end. A connector mates with an inner diameter of the catalyst housing. The radially extending flange of the catalyst mantel is axially sandwiched between the connector and a radially inner shoulder of the catalyst housing.

摘要： An elongated exhaust conduit comprises a first end receiving hot exhaust gas from a marine engine and a second end discharging the exhaust gas. An elongated cooling water jacket extends adjacent to the exhaust conduit. The cooling water jacket conveys the raw cooling water adjacent to the exhaust conduit to thereby cool the exhaust conduit and warm the raw cooling water therein and discharges the warmed cooling water to cool the marine engine. The cooling water jacket comprises first and second channels that are separate from each other. The cooling water is oriented in a helical flow around the exhaust conduit.

摘要： A water jacket is attached to an exhaust manifold connected to an exhaust port to annularly cover an outer side of an exhaust channel in the exhaust manifold. An engine cooling coolant is made to flow as a cooling medium of the water jacket of the exhaust manifold. An exhaust pipe in a siphon shape is connected to the exhaust manifold, a water jacket is attached so as to annularly cover an outer side of a front half portion of the siphon shape, and seawater is directly supplied into the water jacket to flow therein. Consequently, an exhaust device of an outboard motor practically having a compact structure and excellent exhaust performance and accordingly realizing excellent engine performance is provided.
