摘要： An oceangoing vessel exhaust pipe coupling used to temporarily couple to an oceangoing vessel exhaust pipe. Installation and removal of the coupling only requires a simple mechanism with three translational degrees of freedom and one rotational degree of freedom, thereby enabling remote coupling. The coupling adapts to a wide array of exhaust pipe shapes and sizes. This is accomplished by a unique shape that allows stable and balanced resting position on top of an exhaust pipe as well as a two-chamber configuration, wherein the two chambers are separated by a permeable partition. Furthermore, the unique shapes of the chambers deflect the exhaust gas stream towards the outlet of the coupling, regardless of exhaust pipe style, thereby increasing capture efficiency and extending the life of an attached fabric flexible hose.

摘要： An exhaust gas recirculation system is provided for an internal combustion engine having reciprocating piston design with an exhaust gas turbocharger unit having an exhaust gas turbine and a supercharger. The internal combustion engine has a machine housing accommodating one or more cylinders having reciprocating pistons, which is provided with a suction unit and an exhaust gas outlet unit, which is connected to the exhaust gas turbine by way of an exhaust gas line. The exhaust gas line supplies at least a part of the exhaust gas stream to the suction unit via the exhaust gas recirculation system. To optimize the exhaust gas recirculation system, it has a pipe branch, which is connected to the exhaust gas line and is connected to an exhaust gas recirculation line with a control element interconnected. The exhaust gas recirculation line extends, on the one hand, with a first supply line section outside and, on the other hand, with a second supply line section in an interior of, a suction unit container of the suction unit. An exhaust gas stream is conveyed by the second supply line section into the suction unit container for targeted mixing of exhaust gases with the air volume contained in the suction unit container.

摘要： A water jet propelled water craft has a jet pump impeller (24) mounted in a jet tube (18) and driven by a water cooled engine (16). A heat exchanger (30′) for the engine coolant is incorporated into a housing for the jet pump impeller (24) and takes the form of a chamber surrounding a through bore of the jet tube (18). The chamber has an inlet and an outlet for the flow of coolant and contains a series of staggered baffles that define an oscillatory and circumferential flow path for the coolant between the inlet and outlet.

摘要： An outboard engine is disclosed that includes an idling chamber that communicates with a guiding outlet of a first exhaust path and that is open to the atmosphere. The idling chamber includes a cooling water communicating path that communicates with a cooling water supplying path, and a pressure adjusting valve that opens the cooling water communicating path when the value of the water pressure in the cooling water supplying path reaches a threshold value. When the value of the water pressure in the cooling water supplying path reaches the threshold value, the pressure adjusting valve opens and a portion of cooling water is guided to the idling chamber through the cooling water communicating path.

摘要： A control system for an outboard motor provides an EGR valve and an idle exhaust relief valve which are under the control of a controller that opens and closes the valves as a function of the rotational speed of a crankshaft of the engine. The EGR valve controls the flow of exhaust gas from an exhaust gas conduit to an air intake manifold. The idle exhaust relief valve controls the flow of exhaust gas from the exhaust conduit to a location at atmospheric pressure. In addition, the idle exhaust relief valve is used to allow air to flow from the atmosphere into the exhaust conduit when the engine is turned off.

摘要： An exhaust system for a small watercraft for effectively reducing exhaust noise and allowing a high output of an engine to be easily obtained at the time of high speed operation. An exhaust outlet of an exhaust pipe extending from an engine provided in a watercraft body is disposed at a position that allows it to sink in the water at the time when a travel speed of the watercraft body is a predetermined speed or less. The exhaust outlet is raised above the water at the time when the travel speed of the watercraft body exceeds the predetermined speed. An open surface of the exhaust outlet is offset toward a side wall surface of a pump chamber from a center of a jet pump in the pump chamber and is made oblique toward the side wall surface toward which the open surface of the exhaust outlet is offset.

摘要： An exhaust system for a marine gas turbine may suppress a reduction of an efficiency even if a space therefor is small. In the exhaust system for a marine gas turbine, in which an end portion of an exhaust diffuser 2 is assembled into an exhaust chamber 1 connected with an upper exhaust eductor 4, the end portion of the exhaust diffuser 2 is disposed in the vicinity of an inlet of the exhaust chamber 1. An outlet 2a of the exhaust diffuser is slanted so that an upper portion of the outlet of an end of the exhaust diffuser is located upstream of a lower portion of the outlet. As a result, the exhaust gas may readily flow around and into the exhaust eductor 4.
