A marine propulsion device includes an engine, an exhaust pipe to allow exhaust gas of the engine to pass through the exhaust pipe, and a cooling water supply passage to supply cooling water for the engine into the exhaust pipe toward a downstream side in a flow direction of the exhaust gas and cause the cooling water to flow circumferentially along an inner peripheral surface of the exhaust pipe.

A fluid injection system for a gas turbine engine may comprise a fluid injector configured to inject a fluid into an exhaust flow exiting a turbine section of the gas turbine engine. The fluid injector may be coupled to a turbine exit guide vane located at a forward end of an exhaust system of the gas turbine engine. The fluid may decrease a temperature of the exhaust flow exiting the turbine section and/or increase a thrust of the gas turbine engine.

A method for controlling the saturation level of gas in a liquid discharge includes obtaining temperature and pressure measurements of a solvent in a mixing vessel and obtaining a pressure measurement of a source feedstock in a feedstock tank, correlating the temperature and pressure measurements of the solvent to baseline data to generate a theoretical uptake rate for the source feedstock into the solvent and a theoretical flow rate of the source feedstock into the mixing vessel, and determining a required opening setting for a feedstock valve in the feedstock input line in order to achieve a desired liquid displacement in the mixing vessel. The method includes determining an uptake duration and achieving an uptake displacement equivalent to the reverse of the desired liquid displacement. The method includes generating a valve operating control law for how the feedstock valve should function in a cycle.
