The present invention relates to an aircraft having at least one wing, on which at least one propulsion unit is arranged, comprising at least one heat engine, especially a gas turbine, as well as an exhaust gas passage for conducting exhaust gas of the heat engine into and inside the wing.

System (1) for the purification of exhaust gases (S) of an endothermic engine (100), comprising at least one duct (2) for exhausting the gases produced by said endothermic engine, means (3) for cooling said exhaust gases which cross said duct (2) so that to cause, at least in part, the condensation of the water vapor contained in said exhaust gases in water (AC), and means (4) for separating the condensed water (AC), which is condensed by said cooling means along the exhaust duct, from the exhaust gases and for deviating it along a secondary duct (10), said system being characterized by further comprising filtering means (5), which are arranged downstream of said separating means (4) along said secondary duct (10), for filtering said condensed and separated water (AC).

An embodiment control device for discharging condensed water includes a signal receiver configured to receive a power-starting off signal, a temperature receiver configured to receive outdoor air temperature information, and a controller configured to perform a condensed water discharge mode maintaining an engine under an idling condition during a preset power-starting maintenance period in response to the power-starting off signal being received by the signal receiver and the outdoor air temperature information received from the temperature receiver being equal to or lower than a set temperature value.

This disclosure relates generally to a prime mover system. More specifically, this disclosure relates to a prime mover exhaust system that can prevent the accumulation of debris (e.g., soot or unburned fuel) in the prime mover system. In accordance with at least one embodiment described and recited herein, a self-cleaning prime mover exhaust system is provided. The prime mover exhaust system includes an exhaust tip, an exhaust pipe, and a cleaning tube. The exhaust tip is configured to eject exhaust out of the prime mover exhaust system, the exhaust pipe is configured to direct the exhaust away from a prime mover, and the cleaning tube is configured to accumulate debris exiting from the exhaust pipe and configured to vacuum the debris out of the self-cleaning prime mover exhaust system through the exhaust tip using the Venturi effect.

A system for mobile carbon capture, preferably including a capture module, a regeneration module, and a storage module 130. The system can optionally include a thermal control module and/or a dehumidifier. A method for mobile carbon capture, preferably including adsorbing a target species, desorbing the target species, and storing the target species. The method can optionally include pre-treating input gas, offloading stored species, and/or regenerating desiccators.

A bottoming cycle power system includes a turbo-expander operable to rotate a turbo-crankshaft as a flow of exhaust gas from a combustion process passes through the turbo-expander. A turbo-compressor is operable to compress the flow of exhaust gas after the exhaust gas passes through the turbo-expander. An open cycle absorption chiller system includes an absorber section operable to receive the flow of exhaust gas from the turbo-expander and to mix the flow of exhaust gas with a first refrigerant solution within the absorber section. The first refrigerant solution is operable to absorb water from the exhaust gas as the exhaust gas passes through the first refrigerant solution. The absorber section is operable to route the flow of exhaust gas to the turbo-compressor after the flow of exhaust gas has passed through the first refrigerant solution.

A system for removing dust from exhaust gas, comprising a dust removing system inlet, a dust removing system outlet, and an electric field apparatus (1021). The electric field apparatus (1021) comprises an electric field apparatus inlet, an electric field apparatus outlet, a dust-removing electric field cathode (10212) and a dust-removing electric field anode (10211). The dust-removing electric field cathode (10212) and the dust-removing electric field anode (10211) are used to generate an ionizing electric field for dust removal. When a certain amount of dust has accumulated on the electric field apparatus, the electric field apparatus performs a black carbon removal process, thereby avoiding a reduced electrode gap resulting from an increased thickness of black carbon.

A muffler may include a thin plate mesh provided in an internal space of an inlet chamber formed at a side opposite to an outlet chamber of a muffler housing such that gas contained in exhaust fluid passes through the thin plate mesh by collision of the exhaust fluid against the thin plate mesh and water contained in the exhaust fluid is separated from the gas; a water movement guide fluidically-connected to the inlet chamber and the outlet chamber for allowing the water gathered at the front side of the thin plate mesh in the internal space of the inlet chamber to flow therein and move to the outlet chamber; and a muffler pipe connected to the inlet chamber and the outlet chamber for allowing the gas gathered at the rear side of the thin plate mesh in the internal space of the inlet chamber to move to the outlet chamber.

A piston arrangement for a clean combustion engine, such as a hydrogen engine. The piston arrangement comprises a piston configured for reciprocal movement inside a cylinder having a cylinder wall, the piston having a piston head configured to face a first compartment with pressurized gas, a sealing arrangement comprising at least one sealing ring configured to be arranged to seal the piston to the cylinder wall and separating the first compartment from a second compartment, and a water channel extending from an interior of the piston to the sealing ring to provide water for lubricating the sealing ring. The piston head comprises a pumping element configured to be arranged to pressurize the water in the water channel by pressurised gas in the first compartment.

Oil console equipment includes: a lubrication oil tank in which a lubrication oil is stored; a lubrication oil supply line which is connected to the lubrication oil tank and through which a liquid lubrication oil stored in the lubrication oil tank is supplied to a bearing supporting a rotor; a first cooler which is provided in the lubrication oil supply line and cools the liquid lubrication oil supplied to the bearing; a lubrication oil recovery line which is connected to the lubrication oil tank and through which the lubrication oil recovered from the bearing is introduced into the lubrication oil tank; a first atmosphere discharge pipe which is connected to the lubrication oil tank and through which a lubrication oil mist which exists in a gas phase in the lubrication oil tank and is a misted lubrication oil and a first exhaust gas containing a gas are introduced out.
