A condensate discharge system for an exhaust gas measuring device. The condensate discharge system includes a condensate separator in which a positive pressure prevails, an outflow line in which atmospheric pressure prevails, a connecting line, and an intermediate reservoir in which the positive pressure prevails. The intermediate reservoir is arranged between the condensate separator and the outflow line and is directly connected to the condensate separator via the connecting line. The intermediate reservoir includes a float valve via which a condensate is dischargeable into the outflow line.

A water neutralization system that includes a first source of water that is acidic and a second source of water that is basic. A storage reservoir communicates with each of the first source and the second source, and includes a pH sensor that is configured to transmit a signal indicative of a pH of the water stored in the storage reservoir. At least one valve controls fluid communication between the storage reservoir and at least one of the first source and the second source, and a controller communicates with each of the pH sensor and the valve. Based on the signal indicative of the pH of the water stored in the storage reservoir, the controller instructs the valve to adjust an amount of water received from at least one of the first source and the second source to neutralize a pH of the water stored in the storage reservoir.

An exhaust pipe structure includes a first pipe portion, a second pipe portion, and a third pipe portion. The first pipe portion is arranged below a floor panel of the vehicle, and extends in a horizontal direction in a vehicle side view. The second pipe portion communicates with a front end of the first pipe portion, and has a bottom portion recessed downward below a lower end of the front end and a top portion protruding downward below an upper end of the front end. The third pipe portion communicates with a rear end of the first pipe portion, and has a bottom portion recessed downward below a lower end of the rear end and a top portion protruding downward below an upper end of the rear end.

Methods and systems are provided for removing moisture from an engine exhaust system. In one example, a method includes, during a vehicle key-off condition, in response to a higher than threshold exhaust moisture level and a lower than threshold engine run time during an immediately prior drive cycle, operating an electric air compressor to remove the moisture accumulated in the exhaust manifold.

An internal combustion engine, ICE, system for a vehicle includes an ICE operable on hydrogen; an exhaust gas aftertreatment system, EATS, arranged in an exhaust gas circuit downstream the ICE, said EATS having at least one NOx reduction device and/or a particulate filter, and an exhaust gas water recovery, EWR, system arranged at least partly downstream the EATS in the exhaust gas circuit, said EWR system having at least a primary exhaust cooler and a water separator; a waste heat recovery, WHR, system for providing a rankine cycle, said WHR system being arranged to transport a working fluid, WF, through the primary exhaust cooler of the EWR system; a low temperature coolant circuit in fluid communication with an exhaust condenser of the EWR system; and a water management system arranged to collect water from the EWR system and transport water to at least one combustion chamber of the ICE.

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.

A system includes an engine and an exhaust conduit in communication with the engine. A water separation device has exhaust gas passageways in communication with the exhaust conduit. The water separation device has a substrate and a membrane on the substrate. The substrate is monolithic and extends around the exhaust gas passageways. The membrane is between the exhaust gas passageways and the substrate and has capillary condensation pores extending from the exhaust gas passageways to the substrate.

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 exhaust gas treatment device including an outer housing including a first inflow part and a second inflow part, an inner housing provided in the outer housing and having a gas inflow part, a guide channel defined between the outer housing and the inner housing and configured to guide a part of the first exhaust gas to the gas inflow part, and a spiral member including a barrel part provided in the inner housing and configured to define a passage flow path, a spiral protrusion provided on an outer surface of the barrel part and configured to define a spiral flow path between the barrel part and the inner housing, and a gas discharge part provided in the barrel part and configured to discharge the first exhaust gas and the second exhaust gas, which have passed through the spiral flow path, to the passage flow path.

A metering device for metering water or an aqueous solution, such as an injector for metering a reducing agent liquid into an exhaust gas stream of a combustion system or an injector for metering water or aqueous solution into a combustion chamber or into an intake manifold of an internal combustion engine. The metering device has an inlet and an outlet for the water or aqueous solution and a shut-off device which is arranged between the inlet and the outlet. At least one electrically operated heating element is arranged in the region of the shut-off device so as to heat and avoid freezing of the liquid.
