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.

An injection structure using integrated exhaust heat recovery system (EHRS) condensate, the structure including an integrated heat exchange part connected to an engine of a vehicle and branched from an exhaust outlet of an exhaust manifold to integrate exhaust gas recirculation (EGR) and EHRS, a condensate circuit part extended from a rear end of the integrated heat exchange part to the engine of the vehicle and configured to move exhaust gas condensate, a three-phase valve configured to open and close so that a low-temperature coolant is selectively introduced into the integrated heat exchange part according to operating conditions, an EGR valve configured to open and close so that EGR gas with filtered condensate flows into the engine of the vehicle, a bypass valve fluidly connected to an exhaust muffler, and a controller configured to control opening and closing of the three-phase valve, the EGR valve, and the bypass valve according to the operating conditions.

The present invention provide a method for purifying exhaust gas in which nitrogen oxides (NOx) gas is removed from a combustion exhaust gas. The method for purifying exhaust gas according to the invention is characterized in that water vapor is further added to raw exhaust gas to be processed to increase the water vapor concentration in the exhaust gas and the resulting moisture-adjusted exhaust gas is introduced into a denitration catalyst layer. The water vapor concentration in the moisture-adjusted exhaust gas is preferably 22.0% by volume or less in the total of the water vapor originally contained in the raw exhaust gas and the added water vapor.

An exhaust treatment system includes a dust-removal system. The dust-removal system has an electric field device (1021) and an exhaust cooling device. The electric field device (1021) includes an inlet of the electric field device, an outlet of the electric field device, a dust-removal electric field cathode (10212), and a dust-removal electric field anode (10211), the dust-removal electric field cathode (10212) and the dust-removal electric field anode (10211) being used for generating an ionization dust-removal electric field. The exhaust cooling device is used for reducing an exhaust temperature before the inlet of the electric field device. An exhaust dust-removal system facilitates to reduce greenhouse gas emission, and also facilitates to reduce hazardous gas and pollutant emission, so that gas emission is more environment-friendly.

An exhaust-gas aftertreatment device for an internal combustion engine, for use in a motor vehicle, includes an exhaust tract with at least one exhaust pipe and at least one exhaust-gas aftertreatment element. The exhaust-pipe internal wall and/or the at least one exhaust-gas aftertreatment element have/has a vapor-sorbing material forming at least one exhaust-tract-side sorption element.

An exhaust gas heat exchanger, in particular for use in a motor vehicle, having at least one first flow channel that conducts a first fluid, which first flow channel is accommodated in respective tube sheets at end areas of the first flow channel. A housing surrounds the first flow channel and forms a second flow channel for a second fluid that flows through the housing and flows around the first flow channel. Pipe sheets are inserted into the housing such that the first flow channel is sealed off from the second flow channel. A first diffuser conducts the first fluid into the first flow channel and a second diffuser conducts the first fluid out of the first flow channel. A first shielding element has a first passage and a first spacing element is placed onto a tube sheet from the side facing away from the first flow channel.
