An after treatment system (ATS) for a vehicle includes, fluidly connected in series, an inlet, a urea mixer and an outlet. The inlet is fluidly connected to an output of an engine of the vehicle and the outlet is fluidly connected to an outlet tube of the vehicle. The urea mixer is provided with a dosing module, an inner element and an outer element. The inner element is configured such that a first flow of exhaust gas flow flowing from the inlet into the urea mixer flows into an first volume defined by the inner element. The outer element is configured such that a second flow flows in a volume defined between inner element and outer element, wherein the first and second flows rejoin together in a mixing chamber fluidly connected to the volume and to the first volume downstream with respect inner and outer elements.

Operating a machine system for co-production of electrical power and filtered potable water includes operating an electrical generator by way of rotation of an engine output shaft to produce electrical power, and collecting water condensed from cooled treated exhaust from the engine for delivery to an outgoing water conduit. Operating the machine system further includes supplying electrical power produced by the electrical generator to an in situ electrical load, and to at least one ex situ electrical load such as a power grid. The in situ electrical load is produced by at least one of an exhaust conveyance device, an air conveyance device, or a water conveyance device in a water subsystem.

A vehicle tank for receiving a liquid medium, encompassing: a tank body having a tank wall; a heat exchanger arranged in an interior of the tank body, the heat exchanger having a first heat-exchanger heat delivery surface that faces toward the tank wall and is spaced away from the tank wall; and an electric heating apparatus that is arranged in the interior of the tank body, the electric heating apparatus being arranged between the first heat-exchanger heat delivery surface and the tank wall.

In an exhaust heat recovery structure, a heat exchange portion (a tubular part) is configured such that a height of a lower inner surface is lowered from an inlet toward an outlet. Hence, when exhaust gas is condensed and condensed water is thereby generated inside the heat exchange portion (the tubular part), the condensed water flows from the inlet side toward the outlet side where the lower inner surface is lowered, and is then discharged to a piping part. Accordingly, the condensed water is unlikely to be collected inside the heat exchange portion.

An assembly for use in treating gaseous exhaust emissions has an inductive heater mounted next to a gaseous emissions treatment unit. and downstream substrate units or upstream and downstream sections of a single substrate. The upstream unit or section has linear passages extending the length of the first substrate body for the passage of emissions gas but with some of the passages blocked by metal inserts for use in inductive heating of the upstream unit. The concentration of metal inserts is high and the metal inserts are distributed to enable rapid intense inductive heating of the slice or section to achieve light off temperature rapidly in order to pass heat-supplemented gaseous emissions at light-off temperature to the downstream substrate or section as quickly as possible.

A catalyst body for an electrically heated catalyst has an electrical contacting assembly, which is arranged on the catalyst body and comprises an electrical conductor embedded in the catalyst body and extending in a longitudinal direction of the catalyst body and at least up to one end face of the catalyst body.

An exhaust system for the aftertreatment of exhaust gases of an internal combustion engine, having an annular catalytic converter which is flowed through by exhaust gas, wherein the annular catalytic converter has an inflow point and an outflow point and the annular catalytic converter has a tubular first flow path and an annular second flow path which are oriented concentrically with respect to one another and which are flowed through in series, wherein the first flow path is surrounded to the outside in a radial direction by the second flow path, wherein a pipe is led in the radial direction from the outside through the second flow path, wherein the pipe opens into the annular catalytic converter and the pipe has a radial extent at least as far as into the inner first flow path.

Methods and systems are provided for an exhaust-gas aftertreatment device. In one example, an exhaust-gas aftertreatment device comprises a housing with a first can comprising a first catalytic converter and a second can comprising a second catalytic converter, wherein the first catalytic converter is not concentric with the first can.

A component of an exhaust gas system and a method for exhaust gas after-treatment having a housing with an inlet and an outlet for an exhaust gas, an annular heat exchanger through which the exhaust gas can flow from the inlet in an axial direction and along a first flow path. Downstream of the heat exchanger, an annular catalyst body is arranged inside the heat exchanger and through which the exhaust gas can flow in a radial direction, such that, downstream of the catalyst body, the exhaust gas flows through the heat exchanger in the radial direction and along a second flow path.

A catalytic converter for an internal combustion engine has a housing (2) and a catalyst element (12) formed in the housing (2). The housing (2) is formed such that exhaust gas of the internal combustion engine can flow through the housing (2). The catalyst element (12) is formed such that fluid can flow around and through it. Additionally, the catalyst element (12) has a plurality of ribs (15) on its surface (14) that faces the exhaust gas.
