A power system for converting waste heat from exhaust gases of an internal combustion engine to electrical energy includes an aftertreatment assembly positioned within a first housing. The power system includes an evaporator assembly positioned within a second housing. The evaporator assembly is positioned directly adjacent the aftertreatment assembly. The evaporator assembly includes a first portion of a working fluid loop in thermal communication with a first length of an exhaust conduit that extends from the aftertreatment assembly into the second housing. The power system includes a power pack positioned longitudinally forward of the aftertreatment assembly. The power pack includes a tank, a condenser, a pump and an expander fluidly connected by a second portion of the working fluid loop. The second portion is fluidly connected to the first portion of the working fluid loop.

Rankine power system for use with exhaust gas aftertreatment system

A power system for converting waste heat from exhaust gases of an internal combustion engine to electrical energy includes an aftertreatment assembly positioned within a first housing. The power system also includes an evaporator assembly positioned within a second housing. The evaporator assembly is positioned directly adjacent the aftertreatment assembly. The evaporator assembly includes a first portion of a working fluid loop in thermal communication with a first length of an exhaust conduit that extends from the aftertreatment assembly into the second housing. The power system also includes a power pack positioned inside a third housing. The power pack is positioned directly adjacent the evaporator assembly opposite to the aftertreatment assembly. The power pack includes a tank, a condenser, a pump and an expander fluidly connected by a second portion of the working fluid loop. The second portion is fluidly connected to the first portion of the working fluid loop.

An exhaust-gas module A for an internal combustion engine, which exhaust-gas module has a base housing having a first side wall, at least one second side wall, an inlet for connection to the internal combustion engine and at least one outlet, wherein the inlet is arranged in the first side wall, and having multiple exhaust-gas purification components which are arranged in the base housing, wherein at least one SCR and/or one DOC are/is provided, wherein the at least one outlet is arranged in the second side wall and serves for the connection of an exhaust tailpipe of the internal combustion engine and/or alternatively for the coupling of an attachment housing, wherein the rest of the base housing, with the exception of the second side wall, is formed without outlets, wherein a connection contour with a circumferential contour Uwhich has a basic shape Gis provided for the connection of the attachment housing, wherein the connection contour delimits the second side wall at the edge, wherein at least one of the exhaust-gas purification components DPF, NH3, LNT, HOH is present in the base housing, and/or wherein at least one auxiliary component such as a mixer, an injector or a burner is present in the base housing.
