Abstract: A vehicle exhaust system includes an upstream exhaust component, an intermediate exhaust component, and a downstream exhaust component. The upstream exhaust component is defined by a first outermost diameter and the downstream exhaust component is defined by a second outermost diameter. The intermediate exhaust component is positioned between the upstream and downstream exhaust components and is defined by a third outermost diameter that is greater than the first and second outermost diameters. At least one mixer is located in at least one of the upstream exhaust component, downstream exhaust component, or intermediate exhaust component. An injector is configured to inject fluid into the intermediate exhaust component.

Abstract: An exhaust gas post-treatment device for an internal combustion engine mixes exhaust gas with a reducing agent. The exhaust gas post-treatment device comprises a mixing chamber through which the exhaust gas circulates and a reducing agent sprayer that sprays a reducing agent in the mixing chamber. The reducing agent sprayer comprises at least one first nozzle and at least one second nozzle, where said at least one first nozzle is designed to produce small droplets, and said at least one second nozzle is designed to produce large droplets.
