Beschreibung
Zusammenfassung:	A vehicle exhaust system includes a conduit defining an exhaust gas flow path extending along a center axis, and wherein the conduit includes a doser opening. An exhaust gas aftertreatment component is positioned downstream of the conduit and at least one doser is configured to inject fluid into the conduit through the doser opening. A heating element pre-heats the fluid prior to mixing with exhaust gas. A perforated pipe is positioned within the exhaust gas flow path to surround the fluid injected by the doser.
