Beschreibung
Zusammenfassung:	A diesel engine exhaust gas aftertreatment system is described. The system may comprise a heat transfer device comprising a first side and a second side; a heater downstream of the first side of the heat transfer device, a filter downstream of the heater; and, an exhaust path downstream of the filter leading to the second side of the heat transfer device, wherein the exhaust path is isolated from an external surface of the filter to inhibit heat transfer from the heated exhaust gas exiting the filter to the external surface of the filter.
