Abstract
An exhaust gas treatment system is provided, having an internal combustion engine, an exhaust gas conduit, an electrically heated catalyst ('EHC') device, an oxidization catalyst ('OC') device, an OC temperature sensor, a hydrocarbon (“HC”) adsorber, and a control module. The hydrocarbon supply is selectively activated for delivery of a hydrocarbon and formation of an exhaust gas and hydrocarbon mixture therein. The EHC device is selectively activated to produce heat and induce oxidization. The OC device is in fluid communication with the exhaust gas conduit and located downstream of the EHC device. The OC temperature sensor is in fluid communication with the exhaust gas conduit and located downstream of the OC device. The HC adsorber is located downstream of the EHC device. The control module is in communication with the hydrocarbon supply, the EHC device, the OC device, the OC temperature sensor, and the HC adsorber.
