    摘要: A power system and a method for energizing an electrically heated catalyst are provided. The system includes a controller that generates a first control signal to set a switching device to a first operational state if the first temperature level downstream of the catalyst is less than a threshold temperature level and the engine is being decelerated. The controller further generates a second control signal to induce a generator to output a second voltage if the first temperature level is less than the threshold temperature level and the engine is being decelerated, such that the second voltage is applied through the switching device in the first operational state to the catalyst to increase a temperature of the catalyst.

The flow-through container of absorbent particles is in fluid communication with the exhaust gas conduit and configured to receive the exhaust gas. The flow-through container substantially adsorbs the water from the exhaust gas below a threshold temperature. The EHC device is in fluid communication with the exhaust gas conduit and is configured to receive the exhaust gas. The EHC device is located downstream of the flow through container, and is selectively activated to produce heat.
