EXHAUST GAS AFTERTREATEMENT SYSTEM AND METHOD OF OPERATION |
摘要 |
An exhaust gas after treatment system for an internal combustion engine comprises an oxidation catalyst device having a first substrate, a heater, and a second substrate disposed serially between the inlet and the outlet. A hydrocarbon supply is connected to and is in fluid communication with the exhaust system upstream of the oxidation catalyst device for delivery of a hydrocarbon thereto. The heater is configured to oxidize the hydrocarbon therein and to raise the temperature of the second substrate and exhaust gas passing therethrough.
