APPARATUS AND METHOD FOR REGENERATING AN EXHAUST FILTER |
摘要 |
An exhaust gas particulate filter system for an internal combustion engine comprises an exhaust gas conduit in fluid communication with, and configured to receive exhaust gas from, the internal combustion engine. A hydrocarbon supply is connected to the exhaust gas conduit and is in fluid communication with the exhaust gas for delivery of hydrocarbon thereto. A particulate filter assembly is located downstream of the hydrocarbon injector for receipt of the exhaust gas and hydrocarbon mixture. The particulate filter assembly comprises an exhaust gas filter disposed therein for removal of particulates from the exhaust gas and an electrically heated catalyst device disposed therein, upstream of the exhaust gas filter, and heatable to induce oxidation of the exhaust gas and hydrocarbon mixture and to heat the exhaust gas filter and burn particulates collected therein. |
