FILTER REPROCESSING APPARATUS FOR INTERNAL COMBUSTION ENGINE

摘要

PURPOSE:To provide a filter reprocessing apparatus for catching particulates in exhaust gas from a diesel engine which heats and reprocesses the filter while a temperature of the filter being reprocessed for the particulates is low. CONSTITUTION:A filter reprocessing apparatus comprises a heating chamber 18 provided in an exhaust pipe 17 for discharging exhaust gas of an internal combustion engine 16, a filter 19 received in the heating chamber 18 to catch particulates contained in the exhaust gas, a micro-wave generating means 20 to generate the microwave for electrifying the heating chamber, an opening part 23 opened while the microwave generating means 20 is operated and communicating to the heating chamber to be opened and closed and a an exhaust bypass pipe 27 to bypass the exhaust gas from the exhaust pipe 17. The particulates caught by the filter 19 are reprocessed and burnt by utilizing the permeation of the microwave and gently burnt by air supplied through natural convection.
