EXHAUST APPARATUS

摘要

Exhaust apparatus (100) is disclosed comprising an inlet (101) for receiving input exhaust gas; a heater (105) adapted to heat part of the input exhaust gas with the remaining input exhaust gas bypassing the heater; a first catalyst stage (106) adapted to oxidise exhaust gas heate by the heater (105); a second catalyst stage (109) adapted to oxidise a mixture of the input exhaust gas which bypassed the heater (105) and exhaust gas oxidised by the first catalyst stage (106); and a particulate trap (110) adapted to trap particulates in exhaust gas output from the second catalyst stage (106).
