Abstract (en)
[origin: WO2007132334A2] A PM sensor (62) for measuring particle matter in exhaust gas is disposed between a three-way catalyst (49) and a muffler (5) in an exhaust pipe (47), and has an oxidation catalyst (71) and an electrical heater (72) that are stacked together, and a temperature sensor (73) that measures a temperature of the oxidation catalyst (71) interposed between the oxidation catalyst (71) and the electrical heater (72). The oxidation catalyst (71) carries a ceria as an oxygen-storing agent that occludes oxygen in the exhaust gas, and a ECU (51) calculates a sediment amount of the exhaust particulate matter based on an amount of temperature rise when the electrical heater (72) heats the oxidation catalyst (71) and an accumulated value of an intake air amount.
