sistema de purificação de exaustão de um motor de combustão interna. |
摘要 |
An internal combustion engine in which an SO x trap catalyst (13) for trapping SO x contained in the exhaust gas contains an oxygen adsorbing and releasing material (54) which can adsorb SO 2 contained in the exhaust gas and an SO x storage material (55) which can store SO x in the form of sulfates. The SO 2 which is contained in the exhaust gas is chemically adsorbed at the oxygen adsorbing and releasing material (54) without being oxidized. If the temperature of the SO x trap catalyst (13) becomes higher than the start temperature of adsorbed SO 2 movement, the SO 2 which is chemically adsorbed at the oxygen adsorbing and releasing material (54) is oxidized and stored in the form of sulfates in the SO x storage material (55). |
