Exhaust purification system of internal combustion engine
摘要：
An internal combustion engine in which an SOx trap catalyst (13) for trapping SOx contained in the exhaust gas contains an oxygen adsorbing and releasing material (54) which can adsorb SO2 contained in the exhaust gas and an SOx storage material (55) which can store SOx in the form of sulfates. The SO2 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 SOx trap catalyst (13) becomes higher than the start temperature of adsorbed SO2 movement, the SO2 which is chemically adsorbed at the oxygen adsorbing and releasing material (54) is oxidized and stored in the form of sulfates in the SOx storage material (55).
摘要（中）：

一种内燃机，其中用于捕集废气中所含的SOx的SO x捕集催化剂（13）含有能够吸附废气中所含的SO 2的氧吸附和释放材料（54），以及能够吸附废气中的SO x储存材料（55） 以硫酸盐的形式存储SOx。 废气中所含的SO 2在氧吸附和释放材料（54）上被化学吸附而不被氧化。 如果SO x捕集催化剂（13）的温度高于吸附SO2运动的起始温度，化学吸附在氧吸附和释放材料（54）上的SO2被氧化并以硫酸盐的形式存储在SOx中 储存材料（55）。
