    • An exhaust emission control system of an internal combustion engine includes: a bypass passage (22) provided in an exhaust passage (14) of the engine and arranged to bypass a main passage (16) as a part of the exhaust passage, a NOx adsorbent (28) provided in the bypass passage and adapted to adsorb at least NOx as one of components contained in exhaust gas, a channel switching device (30) that switches a channel of the exhaust gas between the main passage and the bypass passage, an adsorption control device (50) that controls the channel switching device, based on operating conditions of the engine, so as to cause the exhaust gas to flow through the bypass passage, and an adsorbing capability determining device (50) that determines, when the adsorbing capability of the NOx adsorbent degrades, whether the degradation in the adsorbing capability is a surmountable degradation from which the NOx adsorbent can recover, or an insurmountable degradation from which the NOx adsorbent cannot recover.
    • 内燃机的废气排放控制系统包括:设置在发动机的排气通路(14)中的旁通通路(22),其布置成绕作为排气通道的一部分的主通道(16),NOx吸附剂 (28),其设置在所述旁通通路内,并且至少吸附作为废气中的成分中的一种的NOx;通道切换装置(30),其在所述主通路与旁通通路之间切换排气的通道,吸附 控制装置(50),其基于发动机的运转条件控制所述通道切换装置,以使所述排气流过所述旁通通路;吸附能力判定装置(50),其在吸附能力 的NOx吸附剂的劣化,NOx吸附剂能够回收的难以降解的吸附能力的劣化,NOx吸附剂不能再次的不可克服的劣化 盖。
