摘要： In a catalyzer arrangement in an exhaust system of a multi-cylinder internal combustion engine (1), each of exhaust pipes (4-7) connected with exhaust ports of the engine has a first exhaust pipe section (4a-7a) extending away from a main body of the engine, a second exhaust pipe section (4b-7b) contiguous to the first exhaust pipe section (4a-7a) having a first curved portion (4k-7k) for turning the second exhaust pipe section toward the main body of the engine, and a third exhaust pipe section (4c-7c) contiguous to the second exhaust pipe section having a second curved portion for turning the third exhaust pipe portion away from the main body of the engine. A catalyzer (8,9) is connected to a downstream side of the third exhaust pipe section and disposed within a space (A) surrounded by the first, second and third exhaust pipe sections. The exhaust pipes are divided into one group positioned near one end of a row of cylinder of the engine and another group positioned near another end of the row of cylinder. Exhaust pipes of the one group and exhaust pipes of the another group are collected into respective collective exhaust pipes at a portion extending over the second and third exhaust pipe sections or at the third exhaust pipe section.

摘要： When deterioration of a NOx purifying device due to sulfur contamination is detected, a specific operating state flag FHL is set to "1," and, at intervals equal to or shorter than, for example, three seconds, the air-fuel ratio of an air-fuel mixture to be supplied to an engine is varied so that it is alternately leaner and richer than the stoichiometric air-fuel ratio. When the temperature TCAT of the NOx purifying device exceeds a deterioration recovery temperature STCAT2 while the air-fuel ratio variation control is being executed, the SOx removing flag FHLSOx is set to "1," and for a period equivalent to the deterioration recovery time TRSOx, the air-fuel ratio is maintained richer than the stoichiometric air-fuel ratio.

摘要翻译：当检测到由于硫污染而导致的NOx净化装置的劣化时，特定的运转状态标志FHL被设定为“1”，并且等于或短于例如三秒的间隔，供给到发动机的空气燃料混合物变化，使得其交替地比理论空燃比更浓和更丰富。当执行空燃比变更控制时，当NOx净化装置的温度TCAT超过劣化恢复温度STCAT2时，SOx去除标志FHLSOx被设定为“1”，并且在与劣化恢复时间TRSOx相当的时间内，空燃比保持比理论空燃比更浓。
