    • In an exhaust gas purification apparatus for an internal combustion engine (1) equipped with independent exhaust passages (2a, 2b) provided one for each cylinder group (1a, 1b) with a catalyst (3a, 3b) having a NOx trapping ability being arranged in each exhaust passage, the present invention is intended to provide a technique that can independently control the flow rates of exhaust gases flowing into the respective catalysts. To this end, the exhaust gas purification apparatus according to the present invention provides a communication passage (4) connecting mutually portions of said exhaust passages (2a, 2b) at upstream of said catalysts (3a, 3b), an upstream side switching valve (5) openning and closing said upstream side communication passage (4), a plurality of flow rate regulation valves (6a, 6b) being arranged at downstream of connecting portions of said exhaust passages with said upstream side communication passage, respectively, and a control section (9) controlling said upstream side switching valve (5) and said respective flow rate regulation valves (6a, 6b) in accordance with the states of said respective catalysts (3a, 3b). When the NOx trapping ability of one of the plurality of catalysts (3a, 3b) is regenerated, the control section (9) opens the upstream side switching valve (5), fully closes one flow rate regulation valve (6a, 6b) in one of the exhaust passages (2a, 2b) in which the one catalyst (3a, 3b) is arranged, and operates a reducing agent addition valve (7a, 7b) in such a manner that the reducing agent arrives at the one catalyst (3a, 3b) when the actual degree of opening of the one flow rate regulation valve (6a, 6b) becomes fully closed.
    • 在具有独立的排气通路(2a,2b)的内燃机(1)的排气净化装置中,每个气缸组(1a,1b)设有一个具有催化剂(3a,3b)的排气通道, 在每个排气通道中布置有NOx捕集能力,本发明旨在提供一种可以独立地控制流入各个催化剂的排气流量的技术。 为此,根据本发明的废气净化装置提供一种连通通路(4),其在所述催化剂(3a,3b)的上游处相互连接所述排气通路(2a,2b)的一部分, 侧开关阀(5)打开和关闭所述上游侧连通通道(4),多个流量调节阀(6a,6b)布置在所述排气通道与所述上游侧连通通道的连接部分的下游, 以及根据所述各个催化剂(3a,3b)的状态控制所述上游侧切换阀(5)和所述各流量调节阀(6a,6b)的控制部(9)。 当多个催化剂(3a,3b)中的一个催化剂(3a,3b)的NOx捕集能力再生时,控制部(9)打开上游侧切换阀(5),将一个流量调节阀(6a, b)在其中布置有一个催化剂(3a,3b)的排气通道(2a,2b)中的一个中,并且以这样的方式操作还原剂添加阀(7a,7b) 当一个流量调节阀(6a,6b)的实际开度达到完全关闭时,还原剂到达一个催化剂(3a,3b)。

    • An intake electromagnetic driving valve and an exhaust electromagnetic driving valve are provided which use electromagnetic force to drive an intake valve and an exhaust valve, respectively. In step 102, the ratio between the number of combustion execution cycles and the number of combustion halts is set to obtain a desired target output value. Output control patterns that each consist of combustion execution timing equivalent to the required number of combustion execution cycles, and combustion halt timing equivalent to the required number of combustion halts are set in step 106, 114. In steps 108 to 112, or 118 to 122, in accordance with the output control patterns, whether combustion is to be executed is set with respect to the explosion timing that arrives in each cylinder in order.
    • 提供了一种使用电磁力分别驱动进气门和排气阀的进气电磁驱动阀和排气电磁驱动阀。 在步骤102中,设定燃烧执行循环次数与燃烧停止次数之间的比例,以获得期望的目标输出值。 在步骤106,114中,设置各自包括与所需燃烧执行周期数相等的燃烧执行定时的输出控制模式,以及等同于所需燃烧次数的燃烧停止定时。 在步骤108至112或118至122中,根据输出控制模式,是否相对于按顺序到达每个气缸的爆炸定时来设定是否执行燃烧。
