    • In an exhaust gas purification system for an internal combustion engine, a NOx selective reduction catalyst for reducing NOx with ammonia that is adsorbed on the NOx selective reduction catalyst is disposed in an exhaust passage of the engine. In the NOx selective reduction catalyst, ammonia in a first adsorption state that is adsorbed at a low temperature and ammonia in a second adsorption state that is adsorbed at a high temperature are present. Because ammonia, which has been in the first adsorption state and which is desorbed from the NOx selective reduction catalyst, tends to be discharged to the atmosphere, a control section that estimates an adsorption amount of ammonia in the first adsorption state is provided in the exhaust gas purification system for the internal combustion engine in order to control the adsorption amount of ammonia in the first adsorption state within a specified level.
    • 在内燃机的废气净化系统中,在发动机的排气通路内配置有用于将NOx吸附在NOx选择还原催化剂上的用于还原NOx的NOx选择还原催化剂。 在NOx选择还原催化剂中,存在吸附在低温下的第一吸附状态的氨和处于高温吸附的第二吸附状态的氨。 由于已经处于第一吸附状态并且从NOx选择还原催化剂解吸的氨倾向于排放到大气中,所以在排气中设置了估计第一吸附状态的氨的吸附量的控制部 用于内燃机的气体净化系统,以控制在第一吸附状态下的氨的吸附量在规定水平内。

    • An exhaust purification system of an internal combustion engine is provided with a first NOX selective reduction catalyst which is arranged inside of an engine exhaust passage and which selectively reduces NOX by feed of a reducing agent, a second NOX selective reduction catalyst which is arranged inside of the engine exhaust passage at the downstream side of the first NOX selective reduction catalyst and which selectively reduces NOX by feed of a reducing agent, and a reducing agent feed device which feeds a reducing agent to the first NOX selective reduction catalyst. The system estimates the amount of adsorption of the reducing agent which is adsorbed at the second NOX selective reduction catalyst and prevents the estimated amount of adsorption of the reducing agent from exceeding the allowable value by adjusting the amount of feed of reducing agent from the reducing agent feed device.
    • 内燃机的排气净化系统设置有第一NO x选择还原催化剂,其被布置在发动机排气通道内部,并且通过进料还原剂选择性地还原NO x;第二NOX选择还原催化剂,其布置在 在第一NO x选择还原催化剂的下游侧的发动机排气通道,还原剂的进料选择性地还原NO x;还原剂供给装置,其向第一NO x选择还原催化剂供给还原剂。 该系统估计吸附在第二NOX选择还原催化剂上的还原剂的吸附量,并通过调节还原剂的还原剂进料量来防止估计的还原剂吸附量超过允许值 进料装置
