摘要： An exhaust gas purification device for an internal combustion engine comprises, an exhaust passage including a catalyst for conveying exhaust gas discharged from the engine to the outside, and a bend formed by bending a portion of the exhaust passage directly upstream of the catalyst, the bend causing exhaust gas discharged from the engine to collide against a corner portion between an inlet end face of the catalyst and such portion of a wall of the exhaust passage that follows the outside of the bend, thereby increasing pressure at the corner portion, compared with the other portion of the inlet end face, and an additive injection valve fitted to the outside of the bend of the exhaust passage to inject an additive in such manner that the injected additive passes just above the corner portion and falls on the inlet end face of the catalytic converter.

摘要： A catalyst deterioration suppressing apparatus and method stops supply of fuel when an engine is decelerating, and prohibits the supply of fuel from being stopped when the catalyst temperature is equal to or higher than a predetermined temperature when the engine is decelerating. When the supply of fuel is prohibted from being stopped, the air-fuel ratio is prohibited from being feedback-controlled. As a result, it is possible to control the air-fuel ratio in a stable manner while suppressing deterioration of a catalyst.

摘要： In an exhaust gas purifying apparatus of an internal combustion engine, the temperature of occlusion-type NOx catalyst is increased to emit SOx when the temperature of occlusion-type NOx catalyst is not less than a set temperature. This prevents the deterioration of fuel consumption and enables the regeneration of a catalyst device by efficiently desorbing a sulfur component from the catalyst device. In this case, the temperature of the occlusion-type NOx catalyst is preferably set according to the frequency of the SOx desorption, and the temperature of the occlusion-type NOx catalyst can be increased by, for example, retarding an ignition timing.
摘要翻译： 另外，在内燃机的废气净化装置中，当吸留型NOx催化剂的温度为设定温度以上时，吸留型NOx催化剂的温度上升，发出SOx。 这防止了燃料消耗的劣化，并且通过有效地从催化剂装置解吸硫成分，能够使催化剂装置再生。 在这种情况下，阻挡型NOx催化剂的温度优选根据SOx解吸的频率来设定，并且可以通过例如延迟点火正时来提高闭塞型NOx催化剂的温度。

摘要： A control device of a lean-burn engine has an electronic control unit. Upon start of switching from stoichiometric driving to lean driving, the control unit (10) derives, from a map, a target pressure (P0) and a basic opening degree (D0) of an idling speed control valve, serving as an air bypass valve, based on the throttle opening degree (TPS) and the engine rotation speed (Ne) at the start of the switching. The control unit supplies driving pulses (N) of a number corresponding to the basic opening degree (D0) to a stepper motor (32) of the idling speed control valve. Then, the control unit supplies the stepper motor with driving pulses of a number corresponding to an opening degree correction amount (D1) which in turn corresponds to a deviation between the target intake pressure (P0) and an actual intake pressure (PB), to thereby suppress a change in the torque at the time of switching between the rich driving, including the stoichiometric driving, and the lean driving of the lean-burn engine.
