摘要： Inside of a combustion chamber, ammonia is made to burn well. Inside of the combustion chamber 5, in addition to ammonia, reformed gas which is reformed inside of the reformer 20 is fed. When the reforming ability of the reformer 20 is a predetermined reforming ability or less, the ammonia ratio is made to increase over the ammonia ratio after completion of warmup which is preset according to the operating state of the engine, and secondary air is fed from the secondary air feed device 37 into the engine exhaust passage upstream of the exhaust purification catalyst 19.

摘要： An air-fuel ratio control apparatus for an internal combustion engine of the present invention determines whether or not a lean request has occurred, based on a comparison between a value correlating with an output value of the downstream air-fuel ratio sensor 56 disposed downstream of the catalyst 43 (downstream air-fuel ratio sensor output correlating value) and a predetermined lean request determining value, and determines whether or not a rich request has occurred, based on a comparison between the downstream air-fuel ratio sensor output correlating value and a predetermined rich request determining value. Further, the air-fuel ratio control apparatus calculates a total amount of oxygen (released oxygen amount) released from the catalyst in the rich request occurring period, and calculates an integrated value (present stored oxygen amount) of oxygen stored in the catalyst after a start of the lean request occurring period which follows the rich request occurring period. The apparatus changes the rich request determining value in such a manner that a point in time at which it is determined that the rich request has occurred comes much earlier as the present stored oxygen amount comes closer to the released oxygen amount.

摘要： An air-fuel ratio control apparatus for an internal combustion engine according to an embodiment of the invention (the present control apparatus) sets a target air-fuel ratio to a target rich air-fuel ratio when it is determined on the basis of the output value Voxs of a downstream air-fuel ratio sensor 67 that the oxygen adsorption amount of a catalyst 43 tends to be excessive, and sets the target air-fuel ratio to a target lean air-fuel ratio when it is determined on the basis of the output value Voxs that the oxygen adsorption amount of the catalyst 43 tends to be insufficient. Further, the present control apparatus determines whether or not an operation state in which a large amount of nitrogen oxide flows into the catalyst 43 is reached on the basis of "whether a predetermined condition is fulfilled", and makes the target rich air-fuel ratio obtained when the predetermined condition is fulfilled less than the target rich air-fuel ratio obtained when the predetermined condition is not fulfilled. As a result, the concentration of a reducing agent inside the catalyst 43 can be increased before a large amount of NOx flows into the catalyst 43. Therefore, when a large amount of NOx flows into the catalyst 43, most of the NOx can be eliminated.
摘要翻译：根据本发明实施例（本控制装置）的用于内燃机的空燃比控制装置在基于输出确定的情况下将目标空燃比设定为目标浓空燃比当基于该值确定催化剂43的氧吸附量趋于过度时，下游空燃比传感器67的值Voxs被设定为目标空燃比，并且将目标空燃比设定为目标稀空燃比输出值Voxs表明催化剂43的氧吸附量趋于不足。此外，本控制装置基于“是否满足预定条件”来判定是否达到大量氮氧化物流入催化剂43的操作状态，并且使目标浓空燃比当所述预定条件满足时，所述预定条件不满足所述预定条件时获得的所述目标浓空燃比。结果，在大量的NOx流入催化剂43之前，催化剂43内的还原剂的浓度可以增加。因此，当大量的NOx流入催化剂43时，大部分NOx可以被消除。

摘要： A first fuel of ammonia and a second fuel which is easier to burn than ammonia are used as fuels. An ammonia ratio is usually set to a reference ammonia ratio which is determined in advance in accordance with an operating state of an engine. At the time when feed of the fuel is restarted after suspension of feed of the fuel at the time of deceleration, the ammonia ratio is temporarily made lower than the reference ammonia ratio in accordance with the operating state of the engine.
