摘要： An exhaust gas purifier for an internal combustion engine which is capable of detecting the deterioration degree of an NOx catalyst making use of a time elapsed from the time when the air-fuel ratio of exhaust gas flowing into an NOx absorber catalyst is made rich to the time when the air-fuel ratio of exhaust gas flowing out from the NOx absorber catalyst becomes rich. When the time required for a change in the output level of an air-fuel ratio sensor is shorter than a predetermined time, the time required for the change in the output level of the air-fuel ratio sensor is lengthened by reducing the rich degree at the time of rich operation, thereby judging the deterioration degree of the NOx absorber catalyst with accuracy.

摘要： A cylinder identifying system for an internal combustion engine enables fuel injection and ignition controls for individual cylinders to be speedily performed upon starting of engine. A cylinder identifying means (10) operating on the basis of a crank angle signal (SGT) and a cam signal (SGC) includes a pulse signal number storage means (12) for dividing an ignition control period of each cylinder into plural subperiods for counting for storage signal numbers of specific pulses generated over plural subperiods, and a subperiod discriminating means (14) for determining discriminatively a sequential order of the plural subperiods on the basis of combinations of the numbers of the specific pulses generated during the plural subperiods. The combinations of the numbers of specific pulses generated during the plural subperiods differ one another correspondingly to the plural subperiods independently from the start points thereof. The cylinder identifying means (10) identifies the individual cylinders on the basis of results of determination made by the subperiod discriminating means (14) independently of positional relationships between the storage start points and the subperiods.
