IPC: F01N9/00
Filed: 1993-07-06
Abstract: PURPOSE:To carry out deterioration diagnosis of a catalyst not only at the time of high speed running but also intermediate speed running, low speed running, and an idling time. CONSTITUTION:Operating condition is estimated by an operating condition estimating unit 20, and a catalyst temperature is estimated by a catalyst temperature estimating unit 19. A catalyst deterioration barometer is calculated by a catalyst deterioration barometer calculating unit 18. When a judging barometer is set, judging barometer curve is set by a judging barometer setting unit 22 to store in a memory unit 23. When the judging barometer is not set, deterioration barometer curve is calculated by a comparison unit 21, the judging barometer curve memorized in the memory unit 23 is read out, and then it is compared with the calculated deterioration barometer curve. It is judged by a deterioration judging unit 24 whether the level of the deterioration barometer is smaller than that of the judging barometer. If the level of the deterioration barometer is larger than that of the judging barometer, deterioration of the catalyst is displayed by a some proper displaying unit.
