ABSTRACT:
In a diagnostic system for an exhaust gas purifying apparatus in an internal combustion engine, such as a diagnostic system suitable for evaluating the exhaust gas purifying performance of a specific component, as an exhaust gas component concentration corresponding to an operating condition of the engine or an operating condition of the catalyst is detected using an exhaust gas component system, and the evaluation and diagnosis of the exhaust gas purifying apparatus are conducted on the basis of the thus-detected value directly or after subjecting it to an integral processing. With such a diagnostic system, it is not necessary to dispose a sensor upstream of the catalyst in the exhaust gas purifying apparatus, for diagnosis of the catalyst, thus permitting the system to be less expensive, highly durable and afford a high diagnostic accuracy according to operating conditions.
