The change of some of the engine’s structural parameters affects the change of toxic compound emission in exhaust gases. It mainly applies to the damage sustained by the charge exchange system as well as the fuel system and the engine supercharging system. These changes are definitely higher during dynamic states and the related transient states. As such, it is possible to speak of a diverse sensitivity of the diagnostic parameters on the exact same excitations which come from the structure of the engine but are realized in other states of load. In the paper presented is the diagnostic model of an engine, based on the theory of multi-equation models, in which the diagnostic symptoms are the indices and characteristics of exhaust gas compound emissions. For the sake of this paper, the modal value of the structure parameters was assumed to be the change in the angle of advance of the fuel injection. The diagnostic model of the engine was supplemented with the results of research conducted on a station equipped with a single cylinder CI test engine. In previous works of the author, the information capacity index method (the Hellwig method) was suggested for the measurement of the sensitivity of a diagnostic parameter. Based on this method, a ranking of diagnostic parameters can be created, which divides the collection of diagnostic transients into stimulators, destimulators and nominants. This normalization of the collection seems to be helpful during making a diagnostic decision.
