CREATING A RANKING OF DIAGNOSTIC PARAMETERS FOR THE DYNAMIC PROCESS OF A MARINE COMBUSTION ENGINE IN THE ASPECT OF MULTI-CRITERIA EVALUATIONS

Abstract

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. Presented in the paper 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 the fuel injection advancement. 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 sensitivity of a diagnostic parameter. Based on this method, a ranking of diagnostic parameters can be created, which divides the set of diagnostic transients into stimulators, destimulators and nominants. This normalization of the set seems to be helpful while making a diagnostic decision.
