Identification of indicators sensitivity of emissions as a diagnostic parameter during the dynamic process of marine diesel engine.

Abstract: The change of some parameters of an engine structure affects emission of harmful components in engine's exhaust. This applies first of all to damages in a charge exchange system as well as in a fuel system and an engine supercharging system. These changes are significantly greater during dynamic states and in the time transient processes. It is possible to talk about different sensitivities of emission factors understood here as diagnostic parameters for the same extortion from the structure of the engine but … Show more

“…This damage includes the charge exchange system, the fuel system, and the engine supercharging system. These changes are substantially greater during dynamic states and time-transient processes [15] and [21]. Generally, it can also be assumed that the increase in exhaust gas temperature decreases the maximum exhaust gas pressure, and the decrease in it causes an increase in the maximum exhaust gas pressure [1].…”

“…Relating to the air supply and turbocharger condition diagnosis, some studies assess the relationship between the cause and symptoms of all potential problems that may occur during the operation [14]. Other researchers took experiments on real marine diesel engines and proposed measurements on the sensitivity of signals and the characteristics of exhaust emission parameters [15] to [17]. Zadrag and Bogdanowicz [15] focus on the relationships between output and engine structural parameters, considering output parameters as symptoms of the engine's technical condition.…”
