MODELLING OF TOXIC COMPOUNDS EMISSION IN MARINE DIESEL ENGINE DURING TRANSIENT STATES AT VARIABLE PRESSURE OF FUEL INJECTION
Abstract
Transient states are an important part of the spectrum of engine loads, especially the traction engines. In the case of marine diesel engines, transient states are of particular importance in reducing the analysis of motion units for special areas and maneuvering in port, the participation of transient states in the load spectrum significantly increases, also, the emission of toxic compounds from this period increases proportionally. The factors which determine the value of the emission are the forces shaping transient states and the technical condition of the engine itself. To describe the transient states, authors propose the use of multi-equation models, the presented material focuses on the analysis of changes in toxic compound concentrations during transients at varying pressures of the injector opening, which is a typical regulatory parameter that undergoes relatively frequent changes in the process of using the engine. This paper presents a description of transient states using multi-equation models, and the analysis of their relevance. It also presents a comparison of toxic compounds concentration at modified angles of fuel injection advance.
