Subject(s): Abstract: Projektet utgör en del, av totalt tre delar, i projektet D60 - Sextioprocentsdieseln. Det är således ett samarbetsprojekt innefattande tre delar; modellering av värmeöverföringsprocesser i motor (D60m), modellvalidering med motorprov (D60e), samt den del som beskrivs i denna ansökan, nämligen utveckling och tillämpning av laserdiagnostiska mättekniker (D60l). Projektets övergripande målsättning är att undersöka möjligheterna att väsentligt öka verkningsgraden hos förbränningsmotorn. Målsättningen är att uppnå 60% verkningsgrad.Abstract: The present application constitutes one part, out of totally three, of the project D60 – The 60% efficient diesel engine. Hence, the proposed project is a collaboration involving research in three different areas; heat transfer model development (D60m), model validation and tuning by engine tests (D60e), and the research covered in this application, i.e. development and application of laser-based diagnostics (D60l). The overall goal of this project is to study possibilities to significantly increase the fuel efficiency of the internal combustion engine. The ultimate goal is to reach 60% efficiency, i.e. 60% of the fuel energy content should be converted to mechanical work. In order to reach this goal all losses in the fuel conversion process must be taken into account and minimized. An important factor is heat losses to the walls in the combustion chamber. Hence, experimental data on thermal boundary layers and wall temperatures are imperative for validation of heat transfer models. Therefore, advanced laser diagnostics will be developed and applied in order to deliver such information; laser-induced fluorescence (LIF) for characterization of thermal boundary layers and laser-induced phosphorescence (LIP) for surface thermometry.
