  4. 7. Injector Nozzle Hole Parameters and their Influence on Real DI Diesel Performance

    Author : Mikael Lindström; Hans- Erik Ångström; Öivind Andersson; KTH; []
    Keywords : Mechanical engineering; Maskinteknik;

    Abstract : A modern diesel engine is capable of running efficiently with low exhaust gas emissions over a wide operating range. This is thanks to techniques such as turbocharging, EGR, charge air cooling and an advanced fuel injection process. The fuel injection process is important for the combustion and emission formation in the diesel engine. READ MORE

  5. 8. Methods for Characterization of the Diesel Combustion and Emission Formation Processes

    Author : Mikael Lindström; Hans-Erik Ångström; Werner Hentschel; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; diesel engine emissions; SRA - Energy; SRA - Energi;

    Abstract : In this thesis various aspects of the diesel engine fuel injection, combustion and emission formation processes have been evaluated. Several types of evaluation tools and methods have been applied. Fuel spray momentum was used to characterize injection rate and hole-to-hole variations in fuel injectors. READ MORE

  6. 9. Heat Transfer Prediction of In Service Welding in a Forced Flow of Fluid

    Author : Per Lindström; Lars-Erik Svensson; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sjöfartsvetenskap; Maritime Science;

    Abstract : An algorithm for heat transfer prediction of in-service welding operations in a forcedflow of fluid is presented. The algorithm presented is derived from Rosenthal’s 3D heatflow equation and boundary layer approximations. READ MORE

  7. 10. Improved CWM platform for modelling welding procedures and their effects on structural behaviour

    Author : Per Lindström; Lars-Erik Svensson; Lennart Josefson; Hannu Hänninen; Högskolan Väst; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CWM; FEM; WELD; STRESS; EPFM; Manufacturing and materials engineering; Produktions- och materialteknik;

    Abstract : A welding procedure specification is the document describing how a weld joint should be constructed. Arc weld processes are characterized by transient thermal behavior, leading to rapid changes in material properties and dynamic interaction between weld and base material. READ MORE
