  2. 1. Homogeneous Lean Combustion in Downsized Spark-Ignited Engines

    Author : Kristoffer Clasén; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy efficiency; lean combustion; emissons; transportation;

    Abstract : Emissions of greenhouse-gasses and noxious compounds from internal combustion engines propelling personal transportation vehicles is an imminent issue in the society. Therefore, it is vital to find means of reducing these emissions to decrease the impacts of transportation. READ MORE

  5. 3. 1-D simulation of turbocharged SI engines : focusing on a new gas exchange system and knock prediction

    Author : Christel Elmqvist-Möller; Hans-Erik Ångström; Daniel Håkansson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; spark ignited engines; 1-D flow simulation; knock; Divided Exhaust Period; turbocharged engines; Other engineering mechanics; Övrig teknisk mekanik;

    Abstract : This licentiate thesis concerns one dimensional flow simulation of turbocharged spark ignited engines. The objective has been to contribute to the improvement of turbocharged SI engines’ performance as well as 1 D simulation capabilities. Turbocharged engines suffer from poor gas exchange due to the high exhaust pressure created by the turbine. READ MORE

  6. 4. Empirical combustion modeling in SI engines

    Author : Fredrik Lindström; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; spark ignited engines; combustion modeling; knock; 1D simulation; Wiebe; divided exhaust period; Engineering mechanics; Teknisk mekanik;

    Abstract : This licentiate thesis concerns the modeling of spark ignition engine combustion for use in one dimensional simulation tools. Modeling of knock is of particular interest when modeling turbocharged engines since knock usually limits the possible engine output at high load. READ MORE
