  1. 1. The Performance of a Multi Cylinder HCCI Engine using Variable Compression Ratio and Fast Thermal Management

    Author : Jari Hyvönen; Förbränningsmotorer; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Motorer; framdrivningssystem; Variable Compression Ratio; Homogeneous Charge Compression Ignition VCR; termodynamik; Motors and propulsion systems; Termisk teknik; applied thermodynamics; Thermal engineering; Cylinder-to-cylinder; Turbocharging; Multi cylinder; Cylinder balancing; Thermal Management; HCCI;

    Abstract : The prime mover in the world today is the Internal Combustion (IC) engine. The development and improvement of the internal combustion engines since Nicolaus August Otto and Rudolf Diesel has continued until today and will continue long into the future. No major competitor to the IC engine has yet emerged. READ MORE

  2. 2. On the Computation of Turbulent Mixing Processes with Application to EGR in IC-engines

    Author : Alexander Sakowitz; Laszlo Fuchs; Michel Cervantes; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Turbulent Mixing; Large Eddy Simulations; IC-engines; T-junction;

    Abstract : This thesis deals with turbulent mixing processes occuring in internal combustion engines, when applying exhaust gas recirculation (EGR). EGR is a very efficient way to reduce emissions of nitrogen oxides (NOx) in internal combustion engines. READ MORE

  3. 3. Reduced models for flows in IC-engines

    Author : Niklas Winkler; Hans-Erik Ångström; Angelo Onorati; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The finite response time of the turbocharger is the most notable effect of transient operation on a turbocharged diesel engine. To fulfill future emission requirements, high amounts of transient EGR will be required even though after-treatment devices are being used. READ MORE
