  1. 1. Efficiency and Mixing Analysis of EGR-Systems for Diesel Engines

    Författare :Simon Reifarth; Hans-Erik Ångström; Nils Tillmark; Andreas Cronhjort; José Galindo; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; EGR; Exergy; mixing; pulsating flow; HP-EGR; LP-EGR; high-pressure EGR; low-pressure EGR;

    Sammanfattning : The reduction of fuel consumption and the reduction of toxic emissions are the main goals of research and development in the area of internal combustion engines. The use of exhaust gas recirculation (EGR) to come further in that direction is today an established method for diesel engines. LÄS MER

  3. 2. Characterization and Control of Multi-Cylinder Partially Premixed Combustion

    Författare :Magnus Lewander; Förbränningsmotorer; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Efficiency estimation; Closed-loop control; EGR; Diesel engine; Partially Premixed Combustion; Combustion control;

    Sammanfattning : In the last decade diesel combustion has developed in a new direction. Research has been carried out trying to prolong the ignition delay and enhance fuel/air premixing to avoid diffusion combustion as well as lowering the combustion temperature through use of EGR. One of these new combustion concepts is Partially Premixed Combustion (PPC). LÄS MER

  4. 3. Design of Thermoelectric Generators for Automotive EGR Applications

    Författare :Olle Högblom; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Contact resistances; Exhaust gas heat recovery; Thermoelectrics; CFD;

    Sammanfattning : Rising energy prices and greater environmental awareness along with stringent emissions legislation in the automotive industry make it possible to introduce techniques in the aftertreatment system that have previously been unprofitable. One such technique, studied in this work, is heat recovery in the exhaust gas recirculation (EGR) cooler using thermoelectric generators (TEG). LÄS MER
