    Sammanfattning : Access to clean and affordable energy is one of the cornerstones of the world's society. Since the introduction of the internal combustion engine, diesel engines have become widely used for transportation in the commercial sector. LÄS MER

  3. 12. Discribing the Auto-Ignition Quality of Fuels in HCCI Engines

    Författare :Per Risberg; David E. Foster; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Auto-Ignition Quality; RON; MON; Cetane Number; HCCI; CAI and Fuels; Other engineering mechanics; Övrig teknisk mekanik;

    Sammanfattning : The Homogeneous Charge Compression Ignition (HCCI) engine is a promising engine concept that emits low concentrations of NOx and particulates and still has a high efficiency. Since the charge is auto-ignited, the auto-ignition quality of the fuel is of major importance. LÄS MER

    Sammanfattning : 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. LÄS MER
