  1. 16. ESC-analys och studering av knack på en "Diesel Dual Fuel"-motor

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Robert Broman; Karl Rosenlind; [2009]
    Nyckelord :;

    Sammanfattning : A one-cylinder research engine has been used for studies with a Diesel Dual Fuel concept (DDF). DDF is a concept that utilizes a pilot diesel injection to ignite a homogenous natural gas/air mixture. LÄS MER

  3. 17. Diesel Dubbelbränsle Teknologi

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Emil Renman; [2008]
    Nyckelord :;

    Sammanfattning : The work covered in this report includes a literature study of the diesel dual fuel technology (hereinafter referred to as DDF). The literature study covers earlier work that has been done regarding the use of compressed natural gas (CNG) and diesel in a DDF system. LÄS MER

  4. 18. Evaluation of a statistical method to use prior information in the estimation of combustion parameters

    Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

    Författare :Patrick Rundin; [2006]
    Nyckelord :bayesian estimation; ion current; air fuel ratio; peak pressure location; SI engine control;

    Sammanfattning : Ion current sensing, where information about the combustion process in an SI-engine is gained by applying a voltage over the spark gap, is currently used to detect and avoid knock and misfire. Several researchers have pointed out that information on peak pressure location and air/fuel ratio can be gained from the ion current and have suggested several ways to estimate these parameters.
