  1. 11. ɸ‑sensitivity : A step forward in future fuels evaluation

    Författare :Nika Alemahdi; Förbränningsmotorer; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Equivalence ratio; ɸ‑sensitivity; Cooperative Fuel Research engine; Method development; Biofuels.;

    Sammanfattning : Internal combustion engine is a developed and established technology whichcontributes largely to the transportation of goods and people. In one hand, theburning of fossil fuels is the main reason for the combustion engines to beconsidered unsustainable while on the other hand, the combustion behaviour ofrenewable fuels is not fully understood yet.

    Sammanfattning : Development and application of some laser techniques for the study of engine combustion are presented. The investigations mainly cover two aspects: fuel dynamics and formation of NO. LÄS MER

  4. 13. Processes in Optical Diesel Engines - Emissions Formation and Heat Release

    Författare :Ulf Aronsson; Förbränningsmotorer; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Diesel Engines; Optical Engines; Heat Release; Combustion; Emissions Formation; Mechanical Deformation;

    Sammanfattning : This project deals with questions related to generic diesel combustion research and optically accessible engines are used to study the combustion process. Images of the combustion are analyzed together with in-cylinder pressure and exhaust gas emission measurements. LÄS MER

  5. 14. Detailed Soot Modelling in Laminar and Turbulent Reacting Flows

    Författare :Michael Balthasar; Förbränningsmotorer; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; soot; turbulent; flames; engines; turbines; carbon black; ionization; laminar; Physics; Fysik; Fysicumarkivet A:2000:Balthasar;

    Sammanfattning : In the present work a detailed kinetic soot model is applied to study the formation and oxidation of soot particles in laminar premixed and turbulent non-premixed flames. The soot model used in this study is based on a detailed description of the chemical and physical processes involved in the formation of soot. LÄS MER

  7. 15. High Octane Number Fuels in Advanced Combustion Modes for Sustainable Transportation

    Författare :Amir Bin Aziz; Förbränningsmotorer; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Octane number; Low temperature combustion LTC ; Ignition delay; Methanol; HCCI; PPC; Multiple injection strategy; φ-stratification;

    Sammanfattning : The research community recently proposed a low-temperature combustion (LTC) concept that can simultaneously reduce Nitrogen Oxides (NOx) and soot emissions while maintaining high engine efficiency. Given that diesel fuel is prone to preignition with early injection, gasoline-like fuel with high octane number is utilised to provide sufficient ignition delay and extend the load range. LÄS MER
