    Sammanfattning : The transportation sector is one of the main contributors to greenhouse gas CO2 and emission of toxic gas. In this sector, advanced technologies and innovations to increase engine efficiency is an important research topic. Low-Temperature Combustion (LTC) concepts are effective approaches for high-efficiency engines. LÄS MER

  3. 22. Gasoline Partially Premixed Combustion - An Advanced Internal Combustion Engine Concept Aimed to High Efficiency, Low Emissions and Low Acoustic Noise in the Whole Load Range

    Författare :Vittorio Manente; Förbränningsmotorer; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Environmental concerns such as global warming, the surge of crude oil prices and more stringent emission regulations are demanding the development of internal combustion engines that are highly efficient and low polluting. With classical internal combustion engine concepts such as diesel compression ignition and gasoline spark ignition engines, a trade-off exists between local and global emissions i. LÄS MER

    Sammanfattning : European emission legislation has in recent years put a strict limit on NOx emissionsfrom heavy-duty truck engines. EGR and selective catalytic reduction are the two mostcommon technologies applied in a modern heavy-duty diesel engine to fulfill the legislation. LÄS MER

  5. 24. Physical Modeling and Control of Low Temperature Combustion in Engines

    Författare :Anders Widd; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The topic of this thesis is model-based control of two combustion engine concepts, Homogeneous Charge Compression Ignition (HCCI) and Partially Premixed Combustion (PPC), using physics-based models. The studied combustion concepts hold promise of reducing the emission levels and fuel consumption of internal combustion engines. LÄS MER

  7. 25. Direct Numerical Simulations of Low Temperature Combustion in IC Engine Related Conditions

    Författare :Fan Zhang; Strömningsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis deals with direct numerical simulation (DNS) of low temperature combustion in internal combustion engine related conditions. In particular, HCCI (homogeneous charge compression ignition), SACI (spark assisted ho-mogeneous charge compression ignition) and PPC (partially premixed charge combustion) were investigated to gain deeper understanding on the details of the combustion process.
