    Sammanfattning : Internal combustion engines have been the most used engine design when it comes to vehicle propulsion and transportation. But as the number of vehicles increase, new problems arise as well. LÄS MER

  3. 17. Particulate Matter Emissions from Partially Premixed Combustion with Diesel, Gasoline and Ethanol

    Författare :Mengqin Shen; Förbränningsmotorer; []
    Nyckelord :PPC; PM emissions; Diesel; Gasoline; Ethanol; Particle size distribution;

    Sammanfattning : To achieve cleaner combustion and higher efficiency in compression ignition (CI) engines, many new combustion strategies have been developed. Among these new concepts, partially premixed combustion (PPC) attracts a lot of attention, because of its possibility to achieve simultaneously low soot and NOx. LÄS MER

  4. 18. The Low Load Limit of Gasoline Partially Premixed Combustion (PPC) - Experiments in a Light Duty Diesel Engine

    Författare :Patrick Borgqvist; Förbränningsmotorer; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The decreasing oil supply, more stringent pollutant legislations and strong focus on decreasing carbon dioxide emissions drives the research of more efficient and clean combustion engines. One such combustion engine concept is Homogeneous Charge Compression Ignition (HCCI) which potentially achieves high efficiency and low NOx and soot emissions. LÄS MER

    Sammanfattning : The internal combustion engine has played a significant role in a vast number of applications from small cars to giant tankers, setting people free from geographical barriers and heavy labor. However, it has also generated many tons of harmful emissions and CO2that damage to humans and the environment. LÄS MER

  7. 20. A numerical study of mixing phenomena and reaction front propagation in partially premixed combustion engines

    Författare :Christian Ibron; Strömningsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFD simulation; förbränning; antändning;

    Sammanfattning : This work treats the modelling of PPC engine combustion through 3D computational fluid dynamics. In order to develop a cost-effective CFD model for the design and performance analysis of PPC engines it is important to first understand the multiple modes of combustion in PPC engines, e.g. LÄS MER
