  2. 16. Characterization of the Combustion of Light Alcohols in CI Engines : Performance, Combustion Characteristics and Emissions

    Author : Sam Shamun; Förbränningsmotorer; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Methanol; Ethanol; Oxygenated Fuel Blends; Compression Ignition Engine; Partially Premixed Combustion; Combustion Characteristics; Efficiency; Emissions; Particulate Matter; Metanol; Etanl; Oxygenerade Bränsleblandningar; Kompressionsantänd Motor; Partiellt Förblandad Förbränning; Förbränningsegenskaper; Verkningsgrad; Emissioner; Partiklar;

    Abstract : Alternative fuels for combustion engines are becoming increasingly popular as society is pushing to phase out fossil energy to reduce CO2 emissions. The compression ignition (CI) engine has a high overall efficiency which makes it a valuable option for the transport fleet, despite the well known NOx and soot pollutants it emits. READ MORE

  4. 17. Model-Based Control of Gasoline Partially Premixed Combustion

    Author : Gabriel Ingesson; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pressure-Sensor Feedback; Model Predictive Control; Model-Based Controller Design; Partially Premixed Combustion;

    Abstract : Partially Premixed Combustion (PPC) is an internal combustion engine concept that aims to yield low NOx and soot emission levels together with high engine efficiency. PPC belongs to the class of low temperature combustion concepts where the ignition delay is prolonged in order to promote the air-fuel-mixture homogeneity in the combustion chamber at the start of combustion.

  5. 18. Particulate Matter Emissions from Partially Premixed Combustion with Diesel, Gasoline and Ethanol

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

    Abstract : 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. READ MORE

  6. 19. Impact of Fuel Properties on Partially Premixed Combustion

    Author : Hadeel Solaka; Förbränningsmotorer; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PPC; Reference Fuels; Gasline; Diesel; Ignition Delay; Quadratic Regression Model;

    Abstract : Compression ignited engines generally have higher efficiency than spark ignition engines. However, the most common combustion concept in compression ignited engines, conventional diesel combustion, struggles with high levels of particulate matter and NOx emissions. READ MORE

  7. 20. The HCCI Engine – High Load Performance and Control Aspects
