    Sammanfattning : This thesis investigates the use of cylinder pressure measurements for estimation of the in-cylinder air/fuel ratio in a spark ignited internal combustion engine. An estimation model which uses the net heat release profile for estimating the cylinder air/fuel ratio of a spark ignition engine is developed. LÄS MER

  3. 3. On Surface Topography of Cylinder Liners

    Detta är en avhandling från Göteborg : Chalmers University of Technology

    Författare :Zlate Dimkovski; Högskolan i Halmstad.; [2008]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Materials science Surface engineering; TEKNIKVETENSKAP Teknisk materialvetenskap Ytbehandlingsteknik; Cylinder liner; Surface Roughness; Characterisation; Honing; Wear; Blechmantel; Groove Parameters; Quality Control; Flow Simulation;

    Sammanfattning : The frictional losses, oil consumption and emissions in internal combustion engines are in great extent controlled by the cylinder liner surface topography. This emphasises the importance of: investigating the liner’s topography by objectively characterising it, investigating its effects on the tribological function to gain a better understanding and improving its manufacturing.

  4. 4. Surfaces of Honed Cylinder Liners

    Detta är en avhandling från Göteborg : Chalmers University of Technology

    Författare :Zlate Dimkovski; Högskolan i Halmstad.; [2011]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Materials science Surface engineering; TEKNIKVETENSKAP Teknisk materialvetenskap Ytbehandlingsteknik; Honing; Characterisation; Blechmantel; Groove Parameters; Quality Control; Oil Consumption; Wear; Friction; Mixed Lubrication Simulation;

    Sammanfattning : Cylinder liner surfaces are often on the agenda of engine developers because of their large influence on the frictional losses, oil consumption and emissions of internal combustion engines. Improving the liner function involves not only manufacturing new surfaces and checking their function but also characterising them as a necessary intermediate step for better understanding of the changes made.
