  1. 1. Oil consumption and Friction in a Piston Ring-Cylinder Liner assembly.-A multifunctional Surface Approach

    Författare :Cecilia Anderberg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cylinder liner surface; surface characterization; oil consumption; surface texture parameters;

    Sammanfattning : About a half of the frictional losses in an internal combustion engine come from the interactions between the piston assembly and cylinder liner surface. The tribological considerations in the contact between the piston ring and cylinder liner have attracted much attention over the past few decades. LÄS MER

  3. 2. Towards functional characterisation for cylinder liner surfaces

    Författare :Cecilia Anderberg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The demands on decreased environmental impact from vehicles force the automotive industry to develop engines with reduced engine oil and fuel consumption. Frictional losses in the piston ring cylinder liner system accounts for approximately 20 % of the total frictional losses within an engine. LÄS MER
