1. 1. On Surface Topography of Cylinder Liners

   Författare :Zlate Dimkovski; John Westberg; Högskolan i Halmstad; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cylinder liner; Surface Roughness; Characterisation; Honing; Wear; Blechmantel; Groove Parameters; Quality Control; Flow Simulation; Surface engineering; Ytbehandlingsteknik;

   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.

3. 2. Surfaces of Honed Cylinder Liners

   Författare :Zlate Dimkovski; B.-G. Rosén; Mohamed El-Mansori; Högskolan i Halmstad; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Honing; Characterisation; Blechmantel; Groove Parameters; Quality Control; Oil Consumption; Wear; Friction; Mixed Lubrication Simulation; Surface engineering; Ytbehandlingsteknik;

   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.

4. 3. 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

5. 4. 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
