4. 3. 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.

5. 4. A Surface Engineering Approach to Reduction of Frictional Losses of Heavy Duty Diesel Engines

   Författare :Staffan Johansson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cylinder Liner; Tribometer; Wear; Diesel Engine; Lubrication; Design of Experiments; Rig testing; Friction; Piston Ring; Oil consumption;

   Sammanfattning : Reducing emissions is a top priority within heavy duty diesel engine development and research. The aim of the work is to decrease the fuel consumption by decreasing frictional losses of the Power Cylinder Unit.Full scale testing of engine components improvements is time-consuming and costly.

7. 5. Surface Engineering Approach to Frictional Optimization

   Författare :Staffan Johansson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Piston Ring; Lubrication; Rig testing; Tribometer; Design of Experiments; Cylinder Liner; Friction; Oil consumption; Diesel Engine; Wear;

   Sammanfattning : Reducing emissions is a top priority within heavy duty diesel engine development and research. The power cylinder system is a main contributor to emissions and accounts for about 50% of the total frictional losses found in the engine, so is important to optimize. LÄS MER
