  2. 21. Criteria for Machinability Evaluation of Compacted Graphite Iron Materials : Design and Production Planning Perspective on Cylinder Block Manufacturing

    Author : Anders Berglund; Cornel Mihai Nicolescu; Leonardo De Chiffre; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Metal Cutting; Compacted Graphite Iron CGI ; Machinability; Design of Experiments DoE ; Inverse Finite Element FE Modelling; Simulated Milling Method; SRA - Produktion; SRA - Production;

    Abstract : The Swedish truck industry is looking for new material solutions to achieve lighter engines with increased strength to meet customer demands and to fulfil the new regulations for more environmentally friendly trucks. This could be achieved by increasing the peak pressure in the cylinders. READ MORE

  4. 22. Combustion Sensing Methods - in Theory and Practice

    Author : Martin Larsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Internal combustion engines; HCCI; combustion measurements; measurement techniques; SI; signal processing; pressure sensors; ion current sensors;

    Abstract : Accurate, reliable sensors are essential parts of any control system, and there are increasing needs for feedback systems to monitor and control key parameters of automotive internal combustion engines, operating in various combustion modes and configurations, to reduce fuel consumption and engine-out emissions. Thus, there are strong motives for studying combustion sensors. READ MORE

  5. 23. Injection Strategies for Heavy Duty DI Diesel Engines

    Author : Tanja Rente; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; multiple injections; injection pressure; local heat transfer; diesel combustion; injection duration; orifice number; injection strategies;

    Abstract : Diesel engines enjoy widespread popularity in transportation and industrial systems. The reasons for this popularity are their simplicity, relatively low capital costs, durability and high fuel efficiency. READ MORE

  6. 24. Surface Engineering Approach to Frictional Optimization

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

    Abstract : 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. READ MORE

  7. 25. Nature-inspired passive flow control using various coatings and appendages

    Author : Ugis Lacis; Shervin Bagheri; Christophe Eloy; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flow control; passive appendage; surface coating; pressure drag; friction drag; Flödeskontroll; passiva bihang; ytbeläggning; tryckmotstånd; friktionsmotstånd;

    Abstract : There is a wide variety of tails, fins, scales, riblets and surface coatings, which are used by motile animals in nature. Since organisms currently living on earth have gone through millions of years of evolution, one can expect that their design is optimal for their tasks, including locomotion. READ MORE
