1. 21. Engine Thermal Management in Heavy Duty Vehicles

   Författare :Arne Andersson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Control Simulation; Heat Exchangers; Heat Transfer; Thermal Management; Turbomachinery;

   Sammanfattning : Future regulations on noise and exhaust emissions have a large impact on heavy duty engine installations. Cooled EGR is used for NOx abatement. Better sealed engine encapsulations are used to meet new noise regulations. Engine thermal management is therefore becoming an increasingly important discipline. LÄS MER

3. 22. Fuel-Efficient Heavy-Duty Vehicle Platoon Formation

   Författare :Kuo-Yun Liang; Karl Henrik Johansson; Jonas Mårtensson; Carlos Canudas-de-Wit; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : There is a need for intelligent freight transport solutions as the demand for road freight transport is continuously increasing while carbon footprint needs to be significantly reduced. Heavy-duty vehicle (HDV) platooning is one potential solution to partially mitigate the environmental impacts as well as to reduce fuel consumption, improve traffic safety, and increase traffic throughput on congested highways.

4. 23. DME and the Heavy Duty Diesel Engine

   Författare :Henrik Salsing; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; combustion; diesel engine; Dimethyl Ether; fuel injection system; DME;

   Sammanfattning : Increasing awareness of adverse anthropogenic environmental effects, such as the effectsof combusting fossil fuels on atmospheric carbon dioxide concentrations, and thatcombustion-related emissions from the transportation sector are going to approachsustainable levels in the near future has led to increased interest in fuels from renewablesources. These fuels offer possibilities to diversify the feedstocks that can be used forfuel production, as well as to reduce fossil carbon dioxide emissions, thereby reducingour dependence on a very limited range of sources.

7. 25. Development of a Novel Method for Lithium-Ion Battery Testing on Heavy-Duty Vehicles

   Författare :Pontus Svens; Mårten Behm; Göran Lindbergh; Per Alvfors; Anders Malmqvist; KTH; []
   Nyckelord :Lithium-ion battery; HEV; field testing; heavy-duty vehicles;

   Sammanfattning : Increasing demands for lower environmental impact from vehicles, including heavy-duty vehicles, have driven several vehicle manufacturers to consider adding hybrid electrical vehicles (HEV’s) to the product portfolio. Present research on batteries for HEV’s is mainly focused on lithium-ion battery chemistries, since lithium-ion batteries has the most promising technical potential compared to other types of batteries.
