2. 1. Engine Thermal Management in Heavy Duty Vehicles

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

   Abstract : 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. READ MORE

4. 2. Transient vibrations from dry clutch operation in heavy-duty truck powertrains : Modelling, simulation and validation

   Author : Jakob Sjöstrand; Leif Kari; Ines Lopez Arteaga; Per Erik Austrell; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dry clutch system; Engagement; Disengagement; Dry-friction; LuGre friction model; Heavy-truck powertrain; Teknisk mekanik; Engineering Mechanics;

   Abstract : For internal combustion engines used in heavy-duty vehicles, increased engine efficiency and consequently reduced CO2 emissions can be obtained if the engine speed can be kept within an optimal speed range. This requires swift and frequent gear shifts where the dry friction clutch is utilized. READ MORE

5. 3. Divided Exhaust Period on Heavy-Duty Diesel Engines

   Author : Stefan Gundmalm; Hans-Erik Ångström; Fredrik Ekström; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Due to growing concerns regarding global energy security and environmental sustainability it is becoming increasingly important to increase the energy efficiency of the transport sector. The internal combustion engine will probably continue to be the main propulsion system for road transportation for many years to come. READ MORE

6. 4. Gas-Diesel Dual-Fuel Combustion in a Heavy-Duty Engine

   Author : Zhiqin Jia; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Global efforts have been devoted to developing different kinds of alternative fuels in order to reduce the dependence on conventional petroleum fuels. Among these alternative fuels, the compressed natural gas (CNG) is a pop- ular choice because of its relatively clean combustion and global availability at attractive prices. READ MORE

7. 5. Methanol Diesel Dual Fuel Direct Injection in a HD-CI Engine

   Author : Michael Saccullo; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Alcohol Fuels; Heavy Duty Engine; Dual Fuel; Combustion;

   Abstract : Laws concerning emissions from heavy duty (HD) internal combustion engines are becoming increasingly stringent. New engine technologies are needed to satisfy these new requirements and to reduce fossil fuel dependency. READ MORE
