2. 1. Experimental Studies of Advanced Ignition Systems for Lean Burn Natural Gas Engines

   Author : Jessica Dahlström; Förbränningsmotorer; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ignition system; spark energy; internal combustion engine; engine; spark ignition; natural gas;

   Abstract : One of the greatest challenges for the transport sector today is reducing its environmental impact. This applies especially to the emission aspects, much due to increasingly stringent emissions legislations. READ MORE

4. 2. Alkylate Petrol. Environmental Aspects of Volatile Hydrocarbon Emissions

   Author : Ulf Östermark; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; hydrocarbons; small engines; alkylate; alkenes; ethene; benzene; 3-butadiene; two-stroke engines; reformulated petrol; reformulated gasoline; 1;

   Abstract : All hydrocarbons emitted from production and use of petrol are hazardous to human health and the environment, but to a different extent for individual compounds. This thesis compares and characterizes C2-C8 hydrocarbons related to alkylate petrol and conventional petrol. READ MORE

5. 3. Control of Hybrid Electric Vehicles with Diesel Engines

   Author : Karin Jonasson; Industriell elektroteknik och automation; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reglerteknik; robotteknik; Automatiska system; simulation; hybrid vehicle; diesel engines; Automation; control engineering; robotics; Environmental technology; pollution control; Miljöteknik; kontroll av utsläpp;

   Abstract : This thesis is an approach to improve electric hybrid vehicles with respect to fuel consumption and to fulfil the future intended NOX emission regulations. It is based upon the conclusions made in the licentiate thesis Analysing Hybrid Drive System Topologies (Jonasson, 2002). READ MORE

6. 4. On Surface Topography of Cylinder Liners

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

   Abstract : 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.

7. 5. Particulate Flows in Aftertreatment Systems

   Author : Henrik Ström; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Modeling; Computational fluid dynamics; Exhaust gas aftertreatment; Particulate matter; Multiphase flow; Particulate flow;

   Abstract : Emissions from internal combustion engines contain many components that have a detrimental effect on the environment and on human health, such as nitrogen oxides (NOx) and particulate matter (PM). In addition, the final product of any combustion of fossil fuel - carbon dioxide (CO2) - contributes to global warming. READ MORE
