16. Particulate Emissions Associated with Diesel Engine Oil Consumption
Abstract : Particulate emissions from diesel engines have been a key issue for diesel engine developers in recent decades. Their work has succeeded in reducing the exhaust particles from the combustion of fuel, which has led to increasing interest in the contribution of particulates from lubrication oil. READ MORE

17. A systematic approach for major renovation of residential buildings
Abstract : In Sweden, buildings are responsible for about 40 % of total energy use and about 10 % of total CO2 emissions Today more than 60 % of existing Swedish residential buildings are over 40 years old and are in need of major renovation. In addition, 15 % of all multi-family buildings and 27 % of all single-family houses were built before 1945. READ MORE

18. Particles and unregulated emissions from CI engines subjected to emission control
Abstract : Compression ignited (CI) engines, commonly known as diesel engines, are widely used power sources with complex emissions used in on-road and nonroad applications. To find out the impact of diesel exhaust emissions on health and the environment, both regulated and unregulated exhaust gas properties have to be evaluated. READ MORE

19. Reduction of the N2O Emission from Fluidized Bed Combustion by Afterburning
Abstract : A method for reducing N2O emissions from fluidized bed combustion is presented and investigated. In contrast to flame combustion, fluidized bed combustion generates significant amounts of nitrous oxide (N2O) which are emitted to the atmosphere. READ MORE

20. Methods for Characterization of the Diesel Combustion and Emission Formation Processes
Abstract : In this thesis various aspects of the diesel engine fuel injection, combustion and emission formation processes have been evaluated. Several types of evaluation tools and methods have been applied. Fuel spray momentum was used to characterize injection rate and hole-to-hole variations in fuel injectors. READ MORE
