6. System Simulation of Partially Premixed Combustion in Heavy-Duty Engines : Gas Exchange, Fuels and In-cylinder Analysis
Abstract : The concept of partially premixed combustion (PPC), applied to conventional diesel engines, has shown to yield high gross efficiencies and low emissions of oxides of nitrogen and soot. PPC emerged from the knowledge gained from homogeneous charge compression ignition (HCCI) research. READ MORE

7. Silicon carbide field-effect devices studied as gas sensors for exhaust gas monitoring
Abstract : Metal-insulator-silicon carbide (MIS) structures have been studied as gas sensors. We have investigated how the sensors detect gases, how fast they do that, and how they could be used for exhaust gas monitoring.We have prepared simple field-effect devices, MIS-capacitors and Schottky diodes, on silicon carbide with platinum gates.

8. Fundamental Mathematical Modeling of Gas Injection in AOD Converters with Emphasis on the Inlet
Abstract : The overall purpose of the present work has been to developa novel mathematical model of the gas injection in the AODconverter process, based on fundamental transport equations.The model development was divided into two major steps, wherethe first step involved modeling of gas injection through acylindrical nozzle at high gas flow rates (the nozzle model).

9. Renewable gas in a Swedish context
Abstract : In order to increase the use of sustainable energy in Sweden, it is necessary to substitute fossil energy carriers with renewable counterparts. Synthetic natural gas (SNG) produced from renewable resources via biomass gasification and methanation could replace a proportion of the natural gas used in Sweden. READ MORE
