EGR (Exhaust Gas Recirculation) är en teknik som används för att minska utsläppen av kväveoxider från förbränningsmotorer. Med EGR återcirkuleras delar av avgaserna till motorn vilket medför att sot och andra partiklar samt sura ämnen återförs. Därmed ställs det nya krav på …
… concept that utilizes a pilot diesel injection to ignite a homogenous natural gas/air mixture. Emissions and engine efficiency have been analyzed in an emission cycle called European Stationary Cycle (ESC) and the knock/pre-ignition problems with this type of engine have been …
A Biogas plant in SLU’s (Swedish University of Agricultural Sciences) management sustains to behave in con-nection with the new animal stables at Lövsta. There will primarily manure from stables that rot to biogas. The biogas plant will also have the capacity that rot others …
… The first part of the thesis deals with the effects of emissions of greenhouse gases in our atmosphere. There is a discussion about what counts as greenhouse gas. Interviews have been made with two growers of annual plants and one interview with a person who has worked hard to …
… University of Agricultural Sciences in Uppsala are studying greenhouse gas emissions fromcultivated peat soils. To measure carbon dioxide emissions from peat soils in the field the researchgroup are now using two portable carbon dioxide meters (Vaisala GMP343). For practical …
