1. Model Predictive Urea Dosing Control Strategy for Heavy-Duty Diesel Vehicles
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Stricter requirements on the reduction of Nitrogen Oxides (NOx) in the emissions of heavy-duty diesel vehicles drives development for more efficient aftertreatment systems. An ammonia covered catalyst is one of the most successful technologies in reducing NOx by converting it into the harmless byproducts water and nitrogen. READ MORE

2. Strengthening of non-composite bridges by Partial Composite Action
University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserAbstract : A common bridge type is the steel-concrete bridge where the concrete deck is built over steel girders. In many earlier designs the bridge type was often built as non-composite, which means that the concrete deck and the steel girder has no shear connection at the steel-concrete interface and therefore bend as individual components.

3. Liquid Natural Gas : A study of the environmental impact of LNG in comparison to diesel
University essay from Linnéuniversitetet/Sjöfartshögskolan (SJÖ)Abstract : Liquefied Natural Gases (LNG) has been an alternative fuel in the marine industry for several years, but lately, the amount of ships that have been powered by methane has increased a lot. Some of the reasons for this is because LNG does not contain any sulfur and releases less nitrogen oxides than traditional maritime fuels. READ MORE

4. Investigation of carbon capture technologies for Sävenäs waste-to-energy plant
University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserAbstract : Carbon capture technologies have the potential to decarbonize the emissions to air from the heat and power sector and contribute to the necessary greenhouse gas emission mitigation in order to meet the Paris Agreement requirements. The energy requirement and ability to retrofit carbon capture units are crucial to convert existing power plants into more environmental benign processes to meet the Swedish national goal of greenhouse gas neutrality at 2045.

5. Influence of nitrocarburization on the thermomechanical fatigue properties of ductile iron for exhaust components : Analysis and comparisons of TMF-properties
University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)Abstract : New stricter environmental legislation requires lower emissions and fuel consumption of automotive engines. Therefore the fuel efficiency must be increased but this leads to higher loads in the engine. As for the exhaust system it is affected by higher thermomechanical loads. READ MORE
