  1. 1. Identifying risks of AdBlue spray on stainless steel surfaces

    University essay from KTH/Kemiteknik

    Author : Evelina Tvinne Flyg; [2021]
    Keywords : Urea; Stainless steel; SCR; Deposit; Corrosion; Urea; rostfritt stål; SCR; Avlagring; Korrosion;

    Abstract : Utsläppskontroll, reglerad av allt strängare lagstiftning, ställer höga krav på utvecklingen av noggranna efterbehandlingssystem för avgaser. När det gäller utsläpp från dieselmotorer utgör NOx-minskning en av de största utmaningarna. För tunga fordon tacklas denna utmaning ofta genom ett SCR-system. READ MORE

  3. 2. Freeze-drying of protein pharmaceuticalin vials with different character

    University essay from Uppsala universitet/Institutionen för farmaci

    Author : Julia Falk; [2019]
    Keywords : ;

    Abstract : Freeze-drying of protein pharmaceuticals is a procedure frequentlyused to obtain stability of the active pharmaceutical ingredientduring distribution and storage. It can be performed in pre-filledsyringes, with a lubricous coating of silicone on the inside, toenable the piston moving. READ MORE

  4. 3. A Method for Reducing Ash Volume in Wall-Flow Diesel Particulate Filters : Water Injection as a Service Tool to Improve Fuel Consumption and Particulate Filter Service Life

    University essay from Linköpings universitet/Maskinkonstruktion

    Author : John Allen; [2017]
    Keywords : ;

    Abstract : In order to meet today’s environmental standards, diesel vehicles must capture the soot and ash emitted from the engine in what is known as a diesel particulate filter (DPF). The continual ash loading of this filter and subsequent exhaust backpressure, increase in fuel consumption, etc. is seen as an unavoidable expense. READ MORE

  5. 4. Modeling of Fuel Dynamics in a Small Two-Stroke Engine Crankcase

    University essay from Linköpings universitet/Fordonssystem; Linköpings universitet/Tekniska fakulteten

    Author : Johan Andersson; Oscar Wyckman; [2015]
    Keywords : Modeling; Event based modeling; Two-stroke engines; Crankcase; Fuel dynamics; Wall wetting; Gas mixing;

    Abstract : For any crankcase scavenged two-stroke engine, the fuel dynamics is not easily predicted. This is due to the fact that the fuel has to pass the crankcase volume before it enters the combustion chamber. READ MORE

  6. 5. Characterization of flow regimes between supercritical carbon dioxide and water in microfluidics, comparing coated and mechanically modified channels.

    University essay from Uppsala universitet/Mikrosystemteknik

    Author : Niklas Rogeman; [2014]
    Keywords : ;

    Abstract : Water and supercritical carbon dioxide have different wetting angles to a glass surface, where water has a lower angle. In a microfluidic channel, the lower wetting angle draws the water to surround the supercritical carbon dioxide and the supercritical carbon dioxide therefore easily form droplets or segments if the flow rate is low.
