  1. 6. Modeling of the Melting Process in an AdBlue Tank

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Emil Klinga; [2015]
    Nyckelord :AdBlue; Melting; moving boundary; modeling;

    Sammanfattning : This master thesis is covering the modeling of the melting process in a tank filled with AdBlue. Due to AdBlue freezing at temperatures below -11 degree there is a need to add heat to be able to secure dosing in all situations. LÄS MER

  2. 7. Investigating Urea Vaporization in a Controlled Environment Using Infrared Thermography

    Master-uppsats, KTH/Skolan för kemivetenskap (CHE)

    Författare :Henrik Grimler; [2015]
    Nyckelord :AdBlue; Infrared; Film; Evaporation; Deposits;

    Sammanfattning : As the emission legislation becomes more stringent, higher demands are put on the aftertreatment system in trucks. For dealing with nitrous oxides, AdBlue® (urea–water solution) is injected into the exhausts which evaporates and reduces nitrous oxides to nitrogen. LÄS MER

  3. 8. Investigation of urea deposit formation in vehicles with Selective Catalytic Reduction system

    H-uppsats, Chalmers tekniska högskola/Institutionen för tillämpad mekanik

    Författare :Lars Wallin; Tobias Holmström; [2014]
    Nyckelord :Urea deposits; urea injection; selective catalytic reduction; diesel exhaust aftertreatment; heat transfer model; AdBlue;

    Sammanfattning : In order to reduce NOX emissions from a diesel engine a urea-water solution called AdBlue is injected into the exhaust system. Risk of deposit formation is high due to unwanted side reactions that may occur during the decomposition of AdBlue during transient engine operation. LÄS MER

  4. 9. Modeling and Simulation of Urea Dosing System

    Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Författare :Zaki Ahmed; [2013]
    Nyckelord :Modeling; Simulation; Urea; Dosing;

    Sammanfattning : To protect our health and environment from pollution, among others regulatory agencies in the European Union (EU) and legislation from the U.S. Environmental Protection Agency (EPA) has required that pollutants produced by diesel engines - such as nitrogen oxides (NOx), hydrocarbons (HC) and particulate matter (PM) - be reduced.

  5. 10. Installation of Dual Reductant Tanks on a Truck Chassis

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Markos Saleeb; [2013]
    Nyckelord :Dual tanks; Electromagnetic sensor; Pneumatic pump; SCR; CATIA V5;

    Sammanfattning : Exhaust after treatment technology based on a reductant (urea) injection into the silencer, has been set up to be a very efficient tool to reduce the emission of the Engines especially NOx. The reductant is stored in a tank positioned on the truck chassis. LÄS MER
