  1. 1. Development of CAD Models for Large Silencer Platforms Using Design Automation

    Master-uppsats, Linköpings universitet/Produktrealisering

    Författare :Mahim Kai; Balagangadar Thilakar Arumugam; [2023]
    Nyckelord :Design Automation; Silencer; CFD; Extraction;

    Sammanfattning : Scania is known as a front-runner in the development of power trains for heavy vehicles, marine, and general industrial applications. As the regulations on emissions for combustion engine vehicles are getting tougher with increasing awareness on sustainable solutions and reducing environmental impact, the goal at Scania is to develop combustion engines to achieve low-pollutant emissions whilst achieving higher efficiency.

  3. 2. Development of Elastic Mechanism for actuation of Valve

    Master-uppsats, KTH/Maskinkonstruktion

    Författare :Nidhi Menon; [2023]
    Nyckelord :Compliant mechanism; Engine; HGR valve; Heat gas recirculation; Eftergivlig mekanism; HGR-ventil; läckage; varmgasåtercirkulationsventilen;

    Sammanfattning : The HGR valve, or hot gas recirculation valve, is an essential component of modern internal combustion engines. Its main function is to reduce emissions of nitrous oxide (NOx), which is a harmful pollutant produced during combustion. LÄS MER

  4. 3. Förorenad mark till följd av byggnadsbränder - Spridning av PAH i jorden efter byggnadsbrand i Alnarp

    Master-uppsats, Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)

    Författare :Maria Gustavsson; [2023]
    Nyckelord :residential fire; contaminated soil; soil samples; Polycyclic aromatic hydrocarbons; petrogenic combustion; Earth and Environmental Sciences;

    Sammanfattning : Pollutant emissions to the environment caused by human activity is a worldwide problem. This can occur due to residential fires which are often connected to loss of human lifes and belongings, as well as environmental damage. Residential fires canlead to emissions of pollutants that can be released to the air, water and soil. LÄS MER

  5. 4. Modelling the full-scale N2O emissions from wastewater treatment plants for identifying mitigation strategies

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Naga Deepika Peddamudium; [2023]
    Nyckelord :Modelling; simulation; ASM2dISS; N2O production pathways; N2O emission factor; mitigation strategies; water and environmental engineering; Technology and Engineering;

    Sammanfattning : Nitrous oxide (N2O) emissions, which primarily originate from the biological nitrogen removal process, dominate the release of greenhouse gases (GHGs) in wastewater treatment plants (WWTPs). N2O production occurs through dynamic microbial pathways that have a significant impact on the environment compared with other GHG emissions. LÄS MER
