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

    University essay from KTH/Maskinkonstruktion

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

    Abstract : 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. READ MORE

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

    University essay from Lunds universitet/Kemiteknik (CI)

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

    Abstract : 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. READ MORE

  6. 5. Analysis of Aircraft Emissions Based on Flight Trajectory : ATR 72-500 trajectory and emission study

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Gustav Forsberg; Carl-Michael Sundberg; [2022]
    Keywords : trajectory; emissions; Boeing Fuel Flow;

    Abstract : Emissions related to aviation have during the last decades become an important topic of discussion. Besides carbon dioxide ($CO_2$) which is the major pollutant from air travel, other gas emissions such as hydrocarbons ($HC$), nitrogen oxides ($NO_x$), carbon monoxide ($CO$) and sulfur oxides ($SO_x$) also need to be investigated.
