  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. Evaluation of pretension losses in heated screw joint

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Joel Svensson; [2022]
    Nyckelord :screw joint; clamping force; thermal load;

    Sammanfattning : The heated flow within the silencers of heavy transport vehicles can easily reach temperatures of hundreds of degrees Celsius. The thermal loads can cause problems for certain components on a silencer. LÄS MER

  4. 3. Simulating flow-noise for after-treatment systems

    Master-uppsats, KTH/Teknisk mekanik

    Författare :Adam Sandström; [2020]
    Nyckelord :Flow-noise; CAA; DES; non-refelctive boundary conditions; stretched grid; Menter SST;

    Sammanfattning : Modern silencers for heavy vehicle applications are designed to cancel out the sound generated by the effects of combustion and propagation of exhaust gases through the engine after-treatment system. The complex geometry within the compact silencer give rise to self generated (or flow-) noise that contribute to the total sound power radiated at the exhaust outlet. LÄS MER

  5. 4. Water blow out phenomena inside a heavy truck silencer

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Rohit Suram Venkata Subramaniyam; [2020]
    Nyckelord :Water blow out in after treatment devices; Dew point strategy; Exhaust after treatment system; NOx sensors; Water formation in the exhaust; Vatten blåser in efter behandlingsanordningar; Daggpunktsstrategi; Avgas efter behandlingssystem; NOx-sensorer; Vattenbildning i avgaserna;

    Sammanfattning : NOx sensors have become salient components in the development of efficient exhaust after treatment system for heavy duty vehicles in the past few years. When the accumulated water inside the silencer splashes on to the NOx sensor, it can cause permanent cracks in the sensor. LÄS MER

  7. 5. Evaluation of parametric CAD models from a manufacturing perspective to aid simulation driven design

    Master-uppsats, Linköpings universitet/Maskinkonstruktion; Linköpings universitet/Industriell Produktion

    Författare :Nachiketh Satish Prabhu; Ranjan Tunga Sarapady; [2019]
    Nyckelord :Simulation Driven Design; Parameteric CAD models; CAD; DOE; MDO; InspireForm; Apriori; CATIA V5;

    Sammanfattning : Scania are known among to be the world’s leading supplier of transport solutions for heavy trucks and buses. Scania’s goal is to develop combustion engines that achieve low-pollutant emissions as well as lower carbon-footprint with higher efficiency. LÄS MER
