  1. 6. Enhancement of evaluation method of journal bearings’ performance in heavy-duty diesel engines

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Sateesh Nataraj; [2021]
    Keywords : Asperity contact pressure; elastohydrodynamic lubrication; friction; flow factors; run-in wear profile; Asperitetskontakttryck; elastohydrodynamik; friktion; flödesfaktorer; slitageprofil efter inkörning;

    Abstract : Journal bearings are being used in various locations of an internal combustion engine. They contribute to a large portion of total engine friction and lowering it means a significant contribution to CO2 reduction. READ MORE

  3. 7. Development of a Method to Prepare a Test Fluid with Soft Particles in Biodiesel Fuel Blends

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Vishal Jadwani; [2020]
    Keywords : Biodiesel; Heavy-Duty Trucks; Soft Particles; Fuel mixtures; Biodiesel; Tunga lastbilar; Mjuka partiklar; Bränsleblandningar;

    Abstract : Bilindustrin är en av de största bidragsgivarna till koldioxidutsläpp genom fordonsutsläppnär de används. För att göra transportsektorn mer hållbar EU-politik dikterar att inkludera enhögre andel förnybara energikällor i den totala energiförbrukningen och ett sätt att uppnå det äratt införliva biobränslen i de traditionella fossila bränslena.

  4. 8. Design of energy storage application for forest harvester

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Samuel Hedström; [2020]
    Keywords : Harvester; Komatsu forest; Hydraulics; Accumulator Energy storage; Hybrid;

    Abstract : Komatsu Forest AB in Umeå saw an opportunity to increase performance during fast varying loads, e.g., when starting to feed after the felling cut, that proved more difficult to reach with their new line of stage V forest harvesters. READ MORE

  5. 9. CFD Simulation of Urea Evaporation in STAR-CCM+

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Oscar Ottosson; [2019]
    Keywords : Urea; AdBlue; SCR; Solid Deposit; NOx; nitrogen oxides; CFD; speedup; spray simulation; UWS; diesel after-treatment; STAR-CCM ; AVL Fire; Scania; Sweden; NXPS; LiU; DOE; Urea; AdBlue; SCR; Klump; NOx; kvävedioxider CFD; uppsnabbning; spray simulering; UWS; efterbehandling av diesel-motor; STAR-CCM ; AVL Fire; Scania; Sverige; NXPS; LiU; DOE;

    Abstract : Diesel engines produce large amounts of nitrogen oxides (NOX) while running. Nitrogen oxides are highly toxic and also contribute towards the formation of tropospheric ozone. READ MORE

  6. 10. Physical modeling of a heavy-duty engine for test-cycle simulations in Modelica

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Peter Jonsson; [2018]
    Keywords : Technology and Engineering;

    Abstract : Engine development for reduced fuel consumption and for the ability to use alternative types of fuels is required as emissions and the limited access of petroleum are issues coupled to diesel engines. Experimental testing is in many cases insufficient and expensive in comparison with simulations for engine development. READ MORE
