  1. 1. High Temperature Tribology of Exhaust Components in Alternative Fuel Engines

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Muhammad Hashir Zaheer; [2023]
    Nyckelord :High temperature tribology; Wear; Friction; Exhaust manifold; Lip seal ring; Wear resistant coatings; Inconel 718c; SiMo51 ductile cast iron; AlTiN; Tribaloy 400;

    Sammanfattning : Internal Combustion Engine (ICE) exhaust components are exposed to extreme operating temperatures. Thus, it is necessary that they are designed with materials that can sustain thermal and vibrational stresses. LÄS MER

  3. 2. Influence of nitrocarburization on the thermomechanical fatigue properties of ductile iron for exhaust components : Analysis and comparisons of TMF-properties

    Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Karl Larsson; [2019]
    Nyckelord :Thermo-mechanical fatigue; low cycle fatigue; thermal strain; ductile cast iron; nitrocarburizing;

    Sammanfattning : New stricter environmental legislation requires lower emissions and fuel consumption of automotive engines. Therefore the fuel efficiency must be increased but this leads to higher loads in the engine. As for the exhaust system it is affected by higher thermomechanical loads. LÄS MER

  4. 3. High temperature corrosion in exhaust application for heavy-duty trucks

    Master-uppsats, KTH/Materialvetenskap

    Författare :Alice Moya; [2019]
    Nyckelord :high temperature corrosion; austenitic steel; cast iron; cast steel; oxidation; exhaust gas; engine; heavy-duty trucks;

    Sammanfattning : Increasing awareness of environmental protection has made both governments and the industry aim for lowering carbon dioxide emissions. For the transport industry this means increasing engine efficiency, replacing fossil fuels with bio-based fuels or full electrification. LÄS MER

  5. 4. Influence of Nitrocarburization on Thermo-Mechanical Fatigue Properties : Material Characterization of Ductile Cast Iron for Exhaust Components

    Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Wännman Sofia; [2018]
    Nyckelord :Ductile cast iron; Nitrocarburizing; Thermo-mechanical fatigue;

    Sammanfattning : The large number of vehicles operating on the roads cause high emissions and consequently a negative effect on the environment. When developing and optimizing internal combustion engines, certain requirements must be considered, which are environmental regulations, reduced fuel consumption and increased specific power. LÄS MER
