  1. 1. Additives in a steam engine to decrease friction : Friction testing of solid lubricants in powder form

    Master-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Författare :Viktor Lange; [2023]
    Nyckelord :Tribology; friction; wear; steam; steam engine; ranotor; invencon; invencon AB; steel; contact mechanics; hexagonal boron nitride; molybdenum disulfide; tungsten disulfide; lubricants; solid lubricants; Tribologi; friktion; nötning; ånga; ångmotor; stål; kontaktmekanik; smörjning; smörjmedel; fasta smörjmedel;

    Sammanfattning : This thesis aims to investigate the coefficient of friction between steel on steel contacts with the addition of solid lubricants such as h-BN, WS2, MoS2 in powder form, in dry conditions and wet conditions. More specifically, the purpose is to enhance the sliding between the piston rings and cylinder block in a modern high temperature steam engine developed by RANOTOR. LÄS MER

  3. 2. Designregler för momentarm

    Uppsats för yrkesexamina på grundnivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Max Wallerman; [2023]
    Nyckelord :Maskinteknik; FEM;

    Sammanfattning : Bosch Rexroth is a company that manufactures radial piston hydraulic engines and accessories, commonly used in industries such as mining and marine applications. These engines generate significant torques during operation, often requiring the use of torque arms to handle the torque. LÄS MER

  4. 3. Optimal dead space in axial-type expander

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Martin Karman; [2022]
    Nyckelord :Dead space; Expander; Steam engine; Tolerance analysis; Axial-kolvmotor; Effektivitet; Expansionskammare; Kolv; Ångmotor;

    Sammanfattning : In this thesis a method for determining optimal dead space in an axial-type expander is developed. The axial-type expander in question is for use in a steam engine, a environmental friendly and fuel-agnostic alternative to the ICE-engine. LÄS MER

  5. 4. Converting an Automobile Engine to an Aircraft Engine

    Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Författare :Gabriel Kronberg; [2022]
    Nyckelord :Piston Engine; Tiny Friendly Giant; Aviation Emissions; Engine Cooling; GREET; BFFM2; Sustainable Aviation Fuel; Engine Conversion; Emission Estimation; Trade Study; Kolvmotor; Tiny Friendly Giant; Flygutsläpp; Motorkylning; GREET; BFFM2; Hållbart flygbränsle; Motorkonvertering; Utsläppsupskattning; Paramterstudie;

    Sammanfattning : This project evaluates the opportunity to convert a three-cylinder automobile piston engine (the Tiny Friendly Giant) to an aircraft engine from an environmental and practical point of view. The problem of increased emissions from aviation calls for technical and socioeconomic solutions, which is the reason why this report is written. LÄS MER

  7. 5. Development of a 3D Ring Dynamics Model For a Heavy-Duty Piston Ring-Pack

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Parthasri Akurati; Karan Kumar; [2021]
    Nyckelord :3D ring model; Flank wear; Oil consumption; Piston ring dynamics;

    Sammanfattning : With the increasing restrictions in emission legislations, the automotive industry aims to improve the efficiency of the lubricating system and to decrease fuel consumption. In the power cylinder unit (PCU), the piston rings are the major contributor to these consumptions. LÄS MER
