  1. 21. 3D parameterized FEM modelling of a piston ring in a marine diesel engine : a simulation approch using FEM

    University essay from Institutionen för fysik

    Author : Jon Elfridsson; [2010]
    Keywords : piston ring; finite element method; FEM; solid mechanics; contact pressure; twist; temperature field; three-dimensional; kolvring; finita elementmetoden; FEM; hållfasthetslära; kontakttryck; twist; värmelast; tredimensionell;

    Abstract : The piston ring in a marine two-stroke diesel engine operates in demanding conditions, involving high temperatures and pressures. Its main purposes are to seal the combustion chamber of the engine, minimize the frictional contact against the cylinder liner and transfer heat from the piston. READ MORE

  3. 22. Undersökning av avgasemissioner till vatten från dieselinombordsmotorer i fritidsbåtar : En jämförande studie av olika bränslen

    University essay from Institutionen för geovetenskaper

    Author : Ninnie Östman; [2006]
    Keywords : diesel engine; combustion; emission; FT-diesel; RME; PAH; alkylated benzenes; GC MS; ecotoxicological test;

    Abstract : In this Masters Thesis emissions to water from diesel engines in pleasure boats when driven with alternative fuels have been investigated. Two alternative fuels, Fischer-Tropsch-diesel (FT-diesel) and a blend of FT-diesel and rapeseed methyl ester (RME) have been compared with diesel of Swedish environmental class 1 (diesel EC1).

  4. 23. Automatic Tuning of Control Parameters for Single Speed Engines

    University essay from KTH/Reglerteknik

    Author : Johan Olsson; [2004]
    Keywords : PID-control; GenSet; automatic tuning.; PID-reglering; GenSet; auto-tuning.;

    Abstract : In Scania’s single speed engines for industrial and marine use, the engine speed is controlled by a PI-controller. This controller is tuned independent of engine type and application. This brings certain disadvantages since the engines are used in a wide range of applications where the dynamics may differ. READ MORE
