  1. 1. Particulate Emissions Associated with Diesel Engine Oil Consumption

    Detta är en avhandling från Stockholm : KTH

    Författare :Petter Tornehed; KTH.; [2010]
    Nyckelord :Lubrication oil; Particulate emission; Particulate matter PM ; Oil consumption; Diesel engine; TECHNOLOGY Other technology Mechanical engineering; TEKNIKVETENSKAP Övriga teknikvetenskaper Maskinteknik;

    Sammanfattning : Particulate emissions from diesel engines have been a key issue for diesel engine developers in recent decades. Their work has succeeded in reducing the exhaust particles from the combustion of fuel, which has led to increasing interest in the contribution of particulates from lubrication oil. LÄS MER

  3. 3. Oil-related Particle Emissions from Diesel Engines

    Detta är en avhandling från Stockholm : KTH

    Författare :Petter Johansson; KTH.; [2008]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Diesel engine; Particle emissions; Particulate matter; PM; Lubrication oil; Inter-ring pressure; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : In recent decades much effort has gone into reducing particle emissions in the exhaust gases of heavy-duty diesel engines. Engine development has now reached the stage where it is worth to put heavy focus on the contribution of lubricating oil to particulate emissions in order to further reduce these emissions. LÄS MER

  4. 4. Properties of oil and refrigerant mixtures lubrication of ball bearings in refrigeration compressors

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Roger Tuomas; Luleå tekniska universitet.; [2006]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine Elements; Maskinelement;

    Sammanfattning : A refrigeration compressor contains highly loaded mechanical contacts that have to be lubricated. The lubricant used in refrigeration compressors consists of an oil and refrigerant mixture, and the refrigerant concentration can be up to 40 wt%. LÄS MER

  5. 5. A Surface Engineering Approach to Reduction of Frictional Losses of Heavy Duty Diesel Engines

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Staffan Johansson; [2012]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cylinder Liner; Tribometer; Wear; Diesel Engine; Lubrication; Design of Experiments; Rig testing; Friction; Piston Ring; Oil consumption;

    Sammanfattning : Reducing emissions is a top priority within heavy duty diesel engine development and research. The aim of the work is to decrease the fuel consumption by decreasing frictional losses of the Power Cylinder Unit.Full scale testing of engine components improvements is time-consuming and costly.
