  1. 1. Conceptual design of hydraulic systems for automotive engine applications : simulation, optimisation and testing

    Författare :Jochen Pohl; Nicola Nervegna; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : The main contribution of this thesis lies in the area of systems design, and especially of such systems that involve several engineering domains, so-called multidomain or heterogeneous systems. The design of these systems is concerned with a need for efficient tools, especially in the early conceptual phase of the development process. LÄS MER

  3. 2. On Alternative Fuels for Internal Combustion Engines : A study of biodiesel, gaseous methane and methanol

    Författare :Ludvig Adlercreutz; Andreas Cronhjort; Ola Stenlåås; Magnus Sjöberg; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gaseous methane combustion; spark ignition; single cylinder research engine; particle number; particle emissions; oil ash content; CO2; Green House Gases; engine testing; engine development; emissions; combustion chamber design; injector fouling; environmental impact; road transportation; Machine Design; Maskinkonstruktion;

    Sammanfattning :  This thesis covers some of the environmental impacts of internalcombustion engines running on alternative fuels. The focus of thestudies conveyed is the reduction of greenhouse gases and particleemissions, as these two factors are of great importance for the pathsthat road transportation is facing. LÄS MER

  4. 3. Acoustic modelling and testing of advanced exhaust system components for automotive engines

    Författare :Sabry Allam; Hand Bodén; Antonio Torregrosa; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Theoretical physics; acoustic modelling; testing; two-port; diesel particulate filter; after treatment device; Teoretisk fysik; Physics; Fysik;

    Sammanfattning : The increased use of the diesel engine in the passenger car, truck and bus market is due to high efficiency and lower fuel costs. This growing market share has brought with it several environmental issues for instance soot particle emission. LÄS MER

  5. 4. Wear resistant low friction coatings for engine components

    Författare :Per Lindholm; Sören Andersson; Rickard Larker; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering materials; cam; roller follower; carbon coating; engine test; finite element method; Konstruktionsmaterial; Construction materials; Konstruktionsmaterial;

    Sammanfattning : Engine development today is driven by cost, performance and government regulations. Customers want cars and trucks to consume less fuel, last longer, pollute less and be safer. Several of the requirements have tribological associations. For example, product longevity can be improved by lowering friction and using more wear-resistant components. LÄS MER

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

    Författare :Staffan Johansson; Chalmers tekniska högskola; []
    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.
