  1. 1. Partially Premixed Combustion with Methanol in a Heavy Duty Engine

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Gustav Kristersson; [2015]
    Nyckelord :PPC Methanol; Technology and Engineering;

    Sammanfattning : PPC is a new combustion concept that combines high efficiency with low emissions. This thesis is based on experiments conducted with a heavy duty PPC engine that was ran on neat methanol. A fuel that might be a candidate for future engine propulsion in large scale. LÄS MER

  3. 2. Virtual Sensors for Combustion Parameters Based on In-Cylinder Pressure

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Tobias Johansson; [2015]
    Nyckelord :CLCC; virtual sensors; combustion parameters; in-cylinder pressure; heat release; heat-release; heavy duty vehicle;

    Sammanfattning : Typically the combustion in engines are open-loop controlled. By using an in-cylinder pressure sensor it is possible to create virtual sensors for closed-loop combustion control (CLCC). With CLCC it is possible to counteract dynamic effects as component ageing, fuel type and cylinder variance. LÄS MER

  4. 3. Experimental comparison of DI and PFI in terms of emissions and efficiencyrunning Ethanol-85

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Daniel Ottosson; Konstantinos Zioris; [2014]
    Nyckelord :;

    Sammanfattning : It has in recent year become more and more important to find an alternative to fossil fuel in our vehicles due to the increasing fuel price and to reduce their negative impact on the environment. One alternative is already in widespread use around the world, namely ethanol. LÄS MER

  5. 4. Electron transport in CdTe/ZnO radial nanowire array solar cells

    Master-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Matematisk fysik

    Författare :Oscar Hallbäck; [2013]
    Nyckelord :Photovoltaics; nanowire; heterojunction; ZnO; CdTe; Physics and Astronomy;

    Sammanfattning : This project was conducted during the spring of 2013 at the IMEP-LAHC laboratory in Grenoble, as part of their research into the electrical and optical properties of ZnO/CdTe-based radial nanowire array solar cells. Simulations with different transport mechanisms and physical properties of the semiconductors were made and compared to experimentally acquired data. LÄS MER

  7. 5. Electronics in Support of Combustion Feedback in Heavy-Duty Diesel Engines : An Investigation Using an FPGA-Based Approach

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Jonian Grazhdani; [2011]
    Nyckelord :;

    Sammanfattning :           Closed-loop controlled combustion is a promising technique to improve the overall performance of internal combustion engines and Diesel engines in particular. In order for this technique to be implemented some form of feedback from the combustion process is required. LÄS MER
