  2. 1. Mitigating Knock in Heavy Duty Spark Ignition Engines : Experiments and simulations of diluted ethanol and methanol combustion

    Author : Senthil Krishnan Mahendar; Anders Christiansen Erlandsson; Christer Spiegelberg; James Szybist; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ethanol; Methanol; Dilution; Spark Ignition; Miller Timing; Machine Design; Maskinkonstruktion;

    Abstract : To effectively reduce fossil fuel dependence in the transport sector, an unprecedented increase in renewable fuel production is required. Short chain alcohols, such as ethanol and methanol, are well placed as they can be produced in a variety of renewable pathways from most carbon sources. READ MORE

    Abstract : The objective of this thesis was to find ways of improving part-load efficiency for a spark ignition engine by studying the effects of variable-valve actuation on fluid flow and combustion. The in-cylinder flow was measured with laser doppler velocimetry, LDV, and particle image velocimetry, PIV. READ MORE

  5. 3. Essays on Financial Technology and SME Finance : A Tale of Two Effects of the Global Financial Crisis: Financing SMEs and Innovative Financing

    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Corporate Finance; Entrepreneurial Finance; Global Financial Crisis; Financial Innovation; Small and Medium Enterprises; Industriell ekonomi och organisation; Industrial Economics and Management;

    Abstract : The financial crisis of 2008-2009 took place exactly half a century after the publication of the seminal Modigliani and Miller (M&M) theorem, often called the capital structure irrelevance principle. This timing is curious since the crisis has highlighted the significance of deviations from assumptions of this theorem, i.e. READ MORE
