  1. 1. Discribing the Auto-Ignition Quality of Fuels in HCCI Engines

    University dissertation from Stockholm : KTH

    Author : Per Risberg; KTH.; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Auto-Ignition Quality; RON; MON; Cetane Number; HCCI; CAI and Fuels; TECHNOLOGY Engineering mechanics Other engineering mechanics; TEKNIKVETENSKAP Teknisk mekanik Övrig teknisk mekanik;

    Abstract : The Homogeneous Charge Compression Ignition (HCCI) engine is a promising engine concept that emits low concentrations of NOx and particulates and still has a high efficiency. Since the charge is auto-ignited, the auto-ignition quality of the fuel is of major importance. READ MORE

  2. 2. Development of ring-opening catalysts for diesel quality improvement

    University dissertation from Stockholm : Kemiteknik

    Author : Ulf Nylén; KTH.; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ring opening; naphthenes; cetane number improvement; indan; light cycle oil LCO ; Pt-Ir catalyst; catalyst characterization; aromatic sulphur compounds; GC-SCD; distribution; analysis;

    Abstract : The global oil refining industry with its present shift inproduct distribution towards fuels such as gasoline and dieselwill most likely hold the fort for many years to come. However,times will change and survival will very much depend onprocessing flexibility and being at the frontiers of refiningtechnology, a technology where catalysts play leading roles. READ MORE

  3. 3. Experimental Studies on Using Butanol and Octanol Isomers as Drop-in Fuels for Diesel Engines

    University dissertation from Stockholm : Kemiteknik

    Author : Tankai Zhang; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The increasing importance of transportation in modern societies has caused fossil fuel consumption to increase greatly in recent decades. However, burning fossil fuels in internal combustion engines can lead to high emissions of greenhouse gases, which cause climate change. READ MORE

  4. 4. An Experimental Study of Fischer-Tropsch Fuels in a Diesel Engine

    University dissertation from Stockholm : Kemiteknik

    Author : Monica Larsson; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Alternative Fuels; Fischer-Tropsch; GTL;

    Abstract : Alternative fuels for Diesel engines include ester-based fuels (derived from sources such as rapeseed, soybeans and palm oil), dimethyl ether, and various synthetic fuels. Use of these fuels could contribute to a cleaner environment, reduce global warming and improve the human health by reducing levels of harmful emissions. READ MORE

  5. 5. Fischer-Tropsch and FAME Fuels as Alternatives for Diesel Engines; an Experimental Study

    University dissertation from Stockholm : Kemiteknik

    Author : Monica Johansson; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Emissions; SME; Fischer-Tropsch; NOx; Combustion; Alternative fuels; Soot; Biodiesel; RME; FAME; GTL; PME;

    Abstract : Research into alternative fuels is necessitated by our heavy reliance on limited oil reserves and increasingly strict emissions legislation. The studies reported in this thesis involved conducting engine tests using alternatives to fossil Diesel fuel in both heavy-duty and light-duty single cylinder engines. READ MORE
