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

    Författare :Per Risberg; David E. Foster; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Auto-Ignition Quality; RON; MON; Cetane Number; HCCI; CAI and Fuels; Other engineering mechanics; Övrig teknisk mekanik;

    Sammanfattning : 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. LÄS MER

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

    Författare :Ulf Nylén; KTH; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  4. 3. ɸ‑sensitivity : A step forward in future fuels evaluation

    Författare :Nika Alemahdi; Förbränningsmotorer; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Equivalence ratio; ɸ‑sensitivity; Cooperative Fuel Research engine; Method development; Biofuels.;

    Sammanfattning : Internal combustion engine is a developed and established technology whichcontributes largely to the transportation of goods and people. In one hand, theburning of fossil fuels is the main reason for the combustion engines to beconsidered unsustainable while on the other hand, the combustion behaviour ofrenewable fuels is not fully understood yet.

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

    Författare :Tankai Zhang; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : 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. LÄS MER

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

    Författare :Monica Larsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Alternative Fuels; Fischer-Tropsch; GTL;

    Sammanfattning : 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. LÄS MER
