2. 1. The effects of long chain alcohol blends on engine performance and spray characteristics in CI engines

   Author : Josefine Preuss; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; spray characteristics; RME; drop-in bränslen; long chain alcohols; CI engine; HVO;

   Abstract : Replacing fossil fuels with alternatives derived from renewable sources is one way of meeting society’s increasing need for mobility while also significantly reducing greenhouse gas emissions from vehicles with internal combustion engines. To facilitate such a replacement, this thesis presents optical spray studies and engine experiments conducted to evaluate the potential of blends of biomass-derived alcohols and vegetable oils to serve as drop-in fuels for compression ignition engines.

4. 2. 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

5. 3. Energy Use, Efficiency Gains and Emission Abatement in Transitional Industrialised Economies: Poland and the Baltic States

   Abstract : This thesis is a study of how energy use and air pollution in Poland, Estonia, Latvia and Lithuania have been affected by the economic transition after 1989. It consists of six articles, which examine three different aspects of these changes. READ MORE

6. 4. Filtration of soft particles

   Author : Botond Csontos; Andreas Cronhjort; Hanna Bernemyr; Jim Barker; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine Design; Maskinkonstruktion;

   Abstract : The transportation industry relies heavily on fossil fuels, a dependency that isnot sustainable for the future. The easiest way to change this dynamics is to userenewable fuels, such as biodiesel or hydrotreated vegetable oils, which can be usedas drop-in fuel or blends, without engine modifications. READ MORE
