  1. 1. On Alternative Fuels for Internal Combustion Engines : A study of biodiesel, gaseous methane and methanol

    Författare :Ludvig Adlercreutz; Andreas Cronhjort; Ola Stenlåås; Magnus Sjöberg; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gaseous methane combustion; spark ignition; single cylinder research engine; particle number; particle emissions; oil ash content; CO2; Green House Gases; engine testing; engine development; emissions; combustion chamber design; injector fouling; environmental impact; road transportation; Machine Design; Maskinkonstruktion;

    Sammanfattning :  This thesis covers some of the environmental impacts of internalcombustion engines running on alternative fuels. The focus of thestudies conveyed is the reduction of greenhouse gases and particleemissions, as these two factors are of great importance for the pathsthat road transportation is facing. LÄS MER

  3. 2. Emission and Deposit Formation in Direct Injection Stratified Charge SI Engines

    Författare :Håkan Sandquist; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; cycle-resolved measurements; deposit formation; direct injection; stratified charge; hydrocarbon emissions; SI engines; fuels;

    Sammanfattning : A promising approach to increase the efficiency of the spark ignition (SI) engine is to inject the fuel directly into the cylinder to form a stratified charge. There is a potential to reduce the fuel consumption at low speeds and loads by 20 - 25% compared with conventional SI engines with stoichiometric homogeneous charge. LÄS MER

  4. 3. Filtration of soft particles

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

    Sammanfattning : 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. LÄS MER

  5. 4. Entrained flow gasification of biomass: soot formation and flame stability

    Författare :Burak Göktepe; Kevin Whitty; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Sammanfattning : Entrained flow gasification (EFG) is a well-proven, commercially available technology for large scale coal gasification processes, with a production of a high quality syngas (a mixture of carbon monoxide (CO), hydrogen (H2), carbon dioxide (CO2), methane (CH4) and other compounds). For biomass, the process is still under development and there are several hurdles that must be cleared before it can become commercial. LÄS MER
