  • An evaluation of the use of Alcohol Fuels in SI engines in terms of performance, emission and combustion characteristics: A review
    Fuel, 2021
    Co-Authors: Meltem Göktaş, Mustafa Kemal Balki, Cenk Sayin, Mustafa Canakci
    Abstract:

    Abstract Vehicles powered by fossil-Fuels cause to increase harmful gases in the environment and decrease petroleum reserves. To minimize these damages, many researchers submitted that one of the alternative Fuels which could obtain desired performance and release minimum rates of exhaust emissions in spark-ignition (SI) engines is Alcohol fuel, and they carried out many experimental studies. In this review study, experimental studies which indicate the changes in performance parameters, emissions such as hydrocarbon (HC), carbon monoxide (CO), carbon dioxide (CO2) and nitrogen oxide (NOx), and combustion characteristics by using Alcohol fuel in SI engines were investigated in detail and the increments and decrements in related parameters were indicated in separated tables. In addition, the graphs which indicate how much alteration obtained by using what kind of Alcohol and what amount of Alcohol in comparison with using gasoline were created.

  • the effect of different Alcohol Fuels on the performance emission and combustion characteristics of a gasoline engine
    Fuel, 2014
    Co-Authors: Mustafa Kemal Balki, Cenk Sayin, Mustafa Canakci
    Abstract:

    Abstract In this experimental study, the effect of Alcohol (ethanol and methanol) use on the performance, emissions and combustion characteristics of a low power single-cylinder engine described the rated power output of the engine e.g. 2 kW were investigated and the results were compared with conventional gasoline operation. The tests were performed at full-throttle valve opening and variable engine speeds. The results show that the use of Alcohol Fuels increased the engine torque, brake specific fuel consumption (BSFC), thermal efficiency and combustion efficiency. In addition, the cylinder gas pressure and heat release rate occurred earlier; carbon dioxide (CO2) emission increased while hydrocarbon (HC), carbon monoxide (CO) and nitrogen oxides (NOx) emissions decreased.

  • development of solid oxide fuel cell materials for intermediate to low temperature operation
    International Journal of Hydrogen Energy, 2012
    Co-Authors: Jianbing Huang, Cheng Wang
    Abstract:

    Abstract The commercialization of solid oxide fuel cell (SOFC) needs the development of functional materials for intermediate-to-low temperature (400–700 °C, ILT) operation. Recently, we have successfully developed new electrolyte materials for ILT-SOFCs, including Ce 0.8 Sm 0.2 O 1.9 (SDC), BaCe 0.8 Sm 0.2 O 2.9 (BCSO) and SDC-carbonate composites. Compared with the state-of-the-art yttria-stabilized zirconia (YSZ), these materials exhibit much higher ionic conductivity at ILT range. Especially, SDC-carbonate composites show an ionic conductivity of 10 −2 to 1 Scm −1 between 400 and 600 °C in fuel cell environment. Some new cathode materials were investigated for above electrolyte materials and showed promising performance. Alternative anode materials were developed to directly utilize Alcohol Fuels. A dry-pressing and co-firing process was employed to fabricate thin SDC and BCSO electrolyte membranes as well as thick SDC-carbonate composite electrolyte with acceptable density on anode substrate. Many efforts have also been made on fabrication of larger-size planar cells and exploitation of reliable sealing materials.

  • High-Temperature Chemistry in Solid Oxide Fuel Cells: In Situ Optical Studies.
    Journal of Physical Chemistry Letters, 2012
    Co-Authors: Michael B. Pomfret, Robert A. Walker, Jeffrey C. Owrutsky
    Abstract:

    Solid oxide Fuels cells (SOFCs) are promising devices for versatile and efficient power generation with fuel flexibility, but their viability is contingent upon understanding chemical and material processes to improve their performance and durability. Newly developed in situ optical methods provide new insight into how carbon deposition varies with different hydrocarbon and Alcohol Fuels and depends on operating conditions. Some findings, such as heavier hydrocarbon Fuels forming more carbon than lighter Fuels, are expected, but other discoveries are surprising. For example, methanol shows a greater tendency to form carbon deposits than methane at temperatures below 800 °C, and kinetically controlled steam reforming with ethanol at high temperatures (∼800 °C) is less detrimental to SOFC performance than operating the device with dry methanol as the fuel. In situ optical techniques will continue to provide the chemical information and mechanistic insight that is critical for SOFCs to become a viable energy...
