This paper describes an investigation in which a fuzzy control paradigm was applied to a small spark-ignition gasoline-fuelled internal-combustion engine, to achieve regulation of the fuel injection system. The control system determined the amount of fuel required from a fuzzy algorithm that used the engine speed and manifold air pressure as input values. The parameters of the fuzzy system cons...
To overcome the challenge of measuring the fuel ion ratio in the core (ρ<0.3) of ITER, a coordinated effort aiming at developing diagnostic techniques has been initiated. The investigated techniques are novel uses or further development of existing methods such as charge exchange recombination spectrometry, neutron spectrometry, and collective Thomson scattering. An overview of the work on the ...
Today the important challenge is to reduced energy crises and pollution problems , since the use of fossil fuel is continuously increasing due to growth in industrialization. For economic development of country and living standards. Hence there is need to find and alternative fuels to decrease the consumption of fossil fuel and reduce the emission emitted from fossil fuel which produces hazarda...
In recent years, hydrogen production from biomass has been optimized in fluidized bed conditions, and the steam gasification has become an area of growing interest because it produces a gaseous fuel with relatively higher H2 content which could be used in fuel cells, a new technology for the future to produce power in a much cleaner manner. The equivalence ratio is one of the most important ope...
Oxygen transport across the cathode gas diffusion layer (GDL) in polymer electrolyte membrane (PEM) fuel cells was examined by varying the O2/N2 ratio and by varying the area of the GDL extending laterally from the gas flow channel under the bipolar plate (under the land). As the cathode is depleted of oxygen, the current density becomes limited by oxygen transport across the GDL. Oxygen deplet...
The thesis presents a complete framework for the design of an individual cylinder air-fuel ratio (A/F) controller that aims to further reduce the exhaust emissions of modern automotive gasoline engines. It is well known that this type of controller relies on a correct estimation of the A/F of the individual cylinders. Otherwise, the control system can become unstable. Therefore, the conditions ...
To evaluate the utility potential of pretreated biomass in blast furnaces, the fuel properties, including fuel ratio, ignition temperature, and burnout, of bamboo, oil palm, rice husk, sugarcane bagasse, and Madagascar almond undergoing torrefaction and carbonization in a rotary furnace are analyzed and compared to those of a high-volatile coal and a low-volatile one used in pulverized coal inj...
