    The design of fuzzy expert system for emission parameters
    (2008) Saritas I.; Ciniviz M.
    The most important problem, which the world is face to face, is the environment pollution. The greatest reason of the pollution is the use of energy, especially the fossil fuel. Therefore the pollution of air, the soot emission which forms danger for human life and natural life and Nitrogen oxide emission that causes acid rain. Consequently decreasing emission is one of the important problems of our daily life. In this study; the effects of atomizing pressure and the alteration of CO2 portion in the air, the emission parameters, of a turbo diesel engine on nitrogen oxide and soot emission. It was researched and was completed with a fuzzy expert system method by using Mamdani type mechanism. Experiments were done for the same motor, were evaluated by comparing experimental outputs and the results of fuzzy expert system. The main object of the study is laying the groundwork for the real studies. In the correlation, which was applied between the outputs of the experiments and the outputs of the designed fuzzy expert system, the ratio of 99.87% was taken. It was also observed that the designed fuzzy expert system represented the outputs of experiments in the ratio of 98% according to the repeated two sided variance analyze.

    An experimental investigation on effects of methanol blended diesel fuels to engine performance and emissions of a diesel engine
    (2011) Ciniviz M.; Köse H.; Canli E.; Solmaz O.
    Considering strict restrictions on exhaust emissions of newly produced diesel engines, in this study, the effects of methanol and diesel fuel blends on compression ignition engine performance and exhaust emissions of a four cylinder, four stroke, direct injection, turbocharged diesel engine were experimentally investigated. Methanol-blended diesel fuels were ranged from 0 to 15% volumetric methanol content with an increment of 5%. The tests were performed by varying engine speed between 1000 min -1 to 2700 min -1 by an engine testing dynamometer. Results indicated that brake specific fuel consumption and nitrogen oxide emissions increased while brake thermal efficiency, carbon monoxide and hydrocarbons decreased relative to single diesel fuel operation with increasing amount of methanol in the fuel mixture. Effects can be visualized by data which were 49 and 47.5 kW for power, 169 and 190 g/kWh for brake specific fuel consumption, 33 and 30% for brake specific thermal efficiency, 0.21 and 0.18% for carbon monoxide, 7.15 and 8.1% for carbon dioxide, 8.02 and 6.1 ppm for hydrocarbons, 385 and 418 ppm for nitrogen oxides at 1600 min-1 in order of standard diesel fuel operation and fuel blend with 10% methanol content. © 2011 Academic Journals.
