In this research, an amplifier circuit was comprised of changing and transferring voltages from second coil to high voltage of generated spark for low voltage, and experiment to expand ranges of rarefied flow regime made progressed by plasma spark was studied to aimed for realization. Part of main components used in experimental device composed a system with DC 12V battery, iridium ignition plug, nonresistance ignition plug, stick ignition coil, high voltage cable and closed vessel combustor. The pulsed input signal of spark accurately realized a control to value of flow rate about combustion parameters of the oxygen, propane, nitrogen as installation with mass flow meters. Experimental method should be inserted in chamber as mixture of oxygen and propane gases before generating spark and the photographing data extracted of the AFR, compressed and combustion pressure, injection rate of nitrogen gas and flames. From the experimental results, it could be obtained to be expanded to the combustion pressures and flames from experimented plasma spark type as installed of circuit that voltage can amplify in comparison with existing point spark type. |
