碩士 === 國立交通大學 === 工學院碩士在職專班精密與自動化工程組 === 97 === The main focus of this study is to design, researching applications, and methods of plasma reforming of hydrocarbon fuel on four stroke motorcycle engines. The overall apparatus includes plasma recombination device, fuel and air supply system, and data analyzer instruments. The plasma recombination device consists of signal generator, reaction chamber, and gas collection chamber. The fuel and air supply system include gas contain in steel chamber, gas flow meter, and nozzle. The data analyzer instruments contain gas chromatographer, oscilloscope, and current meter, etc. The experimentation settings are O2/C ratio (0.2~0.6), the electro arc frequency (200 Hz) , the fuel flowing rate (10~50mL/min) , and the electro arc spacing (5mm~10mm). The experimental data illustrates that using appropriate setting of reaction chamber diameter, elector arc spacing, and methane flow rate, able to generate better result of hydrogen concentration and flow rate. The produced hydrogen concentration in the reaction chamber increase as the flow rate decrease. Under the appropriate system setting, the hydrogen concentration is able to reach 38.42 Vol% and hydrogen flow rate of 143.58 mL/min Another part of the study is discussion of effects on mixing high concentrate hydrogen into four stroke motorcycle engine, utilized the steel reaction chamber for high concentrate hydrogen combination to control hydrogen gas ratio (2~12%), and flow rate of high concentration hydrogen, etc. Experiment maintains the original fuel system of motorcycle engine. Modifies the air intake system for hydrogen combustion, with engine speed of 3000~6000rpm, and the engine throttle is opening 1/6-6/6degree.
