碩士 === 國立高雄應用科技大學 === 工業工程與管理系 === 106 === The MOTC (Directorate General of Highways) statistics in 105 years, the total number of motor vehicles registered 21,489,722 units, of which there are 7,810,600 cars and 13,679,122 motorcycles. That is, every hundred people that 91.4 people have motor vehicles. That is, every one hundred people that will 91 people have motor vehicles. The motorcycle occupancy rate is quite high in Taiwan, with the exhaust emission is also considerable, so in order to improve the motorcycle engine performance and reduce emissions to achieve green environmental protection. In this study, a cooling and heating device is introduced into the locomotive fuel system to allow the mixture to be adjusted, cooled, or heated into the engine compartment to allow the engine to increase combustion efficiency The study of the internal combustion engine fuel injection engine temperature control characteristic performance of using thermoelectric wafer produced double hot and cold temperature, cooling and heating control system for locomotive fuel, according to the principle of the second law of thermodynamics of changing fuel temperature of the internal combustion engine combustion efficiency is improved, and adjusting the mixed steam temperature into the combustion chamber, combustion to reduce nitrogen oxides generated indoors the pollutant gases, increase fuel atomization effect and improve combustion efficiency of fuel system The experimental results are available, the lean burn and high temperature fuel high temperature effect can effectively reduce HC, CO. Low-temperature fuel effect effectively reduce the combustion temperature can significantly reduce the NO emissions, but it caused incomplete combustion situation. In the horsepower test, high-temperature fuel will improve the dynamic curve, but when the combustion temperature is too high, the dynamic curve will be opposite. At this time, switching to the low-temperature fuel dynamic curve will not only recover but also improve.
