碩士 === 國立中正大學 === 機械工程所 === 97 === This study is about diesel engines at different speeds and the injection angle at different ignition timing on the dynamometer tests with using different proportions of bio-fuel that mixed by diesel and pyrolytic oil of scrap tires, theoretically calculate and measure the pollution gas exhausted by diesel engine and establishing the relationship of fuel-air ratio, ignition timing and emissions, like HC, CO, CO2, NOX,O2. According to the experimental results, increasing engine speed will reduce emissions of O2, but emissions of HC, CO, CO2, NOX are no consistent trend of change. With adding pyrolytic oil of scrap tire, emissions of HC, CO2 are improved, but emissions of CO and NOX change little. Advanced ignition timing reduces the amount of emissions of HC and CO , but increases the amount of emissions of NOX. By the results of this study can be used as the future of the establishment of the actual burning of diesel engines, gas emissions generated model reference.
