The development engine should be set to high performance, low fuel consumption and low emissions. The efficient engine of pollution makes the development of engine efficiency very important. In order to improve engine efficiency, the most effective and fast method is to improve the engine geometric compression ratio. This study is aimed at increasing the compression ratio of small single-cylinder four-stroke gasoline engines, developing performance under different high compression ratios, fuel consumption, emission, combustion analyzing , and exploring the ultimate compression ratio for small single-cylinder four-stroke gasoline engines. Impact and benefits. The experimental results show that under full load, the performance of the high compression ratio engine is improved, and the fuel consumption is improved. However, due to the impact of the knocking, the benefits of CR11.9 and CR13.1 are similar. Although the emission pollution is different due to different working conditions, the overall trend is that the higher the compression ratio, the worse the sewage discharge. Under partial load, the high compression ratio has better combustion parameters, which improves fuel consumption. Emissions pollution In addition to any difference in CO, both HC and NO are negative benefits of high compression ratio. LEE,CHO-YU 李卓昱 2019 學位論文 ; thesis 64 zh-TW
