摘要

目前國內市售無鉛汽油油品特性，主要是以掺配重組油與裂解油的類型為主，因重組油內含有大量芳香烴，而裂解油內含有大量烯烴，故對於引擎性能特性及燃燒效率上皆不盡相同，以致影響引擎性能、燃料消耗率、廢氣排放和燃燒特性。本研究使用掺配重組油和裂解油兩種不同市售的92、95和98無鉛汽油為燃料，來探討其對於引擎性能、燃料消耗率、廢氣排放和燃燒特性等的比較分析。經實驗結果顯示，掺配重組油為主的汽油於引擎惰速之CO、HC、CO2和NOX排放量較裂解油為主的汽油分別增加5.4%、0.2%、3.1%和1.2%，而各轉速及節氣門開度下對於引擎馬力和扭力、燃料消耗率以及CO和NOX的排放量均較裂解油為主的汽油分別增加0.3%、0.9%、2%、9.8%和8%，而掺配裂解油為主的汽油對於CO2和HC的排放量均較重組油為主的汽油分別增加4.4%及2%。

At present, fuel properties of unleaded gasoline sold in the market is primarily made up of Reformate and FCC-based gasoline. Because Reformate contains a huge amount of aromatic hydrocarbons while FCC-based gasoline contains a large amount of olefin, this causes differences in duo’s engine performance characteristics and combustion efficiency. This in turn affects the engine’s performance, fuel consumption rate, exhaust emission, and combustion characteristics. This study uses Reformate and FCC-based 92, 95, and 98 unleaded gasoline sold in the market as its fuel and makes a comparative analysis of the two’s effect on engine performance, fuel efficiency, exhaust emission, and combustion characteristics, among others. Results of the experiment showed that the CO、HC、CO2 and NOX exhaust emission at engine idle speed of Reformate-based gasoline increase by 5.4%、0.2%、3.1% and 1.2% respectively compared to FCC-based gasoline, at various engine speed and throttle angle, the engine power and torque, fuel efficiency, as well as the concentration of CO and NOX exhaust emission of Reformate-based gasoline increased by 0.3%, 0.9%, 2%, 9.8% and 8% respectively compared to FCC-based gasoline. In addition, the concentration of CO2 and HC exhaust emission of FCC-based gasoline showed an increase of 4.4% and 2% compared to Reformate-based gasoline.
