摘 要
利用現行市售的九二無鉛汽油為標準,調製了基準油,高苯油,高硫油與高芳香 油等,各以兩部不同廠牌的二行程機車進行惰速、CNS 11386行車型態與引擎性能等之測試與分析。

The motorcycle is one of the most popular transportation in Taiwan. The number of motorcycles in Taiwan is more than ten million. About half of the quantities, 5 million, are two-stroke motorcycles. The exhaust emission of motorcycles pollutes the environment very much, especially in the city. There is a regulation to restrict the exhaust emission of HC, NOx and CO. However, the existing potential toxic materials, such as benzene and aldehydes, would affect people's health as well. Thus, the objective of the project was to develop a low benzene fuel applied to the motorcycles and analyze the exhaust emission.
Based on the commercially available #92 unleaded gasoline, there were four fuels, base (low-benzene), high-benzene, high-sulfur, and high-aromatics fuel, respectively, developed and tested in this research. Six of two-stroke motorcycles from two companies were used in the research. Two of them were used for idle emission test, two for engine performance test and two for CNS 11386 test.
The results showed that the base fuel applied to the two-stroke motorcycles could reduce the emission of CO tremendously as well as the emission of HC and benzene. Numerically estimated the performance of the base fuel in Taiwan, it would reduce the annual emission of CO by over 17000 tons, HC by 1760 tons, and benzene by 3700 tons, respectively. On the other hand, it would increase annual emission of CO2 by 4600 tons, NOx by 345 tons, and aldehydes by only 29 tons. However, the increased emissions were much less than the reduced ones. In addition, the fuel consumption was increased 2km/l per motorcycle using the base fuel. The horsepower and torque of a motorcycle using the base fuel stayed at the regular lever as well. Therefore, the low benzene fuel provided a significant contribution to the environment and it should be applied to the commercial fuel system as soon as possible.
