碩士 === 國立臺灣大學 === 生物產業機電工程學研究所 === 94 === The most influence on human body is aerosol from motor vehicle emission. Taiwan motorcycle''s quantity is up to more than 13,800,000, the density of motorcycle is the highest in the world. To control the emission from motorcycle can make air quality obviously improve. The private service gas station is popularized in Taiwan. Some unworthy businessman adds solvents to earn the price differential in the oil. This study used 95 unleaded gas of different companies, add different proportion of xylene. Utilize the Electrical Low-Pressure Impactors (ELPI) to measure particles number concentration and waste gas composition with Combustion Analyzers. Add the high proportion of the xylene really causes the quantity of particle of the waste gas to rise high concentration by the experimental result. The particle diameter of peak value is not changed with the change of the additive. The mode of aerosol is between 0.04~0.2μm. The number conceration of the particle rises as the rotational speed of the engine increases. Different gears will influence the quantity of particle with the same rotational speed. With the increase of the rotational speed of the engine , it can reduce the production of the particle in the proper change gears. Gasoline with high proportion xylene is harder to start an engine. Carbon monoxide and sulfur dioxide in the engine waste gas are extremely low. Because of the experiment use hot-engine test fuel can be burned completely and 95 unleaded gasoline almost have no sulfur.
