Reducing ozone in the atmosphere is one of the biggest issues in Japanese air pollution. It is known that ozone is produced from the reaction of Volatile organic compounds (VOCs) with NOx. Thus the effect to reduce VOCs emission in the air was carried out. From this point of view, hydrocarobon emission from the automobile exhaust has been reduced. On the other hand, Evaporative VOC emission from automobile was not focused so much, and there is a little information about that. Recent research shows that much of VOCs emissions from recent gasoline vehicle is by evaporation latter than emission from tail pipe. So in this study, evaporation emission from gasoline vehicle was observed using laser ionization Time of flight mass spectroscopy.
