Abstract
Tail pipe emissions and evaporative emissions were measured from 4 passenger cars which are conformed most
recent exhaust gas emission regulations. The VOC tailpipe emissions from three vehicles were slightly high compared
with their certification results. The evaporative emissions were well below from the regulated value. The total amount of
VOC emission from cars was estimated from the experimental results and questionnaires for car users about the mean
travel distance in a year. As for results, 53 % in the total VOC emissions were emitted by the evaporative emissions.
The estimated emissions of the VOC from the gasoline vehicles were almost 3 % in total VOC emission in Japanese
society.
