抄録

The fuel economies for various kinds of automobiles have been investigated. According to the fuel economy based upon the department of transportation standard, the fuel economies in 2000 improved 9-23% compared to those in 1990 for each class of the curb weight. However, the total fuel economy in Japan, which were estimated from the both data of the total amount of fuel consumption and total killometrage in Japan from 1965 to 2000, show about 9 km/liter, and in the recent decade it became rather worse. The reason for this inconsistency is that the large size automobile became popular because of the inclination of user, anti-regulation of automobile tax, price down of fuel and so on. In order to improve the total fuel economy aiming the reduction of CO2 emission, two problems, which are "improvement of the fuel economy for the respective automobile" and "suppression of the over sizing of automobile", are examined.
