提高汽化器式发动机的经济指标是汽车制造业的长期任务。虽然这方面已取得很多成绩,但这个问题仍具有很大的现实意义。很多国家,例如美国,已经实行汽车燃料消耗定额,而且定额逐年严格。1978年燃料消耗定额是每100公里13.1升,1985年每个公司汽车总量的平均燃料消耗定额将达到每100公里8.5升,这相当于欧洲较好的小排量汽车燃料消耗量。 To improve the economic indicators of carburetor engines is the long-term task of the automobile manufacturing industry. Although many achievements have been made in this regard, this issue still has great practical significance. In many countries, such as the United States, the quota for the consumption of motor fuel is already fixed, and the quotas are rigor each year. In 1978, the fuel consumption quota was 13.1 liters per 100 kilometers. In 1985, the average fuel consumption per company total car will reach 8.5 liters per 100 kilometers, which is equivalent to the better fuel consumption of small cars in Europe.
