发动机的优化——汽车行业需要能在短期内将二氧化碳排放降低到140g／km的措施

Optimising engines—— The industry needs short-term solutions to bring CO2 emissions down to 140g/km

欧洲的汽车制造商未能达到其自定的增加新车燃油效率的目标。在90年代后期，汽车制造商同意将欧洲销售新车的二氧化碳排放降低。他们订下的目标是到2008年将二氧化硬排城水平降到140g／km。

European carmakers are failing to meet their voluntary. targets to increase fuel efficiency from new cars. In the late 1990s, car manufacturers agreed to reduce carbon dioxide emissions from new cars solcl in Europe. They set a target of 140g/km of CO2 by 2008.
