针对日益严格的尾气排放限制条令,人们希望有新的发明创造来减少汽车的排放污染。根据欧Ⅳ标准的要求,到2005年底前,氮氧化物(N O x)的排放量将减少30%(该标准适用于额定装载量在3.5t以上的车辆)。另外,欧Ⅴ标准也已开始着手设定2008年的排放标准,届时将要求N O x的排放量在欧
In response to the increasingly stringent exhaust emission restrictions, people want new inventions to reduce vehicle emissions pollution. According to the requirements of Euro IV, NOx emissions will be reduced by 30% by the end of 2005 (this standard applies to vehicles with a nominal capacity of 3.5 tons or more). In addition, the European Ⅴ standard has also started to set the 2008 emission standards, will require N O x emissions in Europe
