摘要
针对柴油机满足国IV标准的需要,探讨了目前国际上可以实现国IV标准的主要技术路线的优缺点。在某国产新机型(国Ⅲ标准)上对SCR技术进行试验验证,结果表明:在国Ⅲ机型上加装SCR系统,既可以达到国IV标准又可以改善燃油经济性。得出了柴油机实现国IV标准的SCR技术适合中国市场发展的结论。
To meet the phase Ⅳ emission standards for diesel engine in China, the advantages and disadvantages of two technical routes were analyzed, and then the emission test experiment was carried out on a new engine prototype. The test result shows that the application of the SCR system on a China Ⅲ diesel engine can not only achieve phase Ⅳ emission standards of China, but also improve the fuel economy. Finally, it is concluded that the SCR technology is more suitable for the market development in China.
