随着汽车发动机新技术的应用,以及各国环保法规的日益严格,对于汽车尾气排放检测采用了更先进的高科技手段,因而使得汽车尾气转化催化剂在技术处理上将向以下方面发展: 首先,为提高燃料效率和减少尾气中CO的排放,汽车发动机将采用贫燃技术。据称,将比一般发动机的燃料经济性高出20％～25％。由于氧气过剩,因而如何将NOx还原脱除就成为一个技术难题。目前,正在研究的解决方
With the application of new technology of automobile engines and the increasingly stringent environmental regulations in various countries, more advanced high-tech means are adopted for the detection of automobile exhaust emissions. As a result, the automobile exhaust gas reforming catalysts will be developed in the following aspects: First, Improve fuel efficiency and reduce CO emissions from the exhaust, automotive engines will use lean burn technology. Allegedly, than the average engine fuel economy 20% to 25% higher. Due to the excess oxygen, how to remove NOx reduction has become a technical problem. At present, the solution is being studied
