摘要
汽车因排放大量的CO2气体,破坏了大气的臭氧层,造成了全球的温室效应,使整个地球气温变暖,气候异常,所以需要对汽车生产进行产能限制,同时对汽车进行节能减排。由于柴油车热效高、功率大,具有良好的经济性和可靠性,所以柴油车的生产现已得到突飞猛进的发展。介绍了柴油车尾气净化催化剂的发展过程、催化剂使用的原理及催化剂组成,并提出了柴油车尾气净化催化剂的问题与展望。
Automotive produces large of CO2, results in the destroy of O3 atmosphere, and then makes the temperature become warm and climate become unusual. For this reason, automotive is limited in productivity and it should be energy saving and emission reduction in exhaust. Diesel has a good economy and reliability, with a high thermal energy efficiency and a large power, so a large of diesel are produced. The development of catalyst in diesel exhaust purification, principle of catalyst, composition of catalyst, the problem and the outlook of catalyst in diesel exhaust are introduced.
