【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,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。本文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,柴油车尾气净化催化剂的问题与展望。更多还原

【Abstract】 Automotive have been limited in productivity,automotive should have been energy saving and emission reduction in exhaust,because automotive have being discharged a large of CO2,O3 in atmosphere been destroyed,air temperature in the earth become warm and climate been unusual .Diesel have a high of efficiency in thermal energy,a large of power,and have a very good in economy and reliable. So,a large number diesel have been produced fast. The paper has been introduced in development of catalyst in diesel exhaust purification,made use of principle of catalyst,composition of catalyst,the problem and the wish of catalyst in diesel exhaust.更多还原
