Effect of Oxidation Catalyst and Particulate Matter Catalytic Oxidizer on Diesel Pollutants NOx and PM

柴油机的不断发展也给人类和地球环境带来了日益严重的污染问题。为了满足日益严苛的排放法规和更高的性能要求,本文重点通过ESC试验循环和稳态满载试验,研究不同的氧化催化器及颗粒物催化氧化器组合对柴油机污染物中的NOx和PM的影响。

Diesel engines have more power,economy,and reliability advantages than petrol engines,alleviating human resource and environmental problems,and therefore their market share in the automotive industry is constantly increasing.However,the continued development of diesel engines has also caused an increasing pollution problem for humans and the Earth's environment.To meet increasingly stringent emission regulations and higher performance requirements,this paper focuses on the impact of different oxidation catalysts and particulate matter catalytic oxidizer combinations on NOx and PM in diesel engine pollutants through ESC test cycles and steady state full load tests.
