Recently,using catalyst for simultaneous removal of diesel soot particulates and NOx is a focus.The experiment,which uses La0.9K0.1CoO3 as catalyst,had been done on engine bench.The results of the test has proved the performance of simultaneous removalling soot particulates and NOx from diesel of the catalyst;and it will become a strategy to face to the stricter Emission Regulations to use the characteristics of the catalyst,which can adsorb NOx in low temperature.However,there is some distance from applica...
