Abstract:This paper mainly introduces the application of nitrogen oxide analyzer in diesel vehicle emission detection, and analyzes the factors that affect the inspection and testing results. Through the analysis, the motor vehicle inspection and testing institutions further improve the accuracy of nitrogen oxide detection results, to ensure that the emission results are more real and effective.
Key words:nitrogen oxides, diesel vehicles, pollutants
GB3847-2018《柴油車污染物排放限值及測(cè)量方法(自由加速法及加載減速法)》中規(guī)定,柴油車排氣污染物加載減速法檢測(cè)的排放指標(biāo)主要有顆粒物(光吸收系數(shù))和氮氧化物(NOX)。(剩余3595字)
