摘要： An apparatus and method for individually detecting NO and NO 2 concentrations as NO X components of an object gas. An NO concentration corresponding value is obtained from a first detection element not having a reduction section. An NO concentration corresponding value is obtained from a second detection element having a reduction section, and having an NO 2 /NO sensitivity ratio greater than that of the first detection element. The difference ΔC between the NO concentration corresponding values of the two detection elements is obtained, and divided by the difference ΔS between the NO 2 /NO sensitivity ratios of the two detection elements, whereby an NO 2 concentration corresponding value is obtained. A value obtained by multiplying the NO 2 concentration corresponding value by the NO 2 /NO sensitivity ratio of the second detection element is subtracted from the NO concentration corresponding value of the second detection element, whereby an NO concentration corresponding value is obtained.
摘要翻译： 用于将NO和NO 2浓度分别检测为目标气体的NO X成分的装置和方法。 从不具有还原部的第一检测元件获得NO浓度对应值。 从具有还原部分的第二检测元件获得NO浓度对应值，并且具有大于第一检测元件的NO 2 / NO灵敏度比的NO 2 / NO灵敏度比。 获得两个检测元件的NO浓度对应值之间的差“C”，除以两个检测元件的NO 2 / NO灵敏度比之间的差“S”，得到NO 2浓度对应值。 通过将NO 2浓度对应值乘以第二检测元件的NO 2 / NO灵敏度比而获得的值从第二检测元件的NO浓度对应值中减去，从而获得NO浓度对应值。
