本文介绍了一个热电冷却，连续波（cw），单模分布反馈（DFB）量子级联激光器（QCL）的应用，实时，原位汽车发动机排气监测一氧化氮。在静态汽油机试验台上进行了试验，在该试验台上，发动机的工作条件可以以受控的方式变化。结果显示了一氧化氮浓度对发动机条件的响应。进一步多物种原位测量的前景进行了讨论。
This paper describes the application of a thermoelectrically cooled, continuous wave (cw), single mode distributed feedback (DFB) quantum cascade laser (QCL) to the real-time, in situ vehicle engine exhaust monitoring of nitric oxide. Experiments have been carried out on a static gasoline engine test bed where the engine operating conditions can be varied in a controlled manner. Results show the response of the nitric oxide concentration to engine conditions. The prospects for further multispecies in situ measurements are discussed.
