隧道用柴油机排气净化装置的研究

Study of purifying exhaust gas equipment for diesel engine used in tunnel

在分析了氮氧化合物光化学反应的基础上，提出了隧道用柴油机可以采用热反应器来实现机外废气净化，并介绍了热反应器的基本构造、原理。

In this paper, the photochemical reactions of Nox are analysed. It is pointed out that heat-reac-torcan be taken in the diesel engine used in tunnel to purify exhaust gas. The basic principle and const ruction of heat-reactor are also introduced.
