林区道路运材汽车排放污染物监测系统设计1）

摘要

In the north woodland of China, because of the serious pollution emissions caused by poor road conditions and long-term overloading of wood trucks, we designed a kind of automobile exhausts pollution monitoring system for wood trucks, including hardware system and software system, and studied the emission characters of wood truck.The emission contents of CO and HC decline with the increase of vehicle speed, and those of CO, HC and NOx increase with the increase of ac-celerated speed .%针对我国北方林区道路路况条件差、运材汽车长期重载满负荷行驶，导致尾气排放污染严重的实际问题，以林区运材汽车为研究对象，设计了一种尾气排放污染监控系统，完成了系统硬件设计和系统软件开发。利用车载检测系统进行了林区运材汽车行驶排放特性研究，得出运材车辆行驶工况与排放污染物的关系：随着车辆运行速度的增加，CO和HC逐步降低；随着加速度的增加，CO、HC、NOx的排放值均变大。
