车载排放测试技术的研究综述

Study on Portable Emission Measurement System

现行的车辆排放污染物测量方法和设备主要是基于排放实验室测量。但是实验室测量由于其受场地条件和测功机测量范围等方面的限制,不能很好的反映车辆在实际使用时的排放状况。本文阐明了车载排放测试技术是一种实际行驶条件下对车辆排放特性进行测量的方法,能得出车辆在实际工况条件下的排放数据,而不影响车辆的正常使用。这对我们了解车辆的排放因子、评估在用车量对城市排放总量的影响、为我们的研究及政府管理部门制定排放法规和政策很有益处。

Nowadays, the measurement method of vehicle emission pollutant and the measurement equipment are mainly used in the testing laboratory. But the laboratory measurement can not clearly reflect the vehicle emission level under real-world condition, for the restriction of their place and equipment. The technology of on-board emission t is the method to test the vehicle emission characteristic in actual driving cycle, so it can obtain the emission data about the vehicle realworld driving, and does not influence the normal use of the vehicle. It＇s important for us to understand of emission factor and evaluate the in-use vehicle total emission. It＇s also benefit to our research and our government to make the policy.
