摘要:
针对简易瞬态工况法机动车尾气排放检测过程中层出不穷的违规检测现象,为对其检测过程实施有效监管,通过分析简易瞬态工况法的检测原理,筛选出可用于监管的车辆基准质量、(CO+CO2)浓度、O2浓度、实时检测尾气流量4个参数,分析其用于监管的原理和理由,并通过五气分析仪漏气实验和实测尾气流量异常案例验证其监管可行性,以期为监管部门提供可运用于实际监管工作的有效策略。

Abstract:
In order to supervise effectively to avoid violation phenominon during the testing process of emissions from vehicles under short driving mode conditions, 4 parameters has been sieved out for supervision based on the testing principle of short driving mode conditions, which includes the reference mass of vehicle, the concentration summation of CO and CO2, the concentration of O2 and the flow rate of the vehicle exhaust fumes. The principles and reasons of its application in supervision has been expounded, and the feasibility of its supervision has been verified by the leakage experiment of five gas analyzer and the real case on abnormal flow rate of exhaust fumes, which is expected to put forward effective supervision strategies that can be applied to the actual supervision work for the supervision department.
