|Study on the Monitoring Strategy of Vehicle Exhaust Emission Detection under Short Driving Mode Conditions
Qingshen County Energy Conservation Supervision Center，Meishan，Sichuan 620460，China
|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.
