Study On The Execution Way Of The 2005 Emission Standard In Jin' Hua City

There is growth rapidly of the automobile's hold quantity in our country since 1980's,the air pollution resulted from the automobile creates unceasingly aggravates,the automobile discharges the pollution to pose the serious threat to the city atmospheric environment.It is extremely important that carries on the emission examination for in-use car and control the pollution of the automobile actively.This paper introduces the automotive emission standard of the overseas and our country,compares with the emission standards of new car and in-use car, outlines the history of the emission standard in-use car was established in our country and the concrete implementation situation.It also analyses the applicable scope,limits,operating mode and instrument of the national 2005 emission standard.The present situation of the automobile emissions in Jin'hua city,the condition of carrying on the new standard,compared with each kind of measurement, the problem meets of the process are analysed.In view of the current economical level and the vehicle condition in Jin'hua city.according to "The Test Standard of Emission in-Use Vehicle",Jin'hua city's regular test system should be the basic type.The regulation and requirement of the new national standard,execution of the national standard in Jin'hua city was divided into transition stage and apply stage.The goal is from idle speed condition to two-speed idle condition for the vehicle equipped with ignition engine and with the free-speed condition for the vehicle equipped with compressed ignition engine.The two-speed idle condition is analysed from every way.Through the test result analysis and the cost comparison with three kind of simple operating mode method,decided the apply stage,the goal is from two-speed idle condition to simple driving mode condition for the vehicle equipped with ignition engine and from free-speed smoke condition to Lug-down driving mode condition for the vehicle equipped with compressed ignition engine.It is also can carries on the assistance examination with remote sensing or with the eye.The examining procedure,the data processing, the personnel disposes,the handles of the cannot achieve standard vehicle,the cost benefit are also elaborated systematically.
