The Contrast Of Measurement Methods Of Automobile Exhaust Pollutants

Due to the increasing depletion of oil resources, all countries in theworld in the development of new energy vehicles, despite its low carbon,energy saving, environmental protection, but its power efficiency is lowand has not been widely used, but the traditional gasoline engine anddiesel engine because of its large power, fuel economy is good, has beenwidely used in the world. With the car quantity increased year by year, thepollution of automobile exhaust pollution to the atmospheric environmentis becoming increasingly serious, automobile exhaust pollution hasbecome the main reason for the quality of atmospheric environmentpollution in the city.At present, the international automotive exhaust emission regulationsare mainly divided into the United States emission pollutants ofautomobile exhaust emission regulations, Europe and Japan AutomobileExhaust emission regulations, other countries basically refer to thesethree laws and regulations to develop national automotive exhaustemission regulations, our country mainly referred to the European car exhaust pollutants emission regulations. National Ministry ofenvironmental protection issued many relevant on emission pollutantsfrom automobile exhaust standard of value, To make scientific, accuratemeasurement of the emission of automobile exhaust pollution, the strictcontrol of vehicle exhaust pollutants, increase the automobile exhaustpollutant emissions on the atmospheric environment pollution control,must strengthen to the measurement for automobile exhaust pollutants.Therefore our country to have control, strict in discharge by automobileemission pollutant so, it is particularly important for measurementmethods for exhaust pollutants from automobile, measurement methodsfor exhaust pollutants from automobile is constantly updated, perfection.This paper introduces the reasons and the harm and automobileexhaust pollutant purifying technology of automotive exhaust pollutants,as well as in the method of measuring the gasoline vehicle exhaust.Measuring method of automobile exhaust pollutants into idle speedmeasurement method, double idle speed measurement method, simpleoperation and road remote sensing monitoring and on-boardmeasurement technology, remote sensing monitoring and measuringtechnology of road vehicle in our country at present no popularization. Formonitoring the effect comparison of idle, idle and simple condition ofmeasurement method of vehicle exhaust pollutants, accuracy analysis ofmeasurement results, in this paper, a large number of exhaust emission measurement and data comparison for different types of cars.From2008January-2012year in December at the national autoparts product quality supervision and Inspection Center (Changchun)electric car5different manufacturers, automobile exhaust emissionmeasurement of different specifications and types of the128vehicles,carburetor car3different manufacturers, different models andspecifications of the59vehicles, the engine exhaust were between1.3L-2.0L three sedan and hatchback, and service life is divided intodifferent vehicle service life; all models for the EFI cars and carburetorcars, are up to GB18285-2005"ignited engine automobile exhaustemissions limits and measurement methods" standard.Based on the comparison and study of the international three autocommon sewage discharge measurement method, combined with fulland accurate data, demonstrates simple condition method is themeasurement of emissions in three kinds of measurement methods is themost accurate and feasible. Through this article, can be more clearvehicle emission effectiveness measurement methods for exhaustvolume of science. The conclusion of this paper will provide China themeasurement methods of vehicle emission exhaust volume providesproved more accurate.
