Description
Technical field
The present invention relates to analysing tail gas of vehicle field, specifically a kind of analysing tail gas of vehicle system.
Background technique
With rapid economic development, the atmosphere pollution such as a large amount of pernicious gases, dust are also increasingly severe.The whole nation was more in recent years
Secondary generation wide range of haze shows that haze, acid rain and photochemical fog for frequently occurring etc. are big according to the data that Chinese Ministry of Environmental Protection issues
Gas pollution problem all has close relationship with vehicle exhaust emission.
2 months 2016, national environmental protection portion about air pollution treatment report, it is noted once again that Motor Vehicles Development
One of the main source of urban atmospheric pollution object is had become, country will reinforce administering the law enforcement power of tail gas pollution of motor-driven vehicle regulation
Degree, and following measures will be taken: " The Law of the People's Republic of China on the Prevention and Control of Atmospheric Pollution " is executed from January 1st, 2016,2017 1
It is nationwide interior by whole five standards of state of enforcement from the moon 1, motor-vehicle tail-gas is reinforced using type centrificate system to new production vehicle
Effective implementation of I/M system accelerates the sampling observation of superseded motor-vehicle tail-gas and infrared remote sensing monitoring law enforcement to yellow mark vehicle.
I/M system is that advanced industrial country and area carry out mandatory periodic detection to in-use automotive in the world, and to appearance
The vehicle of failure force the system of repairing.From following China's automobile increment and ownership control trend analysis and system
From the point of view of implementation result, accelerate the I/M system for implementing in-use automotive field, plays vital work to automobile pollution discharge is reduced
With.From future automobile increment and ownership trend, China's car ownership about 1.72 hundred million at present, according to National Information Center
Conservative prediction, the year two thousand twenty China car ownership are about 2.5 hundred million, if plus the factor, 2017 ~ the year two thousand twenty new car is eliminated year by year
Increment about every year on average 24000000.
Once expert reveals, they have found that the discharge amount of pollution of in-use automotive cannot simply be weighed with discharge standard
Amount, the vehicle of different mileages travelled, different service conditions is multifarious in pollutant emission, and highest differs hundred times, high dirty
Though contaminating the 20% of the insufficient total vehicle of vehicle fleet, its bring discharge amount of pollution accounts for 60% or more of gross contamination discharge amount.
Developed countries have been carried out I/M project evaluation system, and China is due to maintenance technique scarce capacity and mating political affairs
The shortcoming of plan regulation, most cities are still under open loop management mode, and I/M system is caused to perform practically no function.
Although relevant departments reinforce detection and improvement to automotive emission in recent years, but still have a large amount of car owners by
" ox " gets by under false pretences." ox " installs makeshift device usually after charge for vehicle, allows to cross and examine by environmental protection tests
It removes again afterwards.One exceeded vehicle of tail gas is equivalent to the exhaust emissions amount of tens even several hundred trolleys, this is to air
Environment causes greatly to destroy.
Currently, motor vehicle exhaust emission control and improvement have become world's important topic, and China starts late in this respect,
Many technologies are also in exploration and experimental stage, administer that vehicle exhaust is exceeded also rests on according to artificial experience decision problem at present
Place, and the method for taking corresponding maintenance measures, this requirement to maintenance personal is very high, at least needs 8 years or more correlations
Working experience could be competent at.However, can analyze, judge, the senior technician of guide maintenance often has culture difficult,
The characteristics of asking wages treatment excessively high, easily job-hoping, while for vehicle exhaust maintenance, lack corresponding experience and theories integration.
