1, the computer inputs information and pays related testing fees. This link is carried out in the login booth, and the purpose is to assign detection lines according to the characteristics of vehicles, which are automatically completed by the computer.
2. Go to the designated detection line. The dispatcher guides the vehicle into the detection line designated by the computer, and the intermediate personnel have no right to change the detection line.
3. Confirmation information of the central control room. This link confirms that the inspected vehicle enters the correct detection line, otherwise it cannot enter the next link.
4. Implement tail gas detection. This link is carried out by the inspector according to the prompt on the computer screen, and the detection can be successful only if the operation is correct. The test results are uploaded to the server by the system.
5. After the inspection, go through the formalities in the lobby, and enter the window of examination, driving license seal and issuance sign with relevant materials. If it is unqualified, it needs to be repaired and rechecked.
Extended data
Automobile emission standards refer to the regulations on the contents of harmful gases such as CO, HC+ nitrogen oxides (hydrocarbons and nitrogen oxides) and PM (particulate matter, smoke and dust) emitted by automobile exhaust. From June 5438+1 October1day, 2004, Beijing changed the vehicle exhaust emission standard from the current Euro I to Euro II, and in 2008, the Euro III standard was officially implemented.
European standards are achieved through the emission regulations of the Economic Commission for Europe (ECE) and the emission directives of the European Community (EEC), namely the European Union (EU). ECE participating countries voluntarily approve emission regulations, and EEC or EU participating countries enforce emission directives.
Before 1992, the European regulation (directive) standard for automobile emission had been implemented in several stages. In Europe, Euro I (certified emission limits for Euro I) was implemented from 1992, Euro II (certified emission limits for Euro II and production compliance) from 1996, and Euro III (certified emission limits for Euro III and production compliance) from 2000.
