What are the standard values for vehicle exhaust emission testing?
1 Answers
Automotive environmental exhaust emission testing standards are as follows: the limit for carbon monoxide is 6.3g/km, and the combined limit for hydrocarbons and nitrogen oxides is 2.0g/km. The general process for vehicle exhaust emission testing is as follows: Information Entry: Computerized entry of information, registration of vehicle details, and allocation of inspection lanes based on vehicle characteristics. This process is fully automated by the computer system. Designated Inspection Lane: The dispatcher will instruct staff to drive the vehicle to the designated inspection lane. Supervisors do not have the authority to change the inspection lane. Lane Confirmation: The control room verifies whether the vehicle has entered the correct inspection lane. Without this confirmation, the next step cannot proceed. Exhaust Emission Testing: This step is performed by the inspector following the prompts on the computer screen. Correct operation is essential for a successful test. The test results are compared against the standard values and then uploaded to the server by the system. Payment: Finally, proceed to the environmental testing fee counter for payment. If the vehicle fails to meet the standards, it must undergo rectification before retesting. Vehicles that pass the test will be issued an environmental certification label.
