“Hello, please start the vehicle!†After the motor vehicle was launched, the staff of the motor vehicle environmental protection testing center of the Henglong Automobile Vehicle Inspection Station in Changsha County, Hunan Province inserted a special probe into the exhaust gas pipeline of the vehicle to be tested, and sampled the automobile exhaust gas. After a minute, the exhaust gas emission is up to the standard test result.
“Your motor vehicle exhaust gas test is up to standard. Other vehicle tests can be completed.†The staff submitted the test results to the driver. “We used the simple working condition method to simulate the running state of the car to detect the exhaust of the locomotive, and 8 test lines. Each test line can correspond to 100 vehicles per day for vehicle exhaust detection. This is the scene that the reporter saw during an interview with the Henglong Automobile Vehicle Inspection Station in Changsha County on November 25.
"Exhaust gas emitted by motor vehicles contains a variety of pollutants. Because its discharge range is about 1 meter away from the ground, it is easily inhaled by the human body, posing a greater threat to human health." Deputy Director of Changsha Motor Vehicle Exhaust Pollution Monitoring Center Zhong Shinan said that according to estimates, about 25% of the nitrogen oxides in the atmospheric environment of Changsha come from motor vehicle exhaust; and the yellow-label vehicles that account for about 5% of the total number of motor vehicles in the city produce more than 50% of exhaust gas pollution. Therefore, the implementation of environmental protection mark management, strengthen the regular detection of motor vehicle exhaust pollution, the elimination of the yellow standard car is imperative. “Regular inspection is the testing of different types and uses of motor vehicles in a certain period to ensure the safety performance and pollution of motor vehicles before they can drive on the road.†Zhong Shinan introduced, from January 4, 2013, motor vehicle exhaust Since the regular inspection, as of September 30, 2014, the city of Changsha has exhausted exhaust testing of 927,000 vehicles, with a pass rate of approximately 88.2%.
At the same time, the city officially launched the environmental protection signing of motor vehicles on December 1, 2013, and differentiated the emission levels of motor vehicles by issuing green and yellow signs to the low-pollution vehicles that meet the standards and the highly polluting vehicles that meet the standards. The pollution level is subject to differential management in terms of environmental protection periodic inspection and road use rights. “The environmental protection mark is issued free of charge and does not charge any fees.†Zhong Shinan said, “The current elimination of yellow label vehicles is the task of the Changsha Environmental Protection Bureau. The data shows that as of the end of September 2014, Changsha City had eliminated and transferred 13,481 yellow-label vehicles. As of the end of October 2014, a total of 630,000 sets of motor vehicle environmental protection signs were issued.
The reporter learned that in the next three to five years, Changsha will also set up Changsha Motor Vehicle Exhaust Pollution Network Monitoring System, based on the city's motor vehicle basic information center database, including remote monitoring of each test station. The new car and second-hand car are on the environmental protection audit, and the functions of the vehicle owner's inquiries and exposure investigations are included in the system, and every link of daily supervision is included in the system.
