Mobile pollution sources are one of the main reasons for the deterioration of air quality in urban areas, and they are also the focus of environmental protection and transportation authorities to strengthen control. Among them, the black smoke emitted by diesel vehicles is the most criticized by the public. In order to effectively control diesel vehicles, this plan not only continuously strengthens inspections and inspections, including roadside inspections/block inspections, station inspections, visual smoke detection inspections, and inspections and controls for parking, idling, and flameout inspections, but also through special control and education. The correct concept of vehicle maintenance and inspection has achieved the effect and purpose of pollution reduction. The relevant achievements of this year are summarized as follows:
All quantitative targets for this year have achieved an overall progress of more than 100% in accordance with the contract, and the relevant implementation results are shown in Tables 1-3. The city’s diesel vehicle dynamometer inspection station is undergoing station repairs and equipment renewal operations, so there is no dynamometer inspection operation. In order to improve the city’s diesel vehicle acceptance rate and reduce its pollution emissions, the team implements ① Roadside inspection, A total of 5,348 vehicle-times were inspected by visual inspection, station inspection, and in-field inspection of large households in the city. ②A total of 18,462 vehicle-time inspections were carried out on license plate recognition. Vehicles that have not been inspected within one year are screened and managed by the city Vehicles with overdue stamps voluntarily sent inspection notices, and a total of 500 notifications were sent. ③ Random sampling and screening of 348 illegal oil product control cases, of which 12 were sent for inspection for sulfur content analysis.
In addition, 341 inspections of parking, idling, and flameout were carried out, and 1 maintenance workshop publicity briefing was held, the household administration system maintenance server web page and connection system version update, general environment and road traffic monitoring 40 points, and non-ionizing radiation monitoring and data Upload homework 40 times.
In terms of promoting the self-management plan, a total of 1,109 self-management labels were issued this year, and we worked with Hsinchu County to promote CSR (Corporate Social Responsibility) for industry players in the Hsinchu Science Park, and used low-pollution vehicles (either the company itself or outsourced manufacturers) Diesel vehicles must use Phase IV or above (inclusive), Phase III vehicles are equipped with air pollution control equipment or Phase III vehicles are not equipped with air pollution control equipment, but the inspection meets the standards of Phase IV), 366 companies submitted information this year, After screening, a total of 1,105 diesel vehicles from 244 companies are eligible for promotion. The reason for non-compliant companies is that they use vehicles that are not within the signed specifications. We will continue to track the use of diesel vehicles that meet the requirements of the company. It is scheduled to announce the results in December and issue certificates and release press releases .
In the part of promoting maintenance factory certification, we will continue to improve the inspection quality of existing maintenance factories and guide B-level maintenance factories to upgrade to A-level. The city authorized Changyuan Automobile, Hsinchu Passenger Transport and Yongfeng Injector Co., Ltd. to issue self-management marks certification and maintenance factories. A total of 734 self-management marks were issued. The inspection load during the repair period of the moving station, in order to ensure the quality of inspection, our team sends personnel to 3 certified maintenance factories for inspection every month. Except for Yongfeng injectors that have wrong car number planting points, Changyuan Automobile and Hsinchu Passenger Transport None are missing. In addition, in this year, a new B-level maintenance factory was added to assist Zhongxing Diesel Bangpu Enterprise Co., Ltd., which is approved by the Environmental Protection Agency to accept the subsidy maintenance factory for the repair of fuel control systems for large diesel vehicles. It already has 1 opacity meter equipment and 2 people. We have a diesel vehicle inspection certificate, so since January, our team has been going to the maintenance factory for instrument comparison operations every month to confirm the maintenance ability and quality verification. On October 3, it passed the on-site evaluation of 2 committee members and upgraded to A-level certification maintenance plant.
This year, through station inspections and roadside inspections, for vehicles equipped with SCR prevention equipment, the crystallization of urea barrels was confirmed one by one, and the concentration of urea was confirmed with a hydrometer. A total of 122 vehicles were inspected, and the average urea concentration was about 32.1%. At the same time, it is the first in the country to jointly inspect vehicles equipped with SCR prevention equipment with authorized certified maintenance factories. A total of 36 vehicles were inspected. The average urea concentration was about 32.1%, which was close to the standard concentration of 32.5%. No abnormal vehicles were found. In addition, in order to grasp the consumption of urea, a letter was sent on March 18, 2011 to investigate the use of urea-using vehicle fleets in China Petroleum and its jurisdiction. The statistics increased from 500,000 liters sold every half year in 2010 to June 111 every half year. Sales of 620,000 liters have increased the consumption, showing that the sales volume of urea has increased year by year, and there is no abnormal situation.
Integrating the above control measures, the number of old vehicles is 271, and the reduction of each pollutant is 8.39 metric tons/year for PM10; 7.16 metric tons/year for PM2.5; and 168.07 metric tons/year for NOx.
