Diesel engines are widely used in the transportation of passengers or goods, construction machinery, etc. because of their high output horsepower and low fuel consumption compared with gasoline engines. The rapid economic growth has drastically increased the use of diesel vehicles. However, studies have shown that black smoke pollutants emitted by diesel vehicles have a serious impact on human health. Therefore, in addition to testing and inspecting diesel vehicles irregularly, this plan tightens the regulation of vehicles in use. For instance, subsidies are available to the replacement of phases 1 to 3 large diesel vehicles, adjustments and repairs on fuel control systems, or the installation of air pollution control equipment. Enterprises are encouraged to sign the use of phases 4 and 5 eco-friendly vehicles. Government agencies promote the self-monitoring mark of diesel vehicles and authorize certified proxy maintenance plants to verify and issue the self-monitoring mark to reduce diesel vehicle pollution.
To cooperate with the Department of Environmental Protection, Taoyuan to implement the diesel vehicle control strategy and achieve the goal of the Air Pollution Control Act, this plan not only assists the Department of Environmental Protection in detecting diesel vehicles that emit black smoke, but also provides vehicle owners with exhaust inspection. Moreover, this plan guides vehicle owners in acquiring the self-monitoring mark issued by the Environmental Protection Administration, Executive Yuan. Regular maintenance and regular testing aim to reduce diesel vehicle pollution.Cooperating with the Environmental Protection Administration, Executive Yuan to promote the policy of subsidies for the replacement of old large diesel vehicles, adjustments and repairs on fuel control systems, or the installation of air pollution control equipment, this plan supports the review, verification and subsidy appropriation of subsidy applications, and organizes relevant promotional briefings to achieve the objectives set by the Environmental Protection Administration.
The results of executing the plan from January 1, 2020 to December 31, 2020 were as follows:
1.In accordance with the Method and Procedure for Testing Opacity of Black Smoke Emissions from Diesel Vehicles promulgated by the Environmental Protection Administration, 2,871 vehicles were tested by the dynamometer. 51 vehicles were rejected due to insufficient weight-horsepower ratio, and 257 vehicles failed. The failure rate was 9.1%.
2.Four certified proxy maintenance plants in Taoyuan were authorized to verify and issue the self-monitoring mark to 1,586 diesel vehicles.
3.The classification control of urban buses was promoted. There were 1,934 buses operated by 14 companies, and 1,589 vehicles were in compliance with the self-monitoring mark. The compliance rate was 82.2%.
4.The notification of voluntary testing was sent to 22,000 vehicles. Among them, 2,629 arrived to be tested, and 233 failed. The failure rate was 8.9%.
5.Among the phases 1 to 3 old large diesel vehicles, 873 were replaced, with a subsidy of 313.965 million dollars.
6.Among the phases 1 to 3 large diesel vehicles, 175 underwent adjustments and repairs on the fuel control systems, and 4 installed the air pollution control equipment. The subsidies amounted to 10,468,100 dollars.
7.The license plate recognition system was maintained for normal operation at six sites, Vehicles that had no test records in the most rent year were singled out, and the notification of voluntary testing was sent to 4,896 vehicles.
