According to the analysis of the air quality model of the Environmental Protection Department, in addition to the impact of overseas transmission, the impact ratios of domestic mobile sources, industrial sources and other fixed sources on fine aerosol concentration (PM2.5) are 30%~37% and 27%, respectively. 31% and 32%~43%, of which diesel diesel trucks accounted for the highest 11.2%~16.8%. In order to reduce the pollution emissions of diesel trucks and improve air quality, the Environmental Protection Agency announced the subsidy for the Republic of China in June, 88. The old large-scale diesel vehicles that were ex-factory before the 30th (hereinafter referred to as the first 1-2) and the large-scale subsidies of the Republic of China from July 1, 1998 to December 31, 1995 (hereinafter referred to as the third period) Diesel vehicles are equipped with filter filters to maintain national health and living environment. To enhance the pollution control of used diesel vehicles in use, the EPD announced on August 8, 2006 and August 16 of the same year the implementation of the third phase of the installation of the filter and the removal of the first and second phase of the large diesel vehicles. The subsidy method is to increase the willingness of the relevant car owners who are eligible for the subsidy to apply for the removal and installation of the filter, and thus reduce the pollution caused by the old diesel vehicles.
