Along with economic development and industrial society progress, people's income has increased and also improves the quality of life that caused a rapid increase of motor vehicles. Because Taiwan is densely populated, the air quality in urban areas has an important relationship with citizen. According to the result of EPA 2008 Environmental Implementation Intention Survey, improving air quality (29.2%) is that people main hope Government gave priority to strengthen of environmental work in the coming year. Urban emissions of various air pollutants, by 87.8% from mobile sources of pollution, including diesel vehicles emitted black smoke, often leads to bad public impression.
In recent years, due to rapid economic growth, Taoyuan County population has exceeded 1.9 million people so passenger and freight demand tended to increase year by year. The statistics as of 2009 December, Registered in Taoyuan County buses, large trucks and special vehicles up to a total of some 23,229 vehicles, Small truck up to 17,249 cars, there are 535,501 small passenger cars, machinery and bicycles are 1,081,978 vehicles, up to a total of 1,702,386 motor vehicles. Taoyuan County is the third highest number of vehicles registered in Taiwan cities and counties, second only to Taipei County and Taipei City. Urban areas in Taoyuan County, the roads are very intensive and has well-developed bus transportation so there are considerable number of various kinds of diesel vehicles passing, and cause a very serious air pollution. In addition to well-developed industrial area of Taoyuan County, the north is Taipei city and county, the south is the Hsin-chu Science-based Industrial Park. It located within the transportation hub, it has been had large passenger and cargo traffic. On the other hand, since accession to WTO, open up the import of diesel passenger cars in 2004. In the premise that the domestic diesel oil price is relatively cheap, diesel cars are also an increasing trend. Based on a lot of objective conditions, the problem is an overall increase in emissions from diesel vehicles and the public health impact of the county, is more worthy of attention.
This project is mainly detected emissions from diesel vehicles to establish emission factor database, such as PM2.5, PAHs, SO2, NO2, and CO emission factors and conduct perimeter and traffic investigation. Mainly Taoyuan County Environmental Protection Agency will be more aware of the distribution of diesel pollution in Taoyuan County. Mainly Taoyuan County Environmental Protection Agency will be more aware of the distribution of diesel pollution in Taoyuan County, and assist in the elimination of old two-stroke motorcycles and low-pollution vehicles subsidies and grants activities, etc. And use the model simulation and human support to enhance the effectiveness of program implementation.
1. Diesel vehicle emission factor
This project based on the use of three different situations simulated MOBILE6.2, discussing air pollutants from diesel vehicles in Taoyuan County (including HC, CO, NOx, SO2, PM10, PM2.5, and PAHs), etc.
(1) Trucks under 3.5 tons: Emission factor range is between 0.123 ~ 0.339. NOx emission factor is relatively high in Module C (6.811~ 2.857). CO emission factor is relatively high in Module A (3.780 ~ 2.664). PM10, PM2.5 and PAHs are relatively high in Module C.
(2) Short-range passenger car: Emission factor range is between 0.006 ~ 25.0. NOx emission factor is relatively high in Module C (3.67~ 2.644). CO emission factor is relatively high in Module B (12.888~9.112). SO2 emission factor is relatively high in Module C (12.888~9.112). PM10 emission factor In Module C (24.981) is higher than Module A (0.314) and B (0.228). PM10, PM2.5 and PAHs are relatively high in Module C.
(3) Long-haul passenger vans and Tour : Emission factor range is between 0.005~13.0. NOx emission factor is relatively high in Module A (3.470~ 1.199). CO emission factor is relatively high in Module A (9.601~6.703). SO2 emission factor is relatively high in Module C (0.043). PM10, PM2.5 and PAHs are relatively high in Module C.
(4) Trucks over 3.5 tons: Emission factor range is between 0.007~22.0. NOx emission factor is relatively high in Module A (2.806~0.969). CO emission factor is relatively high in Module A (6.869~4.801). SO2 emission factor is relatively high in Module C (0.047). PM10, PM2.5 and PAHs are relatively high in Module C.
(5) Container tractor truck: Emission factor range is between 0.004~71.0. NOx emission factor is relatively high in Module C (8.559~3.469). CO emission factor is relatively high in Module B (9.817~5.170). SO2 emission factor is relatively high in Module C (0.051). PM10, PM2.5 and PAHs are relatively high in Module C.
2. Replace old two-stroke motorcycles by oil and gas dual-fuel vehicles and low-pollution transportations.
※ Replace the old high-polluting two-stroke motorcycle allocated a total of 7,443 cases in 2008.
※ As of 2009, oil and gas dual-fuel vehicles total 488.
※ Supplement the activities of a low-pollution transportation: This year applications for oil and gas bi-fuel cars are 15 cars. Electric bicycles and electric auxiliary bicycles are 200 cars. Bicycles are 56 cars. Oil and gas dual-fuel vehicles can reduce emissions of CO about 0.494 tons / year and HC about 0.01 tons / year. Electric bicycles and electric auxiliary bicycles can reduce emissions of HC about 2.03 tons / year.
※ Other propaganda: Handle six times the media advocacy activities. The establishment of two-stroke motorcycle advocacy site and Taoyuan County to implement the new purchase or modification of oil and gas dual-fuel vehicles operating subsidy program advocacy network.
