| Popis: | 105 The reason why diesel vehicles are widely applied for transportation is that engines in diesel vehicles are high-powered, oil-efficient, high torque and economic. Diesel vehicles, mainly used as garbage cleaning vehicles in Taiwan, may produce large quantities of grain stored pollutants, leading to deteriorate worsening air quality. The study aims to evaluate the influence on diesel vehicles equipped with soot filters as well as the quantity of air pollutants. To verify the effective of implementing soot filters, test vehicles with soot filters will be placed in the dynamometers to simulate real life driving mode. Examinations on particulate, opaque, levels of smoke and air pollutants are carried out the diesel vehicles equipped with and without soot filter. This research investigated the efficiency of garbage vehicles installed filter smoke device and the benefits of air pullutions reduction. Comparing to the results of installed or without a filter, the average smoke degrees detection was decreased from 9.1% (no load) to approximately 0 % after the filter installed. The Opacity average was decreased from 0.9 m-1 to 0 m-1 and the N.D value could not examine out under the filter condition. In addition, the vehicles speed arere set up at 10 km h-1 and 40 km h-1 showed that the elimination efficiency average of PM10 and PM2.5 were 73% / 76.3% and 76.4% / 79.2%, respectively. Our professional evaluation and recommendations for diesel vehicles to install soot filter will lead to improve the air quality in the near future. The diesel vehicles equipped with soot filters not only provide a significant reduction of black smoke pollutions and feel the pollution reduction results directly and immediately but also hastens the strict idea impetus air quality improvement work. |
