As the horsepower outputted by diesel engines are higher than oil engines, the oil consumption of diesel engines are also less than that of oil engines. Thus, diesel engines are comprehensively applied to the transportation of passengers, cargoes, construction machines or other purposes. As the swift growth of economy, the quantity of diesel vehicles also increases accordingly in a short time. However, many researches show that the pollutants exhausted by diesel vehicles will result in serious damages to human bodies. Therefore, regarding the pollution control of diesel vehicles, it is necessary to gradually make the emission standards stricter in new vehicle models; besides, it is also necessary to more strictly manage and control the emission of vehicles currently in use and promote the vehicle owners to maintain their vehicles on time and periodically inspect their vehicles in order to avoid that their vehicles become the pollutant sources. So as to cooperate with the control strategy of Environmental Protection Bureau for diesel vehicles and achieve the object of “Air Pollution Protection Act”, the major measures of the project are to conduct the diesel vehicle dynamometer inspection and the station test inspection to irregularly inspect, maintain and improve the diesel vehicles currently in use so as to effectively improve the air pollution of Taoyuan City and realize the environmental protection.
