With regarding to diesel vehicle contamination control, in order to improve the air quality and provide a clean and fresh living environment to the folks in Hsinchu county, Hsinchu County Government Environmental Protection Bureau has entrusted to perform Inspection Plan of Diesel Vehicle Dynamometer In Smoke Exhaust Detection Station at regular interval, hoping to effectively improve the air quality condition, to reduce the pollution and to achieve environmental protection in Hsinchu county through the aperiodic inspection control. This plan mainly focuses on inspecting the diesel vehicles that driving in Hsinchu county. With the methods like public report and visual smoke exhaust detection, inform diesel vehicles that driving in the jurisdiction to the station for inspection; and for the spot inspection of oil quality, it will be performed by collecting the oil in the station and inspecting on the roadside and passenger station to control the illegal oil with higher sulfur content.
