It is estimated nearly 80,000 construction engineering machines (referred to as construction machines hereafter) in Taiwan. To improve the pollutant emission of construction machines and considering that proper maintenance of these machines helps improve exhaust emissions, the self-management label for construction machines is developed and promoted. A self-management label is issued to construction machines that comply with the opacity rate of 1.0 m-1 or lower as determined by environmental protection authority with instrument or are visually determined without the concern of pollution. The public construction projects and construction businesses are the priorities of encouragement. It is focused on improvement consultation for construction machines of high pollutant emission; i.e., the machine owners are encouraged to replace with new machines, install air pollution control or modify fuel control system in their machines, as an effort of pollution improvement. On the other hand, seeing the lack of domestic information in terms of pollutant emissions by construction machines, this program employs the Portable Emission Measurement System (PEMS) for field tests on these machines to establish domestic emission factors of construction machines and develop the trends of pollutant emission by various operation patterns for the basis of identifying the characteristics of air pollutant emissions by construction machines in Taiwan.Also, we have sampled and tested a total of 60 set of gasoline, 60 set of diesel, 10 set of aviation fuel and 10 set of ships fuel. All the samples met the “Amendment to the Standards for the Composition of Mobile pollution source Fuels”. Consolidated domestic and foreign oil product control regulations and related materials for the promotion of alternative fuels, and collected the impact of the refining process on the components of gasoline and diesel, the current status and trends of alternatives such as alcohol gasoline and biodiesel at home and abroad. Consolidated and analyzed the mobile pollution source oil inspection data from the Environmental Protection Bureau. The information above is used as a follow-up mobile pollution source air pollution improvement policy research and development.
