Developing emission inventory for nonroad mobile equipments is the initiating step of nonroad mobile source emission control. NONROAD model developed by U. S. EPA was studied, and methods based on actual fuel consumption rate were established to calculate fuel consumption and emission inventory of excavators and loaders in China. Surveys were conducted on key emission parameters of typical construction equipments in China, including equipment inventory, annual activity, actual fuel consumption rate, and emission factor. Results show that diesel consumption of excavators and loaders was 1.21 x 10(7) t, accounting for 9.7% of total consumption of all sectors in China in 2007. Total emissions of NO, and PM from excavators and loaders were 6.81 x 10(5) t and 5.31 x 10(4) t, respectively. The data indicates construction equipments are important emission sources compared with motor vehicles. According to the results, it is necessary to tighten limits of exhaust pollutants for construction equipments in China and to bring them into effect.
制定非道路移动设备排放清单是控制非道路移动源排放的起始步骤。对美国环保署开发的NONROAD模型进行了研究，并建立了基于实际燃油消耗率的方法来计算中国挖掘机和装载机的燃油消耗及排放清单。对中国典型施工设备的关键排放参数进行了调查，包括设备保有量、年活动量、实际燃油消耗率和排放因子。结果表明，2007年挖掘机和装载机的柴油消耗量为1.21×10⁷吨，占中国所有行业总消耗量的9.7%。挖掘机和装载机的氮氧化物和颗粒物总排放量分别为6.81×10⁵吨和5.31×10⁴吨。数据表明，与机动车相比，施工设备是重要的排放源。根据研究结果，有必要收紧中国施工设备的废气污染物限值并使其生效。
