EPA正在开发新一代排放清单模型MOVES（机动车排放模拟器）。模型的第一个版本根据可用的模态数据输出油耗。然而，由于有限的重型车辆的数据，MOVES率需要补充率确定的物理排放率估计（PERE）。PERE将车辆牵引功率与特定于车辆类别的车辆动力系统参数结合在一起;车辆重量、形状、发动机类型和变速器。重型柴油拖拉机拖车车辆，城市公交柴油巴士，和测功机非道路柴油发动机的使用数据的分析，使这些发动机和车辆的柴油发动机效率和摩擦和变速器换档时间表的确定。这些模型参数和模型结果的比较，测量的燃料消耗量和二氧化碳排放量。
The EPA is developing a new generation emissions inventory model, MOVES (Motor Vehicle Emissions Simulator). The first version of the model outputs fuel consumption based on available modal data. However, due to the limited heavy-duty vehicle data, MOVES rates need to be supplemented with rates determined with the Physical Emission Rate Estimator (PERE). PERE combines vehicle tractive power together with vehicle powertrain parameters specific to the class of vehicle; the vehicle weight, shape, engine type, and transmission. Analysis of in-use data for heavy-duty diesel tractortrailer vehicles, city transit diesel buses, and dynamometer non-road diesel engines has enabled a determination of diesel engine efficiency and friction and transmission shift schedules for these engines and vehicles. These model parameters and a comparison of the model results to measured fuel consumption and CO2 emissions are presented.
