Development of A Fuel Consumption and Emissions Taxonomy for Nonroad Diesel Equipment

摘要

The purpose of this paper is to present a taxonomy of fuel consumption and pollutant emissions rates for nonroad equipment to assist equipment managers in estimating the energy andenvironmental impacts of their fleets. Diesel fuel is the primary energy source for nonroad diesel equipment. Without it, the equipment is inoperable and non-productive. Estimating fuel requirements can be extremely difficult due to high variability in published fuel consumption rates. Moreover, equipment publications provide no guidance for selecting pollutant emissions rates. The taxonomy is based on real world fuel consumption and emissions data collected from in-use equipment. An engine modal analysis was conducted on the data to categorize it by engine load. Weighted average fuel consumption and pollutant emissions rates were calculated based on the results of the engine modal analysis. The taxonomy presents the weighted average fuel consumption and emissions rates according to equipment type, Environmental Protection Agency engine tier technology type, and pollutant including nitrogen oxides, hydrocarbons, carbon monoxide, carbon dioxide, and particulate matter. The taxonomy provides an accurate and easy to use guide for equipment managers to use in estimating their fuel consumption and resulting pollutant emissions.
