    Abstract

    Heavy duty diesel construction equipment consumes large quantities of fuel and subsequently emits significant quantities of air pollutants. This paper presents a methodology for characterizing fuel use and emissions rates of construction equipment in order to better estimate air pollution emission rates. The research is based on real-world data collected ftom the equipment as it performed construction activities in tlre fleld. This study examined five wheel loaders by estimating the weighted-average fuel use and emissions rates via an engine load modal analysis. For each wheel loader, the engine load data was classified into 10 modes, ranging from the minimum to the maximum engine load, and an average fuel use and emissions rates were determined for each mode. The overall weighted-average fuel use rate was determined by multiplying the modal average fuel use and emissions rates by the percentage of time spent in that particular engine mode and then summing the results for each of the 10 modes. Monte Carlo simulation was used to model the distributions of the weighted-average fuel use rate for each wheel loader by randomly selecting values (within specified ranges) for the percentage of time spent in each engine mode and the modal average fuel use rate. The resutts indicate that there is inter-vehicle variability in the weighted-average fuel use rates of the five wheel loaders. A sensitivity analysis was also performed in order to determine which variables have the greatest impact on thg wqighted-averagg fuel use and emissions rates.
