N2 - Real-world activity, fuel use, and emissions were measured for three refuse trucks, including one each of heavy-duty diesel front-loader, side-loader, and roll-off configurations in terms of operating mode bins defined by the USEPA for the Motor Vehicle Emissions Simulator (MOVES) emission factor model. CO2, CO, HC, and NO emissions were measured. Fuel use and emission rates between truck configurations and cycles were compared. The side-loader truck had the highest time spent in idle mode while the roll-off truck had the highest time spent in speeds over 25 mph. The roll-off truck has the lowest, and the side-loader truck had the highest, distance based cycle fuel use and emission rates. Comparing duty cycles, the roll-off cycle had a higher proportion of operation in OpModes associated both with higher engine power demand, which led to higher time-based rates, but also with faster travel speed, which led to lower distance-based rates. Compared to real-world, MOVES2010 under-estimated the CO2 emission rates by 20% to 40% and the NOx emissions rates by 40% to 60%. This is an abstract of a paper presented at the 108th AWMA Annual Conference and Exhibition (Raleigh, NC 6/22-25/2015).
