S.11 Sustainability & Environmental Technologies Study Group Information Report: RP 1118 Fuel Savings Calculator for Aerodynamic Devices Validation

PIT Group of FPInnovations was approached by The Technology & Maintenance Council of American Trucking Associations (TMC) to validate TMC Recommended Practice RP 1118, Fuel Savings Calculator for Aerodynamic Devices, utilizing the working model of a proposed revision to the original calculator developedin 2018 by TMC’s S.11 Sustainability & Environmental Technologies Study Group. TMC RP 1118, developed and first published in May 2016, provides equipment operators with an interactive mathematical tool to evaluate the potential fuel and economic savings of an aerodynamic device that hasbeen tested using one of TMC’s fuel economy testing procedures. The tool may also be compatible withrolling road wind tunnel testing conducted over a variety of drive cycles. The scope of this RP is limited to Class 6-8 tractors coupled to commercial trailers of all types. The speed range covered is from 40 to 75 mph.
