Concern about the EPA fuel econymy measurements has focused greater attention an the dynamometer and the dynamometer adjustment. Specifically, the alternate procedures for determining the dynamometer power absorption to simulate the vehicle road experience affords an opportunity for both greater precision and possible abuse. Because of the possibility for abuse, it was decided to occasionally check the appropriateness of the alternate dynamometer power absorptions requested by vehicle manufacturers. The question of the representativeness of the requested dynamometer power absorption for the Ford LTD was first raised during the summer of 1977. This report collects and summarizes the pertinant available data which habe been generated by the EPA Emission Control Technology Division, the EPA Certification Division, and by Ford Motor Company.
