The report investigates vehicle test results from a small twin-roll electric dynamometer. The first objective was to determine the level of equivalency between emissions and fuel economy test results obtained on a hydrokinetic power absorbtion unit dynamometer and on the D.C. motor electric dynamometer and to define any differences between them. The second objective was to quantify, if possible, performance advantages of the electric dynamometer. Specifically, it was to investigate the changes in the measured emissions and fuel economy resulting from changes in the shape of the dynamometer road load force versus velocity curve.
