Abstract
The average of two horsepower measurements utilizing an empirically-determined horsepower constant, made with electronic diagnostic equipment employing engine transducers, during three successive acceleration bursts from a low engine speed to a high engine speed with the air/fuel ratio regulator defeated so as to provide full fuel, is compared against the average of two additional such horsepower measurements made in three additional acceleration bursts which are underfueled due to feeding the air/fuel regulator with atmospheric air; the horsepower difference is a measure of the action of the air/fuel regulator; one burst of each set simply purges air accumulations in the fuel lines, if any. If desired, indications of horsepower may be calculated without an inertia constant, since the measurements herein are comparative.
