Abstract
A method for determining gross engine horsepower of an internal combustion engine coupled in driving relationship to an alternating current electric alternator, the alternator supplying electric power to variable loads, comprises measuring the field current and average per phase armature current supplied by the alternator; computing the magnitude of electric power supplied by the alternator from the measured values of field current and armature phase current; determining the engine efficiency at the computed magnitude of electric power; and converting the computed electric power to engine horsepower at the determined efficiency.
