TRUCK POWER REQUIREMENTS CAN BE ACCURATELY ESTABLISHED

IN REGULATING MAXIMUM GROSS LOADS OF HEAVY COMMERCIAL VEHICLES, AVERAGE HORSEPOWER AVAILABLE OVER THE ENGINE OPERATING RANGE IS A MORE RELIABLE INDEX THAN INSTANTANEOUS POWER VALUE. AVERAGE HORSEPOWER REFLECTS THE BENEFIT OF INCREASES IN GEAR REDUCTION STEPS, COMPENSATES FOR DIFFERENCES IN HORESPOWER VERSUS ENGINE SPEED CHARACTERISTICS, AND ASSURES REASONABLE LOADED PERFORMANCE OF OVER-THE-ROAD TRUCKS AND TRUCK TRACTORS. EXAMPLES OF THESE ADVANTAGES ARE GIVEN IN THE TEXT AND FIGURES.
