Horsepower computing network for chassis dynamometers

摘要

A vehicle chassis dynamometer for measuring available vehicle road horsepower is disclosed together with means for compensating an apparent dynamometer horsepower reading for dynamometer vehicle rolling resistance, and vehicle drive line losses, and adjusting for ambient barometric pressure, temperature, and fuel specific gravity to obtain an accurate reading of engine flywheel horsepower that may be used directly for comparison with engine manufactures SAE rated horsepower.
