Economy of hydrogen-fueled automobile engines
Abstract
Considerable reduction in energy consumption is possible for engines using hydrogen fuel, as compared to those using gasoline. Hydrogen engines can be made with high compression ratios, and thus can attain high thermal efficiencies at all loads and speeds. In addition, it is possible to vary hydrogen-air mixture ratios to achieve load control. Lean mixtures at part loads improve thermodynamic performance and reduce pumping losses. For these reasons considerable energy savings are possible, particularly at part loads and lower speeds. The engine used for comparison showed approximately a 20 per cent increase in mileage per unit of energy at 60 miles per hour, and double mileage at 20 miles per hour. These results have been substantiated on an automobile tested at Billings Energy Research Corporation. This economy is possible while creating essentially no atmospheric pollution.
