IMPROVED FUEL ECONOMY FOR AUTOMOBILES

This article describes several measures that offer the potential for improving the fuel economy of all sizes of cars. All of the measures are possible with current technology. Some of the measures would increase automobile prices, but this is considered justifiable as fuel becomes more scarce. The measures described are the following: varying the compression ratio of the ic engine; improving carburetion; improving the ignition system; reducing internal mechanical friction; recovery of pumping losses; improving the warmup process; eliminating idle; combining the virtues of the automatic and manual transmissions; changes in the rear axle system; redesign of tires for low rolling resistance; re-examination of absorption refrigeration for air conditioning and improvements in present air conditioning systems; designing cars for a performance capacity according to the power demand required and not that simply desired; and styling cars for less air resistance. In conclusion it is pointed out that a government-sponsored research program, completely independent of the auto industry, is needed to explore and evaluate these various approaches. Upon completion of such a program, the most expeditious way of applying the standards developed is seen as the imposition of specifications by the General Services Administration on automobiles for government purchase.
