STRETCHING THE GASOLINE GALLON. AN ENGINEERING APPROACH

The author considers various methods of reducing energy use in transportation by reducing energy demand per vehicle mile. Possible engine improvements and alternatives discussed are redesign of carburetors and variation in fuel mixtures, and alternative power plants such as the stratified charge engine, the Wankel rotary engine, the gas turbine (Brayton cycle), Rankine cycle (steam), and Stirling engines. The advantages and disadvantages associated with these engines are presented. Improvements in fuel economy as a result of reduced vehicle size and weight are considered, as are the necessity for maintenance or improvement of present safety standards. Suggestions are given for other design improvements such as modified body design to reduce aerodynamic drag and improved tire design to decrease rolling resistance.
