Motor vehicle time and fuel consumption

Paper: Trucks with diesel engines were found to travel about 50 percent more miles on a gallon of fuel than trucks with gasoline engines of approximately equivalent power and gross weight characteristics. Paper 2: During the summer of 1959 the Bureau of Public Roads conducted a study of passenger cars and single-unit trucks to determine the effect of variation of pavement surface type and operating speeds on fuel consumption, and the effect of the elimination of both a stop-and-go and a slowdown operation on fuel and time consumption at various operating speeds. Paper 3: The purpose of this report is to record the procedure and findings of an extensive survey during the summer months of 1959 in which fuel consumption and travel time were measured on nearly every possible classification of truck and trailer combinations, as well as on urban and intercity buses.
