Passenger Car Fuel Economy in Short Trip Operation. Technical Progress Report,May 1, 1977--November 30, 1977.

摘要

Studies to define fuel utilization in highway transportation have consistently shown that the fuel used in starting and driving the first few miles of any trip is disproportionally large when compared to the fully warmed up fuel economy. The program described was devised to provide a base line for subsequent studies of short-trip fuel economy that will eventually be needed to evaluate alternative power plants and fuels. The immediate objective is the evaluation of methods devised to provide improved fuel utilization and compare conventional gasoline with a special fuel blend aimed at improved short-trip economy. A technical progress report is given that outlines the test design,selection of the fuel blends,driving cycle,operating procedure,test equipment,selection of the test vehicles,and data handling methods. It covers the period May 1, 1977to November 30, 1977. The test work involving the fuel consumption measurements on four vehicles operated on a chassis dynamometer at 0exp 0 F and 90exp 0 F is complete. (ERA citation 03:043238)
