Evaluation of the Uncertainty in Constant Speed Fuel Consumption Test

Abstract:

With the growth of vehicle ownership, a great quantity of yearly oil import is necessary in China. Because of the energy shortage, people are forced to pay more and more attention to the automobile fuel economy, and government and automotive manufactories are forced to pursue the ways to reduce the vehicle fuel consumption. As the fuel economy has to be evaluated by the measurement of fuel consumption test, the accuracies of these tests are also attracted more and more attention. In this paper, various factors influencing the constant speed fuel consumption are analyzed. Furthermore, a feasible evaluation method of the measurement uncertainty is proposed, and the expanded uncertainty of the test results is calculated using this method.
