Statistical evaluation of fuel consumption of buses with specific operational changes

Energy, 1991, vol. 16, issue 10, 1225-1230

Abstract: We present the results of a statistical study on the effects of the following four operational changes on the fuel consumption of scheduled buses: a change in the brand of engine oil used, a switch from crossply to radial tires, engine overhaul, and vehicle maintenance. This is an empirical study using data collected with vehicles in normal operations. The technique of inferential statistics was used to make conclusions on whether significant fuel savings were realized. The results obtained reveal the differences between vehicle performance before and after the specified operational changes and provide useful information for reducing vehicle operating costs.
