Research on dependence of fuel consumption on cargo weight in long-distance transport
Abstract
Introduction. The current methodology for fuel consumption accounting in road vehicles has not been changed in terms of its quality for a long time. In the majority of transport enterprises of the Cheliabinsk Region, official methods for the regulation of fuel consumption are not used, which indicates the need to improve the fuel consumption accounting standards. The most significant differences between standardized and real consumption are related to transport work.Purpose of the experiment. The article aims to carry out a statistical analysis of the influence of cargo weight on fuel consumption in long-distance transport.Results of the experiment. In order to identify the dependence of cargo weight on fuel consumption in longdistance transport, a study is conducted on the statistical data on the operation of truck tractors at OOO Alliance Auto, one of the largest long-distance road carriers in the Cheliabinsk Region. The study is conducted on MercedesBenz Actros-1840 truck tractors equipped with fuel consumption monitoring devices and devices for determining axle loads. The cargo weigh is determined by subtracting the curb weight from the actual one according to the axle load data. Data on the values of the actual cargo weight and fuel consumption for each trip are recorded using the Fleet Board software and hardware complex; Excel and STATISTICA programs are used to calculate and construct the necessary graphs and regression equations. The statistical analysis performed makes it possible to establish the nature and indicators of the dependence of fuel consumption on cargo weight in long-distance transport. As a result, the relationship between the flow rate and the cargo weight is established; a confidence test is performed; and a regression equation is obtained.Conclusion. Analysis of the collected data shows that the dependence of fuel consumption for transport work by road trains with truck tractors Mercedes-Benz Actros-1840 on the cargo weight for the Russian operating conditions in long-distance transport is linear and amounts to 0.39 liters per 100 km for each ton of transported cargo.
