Correlation Between Effective-Equivalent Kilometres and Average Fuel - Lubricant Consumption of Road Motor Vehicles: Correction Coefficients and their Application

The monitoring of the standardised consumption of motor fuels and lubricants for each car and driver is obligatory for all units having their own fleet of road vehicles. In order to comply with the standardised consumption of motor fuels and lubricants, it is necessary to continuously monitor them at all levels and to deal with any deviations of any kind that lead to excessive consumption with the maximum exigency. The scientific paper presents in a concrete and elegant way a point of view of the authors, presented with the aim of highlighting the documents and devices that manage the effective, real kilometres travelled, but also the correlation between the effective-equivalent kilometres travelled and the average fuel - lubricant consumption of road vehicles. The most important correction coefficients (surcharges) are presented here, and in the case study we provide concrete, relevant examples of how the mathematical calculation of fuel consumption for passenger cars, trucks, lorries, special car and crawler construction machines. At the end of the scientific article, the conclusions in the field are presented.
