Methodology for energy savings estimation, resulting from the development of a procedure for air pressure check in vehicle tires

Abstract

The presented paper examines the possibilities of implementation of a methodology for evaluation of the energy savings, as a result of developed procedure for checking the air pressure in vehicle tires. The purpose of the developed methodology is to provide an opportunity to estimate energy consumption after checking the air pressure in the vehicle’s tires. The methodology is based on numerous experimental studies and analytical evaluation of fuel consumption as a function of tire pressure in vehicles. The conditions, the practical procedures and the sequence in the assessment of energy savings, after the introduction of the methodology for checking the air pressure in the tires of road vehicles, are defined. The methodology applies to road vehicles with a maximum mass of up to and over 3.5 tons with a nominal air pressure in the tires according to the manufacturer’s specifications. The data is summarized, based on the type of transport, number of vehicles, purpose of use - personal and business vehicles, tire pressure check, established average fuel consumption (gasoline, diesel and LPG) and average mileage of the study. Finally, a computational example is presented, proving that the methodology gives correct results for the evaluation of energy savings, after checking the air pressure in the tires of the vehicle.
