Assessment of the influence of air temperature and cargo weight on fuel consumption and emissions of harmful substances with vehicle exhaust gases

Abstract

Changes in the operating conditions of vehicles have a significant impact on their technical parameters, including fuel consumption and emissions of harmful substances with exhaust gases. When transporting by vehicle in low air temperatures, the weight of the transported cargo also has a significant effect on fuel consumption. A change in fuel consumption will lead to a change in the amount of harmful substances and exhaust gas emissions. The existing regulatory documentation in the field of road transport operation does not take into account the degree of change, and, accordingly, the influence of such factors as the ambient temperature and the transported cargo weight. The paper describes a developed method for assessing the effect of air temperature and cargo weight on fuel consumption and the release of harmful substances with exhaust gases. The method includes the use of the developed coefficients. Taking into account the degree of influence of each of these factors will improve the efficiency of the application of regulatory documents, will give a more objective approach to assessing the perfection of the designs of cars of different brands and models when comparing them, as well as charging fees for the burned fuel and emitted harmful substances with vehicle exhaust gases.
