Introduction. The article considers the features of calculating fuel consumption rates for machines and mechanisms. The main methods for determining fuel rates are analyzed, the influence of technical, operational and external factors is taken into account, and the environmental component is considered, in particular, the impact of fuel consumption on the environment and the use of SCR systems to reduce harmful emissions.
The rational use of fuel and energy resources is one of the key tasks in the field of operation of vehicles and road construction equipment. An important role in this process is played by modern methods of assessing fuel consumption and the use of selective catalytic neutralization (SCR) systems, which allow reducing harmful emissions. To achieve maximum fuel efficiency, it is necessary to take into account a wide range of factors that affect the operation of equipment.
Issues. Calculating fuel consumption rates is a complex process due to the variety of factors that influence it. The main problems facing researchers and engineers are the great variability of equipment operating conditions (terrain relief, climatic conditions, soil type, etc.), the dependence of fuel consumption on the technical condition of machines, the control method and the level of process automation, the lack of a universal methodology that takes into account all aspects of the operation of different types of equipment, the need to develop effective algorithms for optimizing fuel consumption.
Purpose. The purpose of the study is to analyze modern approaches to calculating fuel consumption rates, identify key factors affecting fuel consumption, and develop recommendations for optimizing the use of fuel resources in mechanical engineering and the transport sector.
Materials and methods. The article is of a review nature. The article uses a systematic approach, which is a set of general scientific methodological principles (requirements), based on the consideration of objects as systems.
Results. The article considers the issues of calculating fuel consumption rates for road machines and mechanisms as an important stage of planning and optimizing costs in the construction, transport and municipal industries. The need to determine the standard fuel consumption to reduce operating costs and rational use of enterprise resources is substantiated.
Conclusions. The study allowed us to identify the main factors affecting fuel consumption and assess the effectiveness of various methods for calculating fuel consumption standards. It was established that to ensure optimal use of fuel and energy resources, it is necessary to take into account a complex of technical, operational and external parameters. Recommendations have been developed to improve calculation methods, which will increase the efficiency of machines and mechanisms, reduce fuel costs and reduce the environmental impact of vehicles.
