Environmental problems today are one of the most important and global indicators of human development. One of the consequences of the impact of agricultural machinery on natural resources is their pollution due to loss of fuel and lubricants and engine waste. The purpose of the research is to develop scientific and methodological bases for the selection of criteria for assessing the environmental safety of the diesel engine of an energy vehicle with the creation of an environmental safety management system. The scientific and methodological basis for assessing these factors is a systematic approach to solving environmental problems that arise during the operation of machine-tractor units and other agricultural energy resources. Estimation of the level of emissions of the main pollutants and toxic substances in exhaust gases can be defined by means of the regulatory characteristic of the engine depending on an operating mode of this engine. The optimal mode of operation of the engine YaMZ-236M2, from an environmental point of view, adopted 1450…1850 rpm. In this case, fuel consumption does not increase in this mode. It is possible to reduce the emissions of the most significant NOx exhaust element by limiting the engine speed to 90% of the nominal. CO and CH emissions at a given engine speed have not reached their maximum value.

The paper presents a technical and economic background to the need for modernization of modern tractors and combines. The presented method allows forecasting the demand for modernization of equipment. It allows to develop the program of action to improve the quality of machines, assess their real potential, develop of strategic and operational planning for the development of modernization, organize activities of the technical service. This article proposes a method for determining the demand for modernization of agricultural machinery in technical, repair and technical enterprises, based on the analysis of statistical and expert data characterizing their influence on the demand for research. It is justified that repair company must confidently organize an active advertising campaign to promote modernized machines to the market.
