With the purpose of transition of the world economy to a sustainable growth model, the principles of the "green" economy should be integrated into the currently implemented structural reforms. The four main directions that form the "green" economy are highlighted. Structural reform, which connected with directions, can serve as engines of economic growth. Particular attention in passing to the green economy is given to the formation of modern infrastructure, which has the key to ensuring sustainable development and modernization that is an important element of the structural reforms analyzed here. Worldwide, initiatives are emerging at the national level that show that countries are moving towards a "green" economy at their own pace and in the context of their national development goals and priorities. Most countries in the world have recently stepped up their environmental policies to move away from a traditional model in which environmental protection is considered a burden on the economy, to a model in which ecology is recognized as the engine of development, i.e. to the "green" economy.

Combustion engines operate over a wide range of power and speed. To the greatest extent, this applies to automotive and tractor engines and diesel engines operating at fractional and idle loads for a significant part of the operating time. When designing engines, the choice of their main design and layout parameters is carried out in a comprehensive manner, taking into account the provision of the required power and efficiency in the modes of maximum torque and rated power. However, ensuring the economical operation of modern highly accelerated diesel engines at low loads and idling causes a whole range of problems related mainly to the organization of effective mixture formation and fuel burnout, as well as to ensuring stable fuel supply. Thus, the cycle dose of injected fuel in idle mode is 8–12 times less than the cycle dose in nominal mode, which determines increased requirements for fuel equipment and difficulties in ensuring high-quality mixture formation. At the same time, diesel engines operate in idle mode up to 50 % of the total operating time, consuming up to 15–20% of the fuel. For truck engines, the relative idle time is approximately 20–25 %. Thus, the development of measures to improve the efficiency of diesel engines at idle is relevant. The purpose is to perform a numerical analysis of the effect of switching off cycles in diesel engines for autotractor and diesel locomotive purposes on the working processes in the cylinder and the indicator parameters of the cycle in idle modes. When writing the article, traditional methods (comparison, description, and measurement), generallogical methods and research techniques (analysis, generalization, etc.) were used. A numerical analysis of the operating cycle of a diesel engine equipped with a cycle shutdown system was performed. The relationship between changes in fuel injection characteristics when cycles are turned off with indicator indicators of the engine operating cycle in idle load modes is disclosed. It has been established that the expediency of switching off cycles in a specific engine operation mode is determined primarily by the features of the injection, carburetion and fuel burnout processes.

An analysis of the mechanical, chemical and pyrogenic impact of the Baikonur Cosmodrome on the environment showed the presence of man-made impacts of the first stages (FS) used on the ecosystems of the impact zones (IZ). This article presents the concept of a controlled landing of spent launch vehicles with liquid rocket engines (LRE) in the expected zones of damage to the ecosystems of the area while maintaining the energy-optimal launch scenario of the launch vehicle. Purpose of the article - development of effective technologies for reducing the anthropogenic impact during launches of promising rockets from the Baikonur Cosmodrome based on theoretical and experimental studies of innovative technologies: reducing the area of impact of parts from launch vehicles; fire and explosion safety, no danger of rocket launchers; controlled descent of used first stages; To solve the problem, it is proposed to create an additional IASM, which will be included in the environmental management system of the Baikonur Cosmodrome. Possible design solutions are proposed based on the evaporation of untreated liquid waste from the tanks of separated parts, their fire and explosion safety, and the use of the obtained vapor-gas mixtures for controlled unloading of separated parts while moving along the landing trajectory to the optimal area. The authors of the article have developed evaluation criteria that characterize the main environmental indicators of the studied areas: fire hazard, soil cover and impact on vegetation are studied for inclusion in the IASM. There are objective requirements and basic rules for the creation of HIASM, which is an integral part of the environmental management system of the cosmodrome.
