The object of this study is the field of patenting of technological advances registered in the world in the field of automotive power plants. The subject of the study is the dynamics of patenting in the automotive power plant industry, associated with the need to harmonize the trajectories of technological development with global trends in energy efficiency and manufacturability, in order to ensure sustainable economic growth. Patenting in the industry is considered in the following areas: gasoline engines, diesel engines, hybrid cars, electric cars, hydrogen cars. The relevance of this study is determined by the general desire of society to innovate through the latest tools and the introduction of systemic measures to comprehensively address the problem of increasing energy efficiency and reducing air pollution caused by road transport. The paper analyzes the statistics of patents registered in the world, examines patent activity and trends in the patenting of technological advances in the automotive industry from 2010 to 2022. In the industry of gasoline and diesel engines, hybrid vehicles, electric vehicles and hydrogen vehicles, the current work investigates through systematization and analysis of important aspects of patenting statistics and innovation dynamics. For the period of 2017–2022, the average increase in the number of registered patents per year compared to the previous period was found to be 1.37 times higher for the area of "hybrid vehicles", 1.3 times higher for the area of "electric vehicles", and 26 times higher for the area of "hydrogen vehicles". A comparative analysis of the number of registered patents by areas was carried out, further patenting rates were predicted, and priority areas of research and innovation were identified

“…At present, the increase in the technological flexibility of the layouts of the considered group of machine tools is largely based on the new direction of using integrated assemblies, called mechatronic ones. These units are characterized by the fact that the motion module (linear and/or rotational) is made based on special brushless motors or electric machines with electromagnetic or electromechanical reduction, equipped with sensor systems, measuring transducers, and other electronic elements integrated into electromechanical units [15, 16,17] which, among other things, aim to achieve positive effects in the load -contact -friction -wear chain [18]. Mechatronic modules and mechatronic units [19,20] are the most promising basis for creating relatively flexible progressive high-performance technological equipment, one of the principles of construction of which is the autonomy of manufacturing, assembly, and debugging of autonomous modules and, at the end, of the entire machine, arranged on their basis.…”

The article analyses a wide range of existing technological systems for machining engineering production from special aggregate machines with rigid kinematic connection (control system) to portable machines with mechanisms of parallel structure, which are based on the aggregate-modular principle of the layout. The advantages and disadvantages of such equipment in the modern conditions of manufacturing development are considered in terms of their life cycle in the supply chain and the prospects for further implementation in the machine tool market. The authors analyze the contradictions between the performance and technological flexibility of machining systems and propose ways of resolving these contradictions on the basis of scientific achievements in the field of components, mechatronics, and CALS technologies. On the basis of the performed analysis, the authors suggest a concept and partially implemented a technique for creating various purpose machine-tool systems based on unified technological mechatronic modules considering the tendencies of modern machine-tool production to ensure the sustainability of enterprises under conditions of rapidly changing demand. The prospects of using augmented reality (AG) manufacturing tools for passportization of equipment and its components in order to optimize and green the life cycle of metal-cutting equipment have been substantiated.

“…In addition, new models and methods of researching the processes and states of structural elements with various methods of strengthening are also needed [18,19]. However, emphasis is made in [18] only on the advantages of discrete strengthening. On the contrary, in [19,20], the authors argue about the advantages of continuous strengthening.…”

One of the most rational methods of energy utilization of compressed gas in pipelines is to use turbo-expander installations. In particular, these are autonomous turbo-expander power stations. A fundamentally new concept has been devised to improve the technical and economic performance of this type of machines. This concept is not focused on a separate aspect of the plant's operation but on their entire set. In particular, physical principles, structures, and technologies were considered as an object of research. First, effective parameters of gas-dynamic flows and heat-mass transfer were determined based on the modeling of work processes. Secondly, progressive designs of turbo-expander units have been created. Thirdly, technologies for the production of parts and assemblies of turbo-expander units have been developed, which combine, unlike the traditional ones, different types of strengthening for contacting parts in their pair. A method of parametric modeling was used to substantiate the technical solutions of the elements of turbo-expander power plants. This makes it possible to determine the technical characteristics of these installations under a certain set of parameters. By purposeful variation, a recommended set of their parameters was determined, which ensure the improvement of the most important technical characteristics. A specialized database was built, which contains an array of information about the regularities of the influence of variation of significant parameters on various characteristics of turbo-expander power plants. Already on this basis, the problems of synthesis of successful technical solutions of turbo-expander power plants are solved. As a result, their high energy efficiency is ensured. Thus, the efficiency of the expander was achieved at the level of 86 % while the resource increased by 20–25 %. All these solutions were implemented in a number of unique turbo-expander units. Their effectiveness has been demonstrated during operation
