Abstract:

A technical solution has been proposed to reduce the consumption of basic hydrocarbon fuel, to improve the technical, economic and environmental performance of internal combustion engines by affecting the combustion process of the fuel-air mixture with a minimum effective mass fraction of hydrogen additive in the fuel-air mixture. The burning rate of hydrogen-air mixtures is an order of magnitude greater than the burning rate of similar mixtures based on gasoline or diesel fuel, compared with the former, they are favorably distinguished by their greater detonation stability.

Abstract:

The methods of increasing the efficiency of internal combustion engines through heat utilization are examined. A proposed classification of heat utilization systems for mobile energy vehicles is presented. External utilization harnesses the heat generated by a diesel engine to fulfill the needs of consumers not directly related to the engine, such as interior heating and air conditioning systems. Internal recycling focuses on enhancing the power, environmental performance, and economic performance of an engine and its related systems. Various heat utilization schemes are compared.

The Power Sector is undergoing a rapid technological change with respect to implementation of low carbon technologies. The IEA Energy Outlook 2017 shows that the investments in Renewables for the first time are equal to those on the fossil sources. It is likely that the conventional gas turbines and internal combustion engines will need to be integrated in systems employing biofuels and/or CCUS (Carbon Capture Usage and Storage). Also, the European Union is moving rapidly towards low carbon technologies (i.e. Energy Efficiency, Smart Grids, Renewables and CCUS), see the Energy Union Strategy.

This thus motivates automotive industries and researchers to investigate tribological performance of internal combustion engines. Piston secondary motion has prime importance in internal combustion engines and occurs due to unbalanced forces and moments in a plane normal to t

This article describes methods of development of technical diagnostic systems for internal combustion engines. The automotive industry plays a leading role in the economy of any state. The history of the development of the global automotive industry is closely linked with the development of many branches of engineering. So, by the beginning of the 20th century, the automobile industry began to consume half of the steel and iron produced, three-quarters of rubber and leather, a third part of nickel and aluminum, and a seventh part of wood and copper. Autobuilding came in first place in terms of

Petroleum has been used as the power source for internal combustion engines for hundreds of years. Nowadays, the problems of fossil energy shortage and environmental pollution are becoming increasingly serious. In response to China's carbon neutrality strategy, it is urgent to seek alternative fuels that can replace petroleum as the power source of internal combustion engines. The challenges of alternative fuels include reducing post-combustion pollutant emissions and being able to recycle them while maintaining the original engine performance. Using hydrogen as fuel can reduce automobile exha

This paper explores the performance differences between traditional internal combustion engines (ICEs) and hybrid engines. Traditional ICEs have been the cornerstone of automotive technology for over a century, operating by converting chemical energy from burning fuel into mechanical energy. Despite their widespread use, traditional ICEs are significant contributors to air pollution and global warming. In contrast, hybrid engines combine one or more electric motors with a traditional ICE, utilizing battery packs and regenerative braking to enhance fuel efficiency and reduce emissions. As socie

Abstract:

Although the lubrication systems for internal combustion engines have been designed to prevent engine wear and friction, their configuration does not contemplate the maximum use of each load of lubricant; because of this limitation, lubricant consumption is currently an environmental and economic problem. In this work, the performance of lubrication systems to form the tribological film that prevents wear is simulated and optimized, through the mass balance of the lubricant precursors contained in the oil and the implementation of optimal control techniques.
