Abstract

The creation of modern high-powered gas and gas-diesel engines is associated with the solution of two main tasks  – the elimination of abnormal combustion and reduction of engine thermal factor. The paper discusses ways to reduce exhaust gas temperatures, methods to eliminate hot-tube ignition and detonation in single fuel gas engines. The ways of reducing exhaust gas temperatures, reducing the thermal factor of diesel injectors (pressure, duration of injection) and detonation issues in two-fuel gas-diesel engines are considered. The results of computational and experimental studies are presented. It is shown that due to the optimization of intake systems, fuel supply and control algorithms it is possible to significantly reduce the thermal stress of gas and gas-diesel engines, while ensuring the achievement of high values of the average effective cycle pressure up to 28 bar and the achievement of high volume power up to 43 kW/l.

Abstract

The article considers the key issues of creation and development of electric transport production in the Republic of Belarus on the basis of domestic developments and advanced foreign technologies. The foreign experience of creating productions and building the market of transport with the electrified power units, as well as decisions and mechanisms of providing the state support to producers and consumers of the transport in the developed countries are analyzed. The defining role of green transport in solving environment pollution problems arising from road traffic is shown. The article discusses the main aspects and prerequisites for the creation of a new sub-sector of the electric vehicle industry for the domestic automotive industry on the basis of the development of design technologies and production of electrified power units, as a key factor in the economic stability of mechanical engineering in the long term. The capacity of science and industry in this field is considered. The paper discusses the targets of the Program of Development of Electric Transport in the Republic of Belarus and provides ways to meet them, including mechanisms and measures to stimulate the development, production and consumption of electric transport at the  state level.
