Abstract

Dynamics of scientific and technological progress are such that the modern world economy features excessively high rates of mineral extraction, which outpace the processes of natural renewal. Depletion affects on geopolitical conditions. Nowadays, the arctic area is one of a few areas in the world that contain huge mineral resources. A number of states lay claims on transpolar territories. The true interest to exploration the Arctic is based on set of strategic and economic grounds. Protection and ensuring national interests of Russia is provided by the Presidential Decree No. 645 “On strategy of development of the Arctic Zone of the Russian Federation and ensuring national security for the period up to 2035” dated October 26, 2020. Main feature of transarctic regions is negative air temperature. The latter negatively influences on working processes of piston engines, processes of phase state change of liquid fuel at air-fuel mix preparation, hinders working body homogenization and successful start. Therefore, heat preparation is needed. The existent methods of heat preparation of on-ground vehicles engines have unreasonable high energy and labor consumption. The modern science proposes new technology in solving the issues of heat preparation based on accumulation, storage and deploying heat energy produced by an engine during application.

The purpose of this review is to provide a comprehensive presentation of new solutions in field of heat preparation of engines, as well as solutions aimed at increasing the energy efficiency and adaptability of ground vehicles for use in Arctic conditions.

The described features of a heat accumulator present fundamental knowledge and give the direction to new

The induction-type phase transition heat accumulator, related to the group of highly efficient buffer systems for heat storage and deployment within the heat preparation, is noteworthy for design engineers, developers of basic internal combustion engines aimed to cold climate conditions with negative temperatures.
