Abstract
A lower ambient temperature leads to a deterioration in some engine characteristics, to a decrease in the durability of parts. Therefore, the main relevance of research work: the design of a heat accumulator by methods of storing thermal energy, the use of heat in the production cycle, the selection of the necessary effective materials and its improvement are relevant. From this point of view, by reducing the cost of operating the unit and preparing engines, an increase in vehicle performance and vehicle engine performance has been achieved. In this work, the amount of heat used by the heat accumulator to heat the engine was determined by the amount of heat consumed by the heat accumulator into the environment, the thermal power released into the environment, the amount of heat consumed by the heat accumulator into the environment when the engine warms up.
