Abstract

The relevance of the study is conditioned by the complexity of ensuring of reliable engine starting in conditions of negative ambient temperatures. In this regard, this article is aimed at identifying the patterns of changes in the conditions of thermal preparation of the engine for starting, depending on the thermal fields of engine elements in contact with the constant thermal pressure of the coolant, and the place where the coolant is removed from the cooling jacket. The main research method was pumping the coolant through the cooling jacket according to various schemes, taking into account changes in the ambient temperature and the volume of the coolant. As a result of the study, the patterns of changes in the thermal fields of engine elements from the pumping circuit were revealed, a regression and calculation equation for the temperature of the engine elements was developed. The materials are of practical value for ensuring reliable engine starting in conditions of negative ambient temperatures.
