Abstract

The work highlights the problems of using coolants in vehicles equipped with internal combustion engines, as well as their compatibility with each other. Since the problem of choosing the latter is due to the fact that the range of coolants on the market is extremely wide. Each type contains a certain set of additives that affect its main characteristics: freezing and boiling temperatures, density, etc. And the single color of the coolant does not guarantee that these antifreezes belong to the same group. An analysis of the works of leading domestic and foreign scientists devoted to the problem of choosing and using coolants for internal combustion engines of vehicles was carried out, which showed that the actual problem is the correct selection of coolant for a specific vehicle and the corresponding conditions of its operation. The main factors affecting the use of cooling liquids for internal combustion engines, as well as their compatibility with each other, are highlighted. Recommendations are given for the selection of coolants and their use, the main factor for the selection of coolant for internal combustion engines is the standard according to which the liquid is manufactured. It is not necessary to get attached only to the color, but to select the type - based on the tolerances of the car manufacturer of a specific vehicle. It is shown that there is no clear and unequivocal answer to the question of which antifreeze is better. The fact that lowrid coolants are the best option is obvious, but it is necessary to take into account the requirements of the car manufacturer first of all. The range of coolants on the automotive market of Ukraine is huge. In addition to the fact that each type of liquid contains its own complex of additives, it also differs in its main characteristics: density, boiling and freezing points. Therefore, an obvious answer arises - use only fluids recommended by the car manufacturer.
