PERATIONAL MONITORING OF TEMPERATURE CONDITIONS OF RESOURCE-SIGNIFICANT AGGREGATES ON AUTOMOTIVE EQUIPMENT

When operating automotive equipment at low or high ambient temperatures, various devices are required to maintain the thermal regime of the units in the permissible range, which significantly affect the internal energy consumption and the service life of the machine. Currently, such a complex thermal preparation is implemented only for the engine by heating or cooling the coolant. For other systems and units, continuous monitoring of their temperature is not provided, and there are no rules or clear requirements for the implementation of such heat preparation. (Research purpose) The research purpose is in expanding the functionality of remote diagnostics by operational monitoring and control of the temperature conditions of individual machine units. (Materials and methods) Authors used research methods based on the application of standard techniques, the object of research was the system of integrated thermal automotive equipment. In addition to heating the engine before starting, other systems and units need to optimize the thermal regime, most of which can be combined into a comprehensive heat treatment system. (Results and discussion) As a result of experimental studies of the integrated heat treatment system mounted on a KAMAZ vehicle, the dynamics of temperature changes in various units during their heat treatment were and presented. Monitoring and controlling the temperature regime of automotive equipment units will reduce internal power losses and increase the service life of units exposed to temperature. (Conclusions) The introduction of a comprehensive heat treatment system, intelligently and functionally linked to a remote monitoring system, will significantly increase the service life of the units most exposed to temperature influences.
