The necessity of adjusting the regulatory documentation for the operation of automotive equipment at low temperatures and the development of an “Integrated thermal training system” for it are substantiated. The description of the main components of the heat treatment system and the methods of the heat treatment are given by the example of a hot gas generator. The methods of thermal preparation of ATT, as well as ways to reduce the temperature of the coolant of the generator of hot gases and increase its efficiency, are considered.
Introduction. In this article the study subject is the power supply system of the pre-start heater. The purpose of the study is to evaluate the possibility of using a thermoelectric generator to power the liquid preheater with optimization of the flow section of the thermoelectric generator heat exchanger.
Materials and Methods. It is proposed to use a thermoelectric generator as an additional energy source to reduce electric power consumption by a pre-start heater. In the course of the study, various structures of the flow section of the thermoelectric generator heat exchanger have been modeled. The thermal and hydrodynamic analyses were carried out in the software environment ANSYS Workbench, Solidworks Flow Simulation to develop the most effective design for the flow section of the thermoelectric generator heat exchanger
Results. An experimental installation was assembled and the dependence of the temperature modes of the pre-start heater on the output parameters of the thermoelectric generator was determined.
Discussion and Conclusion. It has been proved the possibility of reducing the power consumption of the vehicle battery during thermal preparation of the internal combustion engine by using a thermoelectric generator adapted to the power supply system of the liquid pre-start heater.
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.
