OPERATIONAL AND PRODUCTION RESULTS OF RESEARCH ON THE ADAPTATION OF ENERGY FACILITIES TO LOW-TEMPERATURE USE

Abstract

The natural conditions of the Amur region are characterized by the low temperatures up to minus 35-40 degrees Celsius in winter. Production experience shows that currently produced KamAZ family cars are not fully adapted for operation in such conditions, therefore they cannot realize all their potential operational capabilities. (Research purpose) The research purpose is to increase the efficiency of using KamAZ-55111 family cars by installing additional devices that help maintain an optimal temperature mode in operation, allowing the units to adapt to winter operating conditions. (Materials and methods) One of the effective methods is adaptation to natural and industrial operating conditions, in particular, hydraulic and fuel systems as the main ones responsible for the operability, as well as improving the start-up qualities of the engine through the use of electric heating devices and recovery modules using the heat of the exhaust gases. The article presents the serial KamAZ-55111 and KamAZ-55111, adapted to low-temperature conditions, with a thermoelectric heating module installed, a heat storage device of the battery and a belt heater of the coarse fuel filter. (Results and discussion) The results of research on improving the efficiency of the use of KAMAZ family cars in their adaptation to operation in low temperatures were presented. (Conclusions) The issue under consideration is especially relevant in the agricultural production of regions with a long cold period, since the operation of cars in rural areas differs significantly from operation at transport enterprises and in urban conditions.
