ОПРЕДЕЛЕНИЕ ОПТИМАЛЬНОЙ ТЕМПЕРАТУРЫ МОТОРНОГО МАСЛА, ПРИ КОТОРОЙ ВОЗМОЖЕН ЗАПУСК ДВИГАТЕЛЯ С МИНИМАЛЬНЫМ ИЗНОСОМ

Abstract

The operation of road transport implies not only the transportation of goods and passengers, but also the maintenance of the car itself. When operating road transport at low temperatures, the risk of failure of the main units increases. The most expensive unit is the internal combustion engine, which experiences a tremendous load during the cold start period. This load depends on the viscosity of the engine oil, which, in turn, is directly dependent on temperature. The greatest danger from the point of view of engine operation without lubrication is the period of engine operation after start-up. In order to increase the viscosity of the oil, improve the starting quality of the engine and reduce starting wear, it is necessary to use engine preheating. The purpose of this work is to identify the temperature or temperature range at which it is possible to “safely” start the engine with pre-start preparation at low temperatures. The temperature range depends on the operating conditions of the vehicles, the methods of pre-start preparation of the engine, which in turn affects the time of pre-start preparation. The paper reveals the temperature range for starting an internal combustion engine at low temperatures with the least wear of rubbing parts and minimal pre-launch costs; the recommended engine oil temperatures before starting internal combustion engines are given.
