SUBSTATIATION OF THE WORKING FLUID TEMPERATURE WHEN TESTING DIESEL INJECTORS

Abstract

This paper substantiates the permissible temperature limits of the working fluid when testing diesel fuel equipment. The normative and technical documentation does not indicate the optimum temperature of the working fluid during the test. The results are confirmed by experimental data obtained on a device developed by the authors for evaluating the injection characteristics. The developed device was based on the method of fuel injection into a long pipeline. The tests revealed the effect of fuel temperature on the performance of diesel fuel equipment. Also, the tests proved that in order to obtain reliable indicators when diagnosing diesel fuel equipment it is necessary to stably maintain the operating temperature of the device in the range of 60 ± 5 °С.
