The article presents the results of a study of the energy balance when the technical condition of the fuel pump of agricultural machines changes. Over 30% of internal combustion engine failures occur in the fuel system. Timely diagnostics, repairs and maintenance work (the latter is often not provided for or not performed) of electric fuel pumps can increase the service life and service life. Calculation of the energy balance is a prerequisite for developing a new or upgrading an existing method for diagnosing a fuel pump. The importance of using current strength as a diagnostic parameter (when determining the technical condition) of the pump in the mode of creating maximum pressure in the fuel system is emphasized. Based on the research results, an additional diagnostic parameter can be the rate of increase in the pump supply current. Research has shown that with an increase in the hydraulic resistance of the fuel system by 90%, the average rate of current increase was 7.6 A/s. When the hydraulic resistance of the fuel supply system decreased by less than 10%, the average rate of current increase was 19.2 A/s. Current is a sensitive parameter that increases or decreases depending on the level of increase in hydraulic resistance or leaks in the fuel system. The pump power expended on hydraulic losses did not change significantly due to the constant value of the pump operating voltage. The ideas (methods, techniques) developed in the article are in good agreement with the issues of modeling processes in hydrodynamic tribocouplings of high-pressure fuel pumps, in particular for Common Rail systems. The research was carried out at the expense of the Russian Science Foundation grant No. 23-29-10042, Topic: Numerical modeling of processes in hydrodynamic tribocouplings of high-pressure fuel pumps for advanced high-pressure diesel engines https://rscf.ru/project/23-29-10042/.”
