Abstract

In engineering practice, forecasting is considered to be the most effective methods for assessing reliability indicators and determining expected technical and economic indicators, taking into account the technical level of improving the diesel power system. The solution of such problems requires a description of changes in the parameters of objects at different points in time. The purpose of the research is to predict the possible values of the fuel injection pressure of the Common Rail system for the near future for the timely creation of operating conditions, maintenance and repair measures. A statistical method was used to predict changes in the fuel injection pressure in the diesel power system. The forecasting technique included the stages of analyzing the initial information, choosing the analytical dependence of the change in the considered parameter in the past, extrapolating the resulting dependence for the forecast period and evaluating the results. The choice of analytical dependences of changes in the estimated pressure value was carried out by the method of least squares. The degree of connection between the considered analytical dependence and the line constructed from the initial data was determined by the value of the correlation coefficient. As the technical, economic and environmental requirements become more stringent, the requirements for the power supply system of internal combustion engines are growing, which necessitates an increase in the functionality of the fuel equipment, primarily in terms of the value of the fuel injection pressure. The paper considers the results of a predictive assessment of possible values of injection pressure of the Common Rail fuel system. The results of the study make it possible to predict an increase in the fuel injection pressure of the Common Rail system by 2026 up to 300 MPa. To ensure high indicators of technical readiness of the enterprises of technical service of diesel fuel equipment, it is necessary to take into account possible changes in the values of the fuel injection pressure in the future
