Abstract
The purpose of this study was to improve the diagnostics efficiency of modern diesel engine injectors with electronic controls. Experimental studies, performed using certified specialized equipment of injectors' manufacturers and standard software packages for data analysis, made it possible to prove adequacy of theoretical research and get results that are more accurate. Those results contribute to development of a software product that allows identifying a particular faulty element during the defective injector's operation by using mathematical processing of the diagnostic data obtained when testing the injector. Thus, the time spent to repair the fuel injection system reduces. The developed software product also helps to predict the remaining injector's operational life and prevent possible technical failures during operation.

Summary
Common Rail fuel injection system is widely used in modern automotive and agricultural machinery. In engines with this system, the fuel pressure creation and fuel distribution inside the cylinder occur over time. Since this system is relatively new, manufacturers do not disclose diagnostic technologies. Various diagnostic methods are used to assess the technical conditions of the fuel supply system (Table 1). These methods are applied in accordance with the diagnostics tasks
