Resumen

Introduction: Over time, demands on internal combustion engines are increasing, with a focus on fuel efficiency, emissions reduction, improved reliability, and cost-effective production and operation. Studying diesel engines like the 2CH10.5/13 is relevant due to their significant potential in the modern world. The purpose of study is to investigate the theoretical effect of the initial fuel injection pressure on the combustion process, engine braking performance and efficiency. Materials and Methods: The paper describes the methods of choosing injectors for diesel engines with a high-pressure fuel system. Results and Discussion: Using mathematical calculations and modeling is an effective means to prevent engine operation issues. Developing a dedicated calculation method is necessary to understand the impact of diesel fuel ignition volume on engine performance parameters. The results of experimental studies, which included non-motorised, motorised, and operational tests of diesel nozzles, are also presented. Studies have shown that after 4,000 cumulative hours of operation, the residual life of the injector nozzles is insignificant, since the dynamic performance of the diesel engine decreases to the limit value (7%). Conclusions: This may indicate the need for regular maintenance and replacement of nozzles in accordance with the manufacturer’s recommendations.
