摘要：

The article presents the results of an experimental study on the influence of hydrogen as gaseous fuel on the combustion process parameters of a single-cylinder diesel engine operating in dual-fuel mode. The study is conducted at an average engine speed of n = 2000 min⁻1, four engine load levels, and two different diesel fuel injection timing angles. Indicator diagrams are recorded for each operating mode at varying hydrogen mass fractions in the total fuel supplied to the engine. The data from the indicator diagrams are processed using a developed software that enables the determination of combustion process parameters. The analysis of the experimental results focuses on changes in cylinder temperature, the coefficients of total and active heat release, the rate of heat release, the duration of the combustion process phases, and other parameters as a function of the hydrogen mass fraction in the total fuel mixture. © 2025 The Authors
