Проведён комплексный анализ ключевых факторов, влияющих на процесс сгорания, экологические и экономические показатели данных газовых двигателей. Особое внимание уделено инновационным подходам к оптимизации рабочего процесса, включая прецизионное регулирование состава смеси, применение комбинированных систем наддува, рециркуляцию отработавших газов (EGR) и использование перспективных систем зажигания с высокой энергией. Представлен детальный обзор последних научных исследований и экспериментальных данных, подтверждающих эффективность предложенных технических решений. На основании проведённого анализа сформулированы рекомендации по выбору оптимальных параметров рабочего процесса для различных режимов эксплуатации. Также приведены результаты экспериментов и математическая модель газового двигателя, созданная с опорой на экспериментальные данные.</p></abstract><trans-abstract xml:lang="en"><p>The article discusses modern methods for improving the efficiency of gas engines running on a depleted fuel-air mixture. A comprehensive analysis of the key factors influencing the combustion process, environmental and economic indicators has been carried out. Special attention is paid to innovative approaches to optimizing the workflow, including precision control of the mixture composition, the use of combined boost systems, exhaust gas recirculation (EGR) and the use of advanced high-energy ignition systems. A detailed review of the latest scientific research and experimental data confirming the effectiveness of the proposed technical solutions is presented. Based on the analysis, recommendations have been formulated on the selection of optimal workflow parameters for various operating modes. Experimental results and a mathematical model of a gas engine based on experimental data are also presented.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>газовый двигатель</kwd><kwd>обеднённая смесь</kwd><kwd>оптимизация рабочего процесса</kwd><kwd>EGR</kwd><kwd>турбонаддув</kwd><kwd>комбинированный наддув</kwd><kwd>система зажигания</kwd><kwd>экологические показатели</kwd><kwd>топливная экономичность</kwd><kwd>цикловая нестабильность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>gas engine</kwd><kwd>lean mixture</kwd><kwd>workflow optimization</kwd><kwd>EGR</kwd><kwd>turbocharging</kwd><kwd>combined boost</kwd><kwd>ignition system</kwd><kwd>environmental performance</kwd><kwd>fuel efficiency</kwd><kwd>cyclic instability</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Cho, H.
