В статье представлены результаты, которые получены при моделировании рабочего процесса двигателя 1ЧН12/13 с применением программного комплекса AVL FIRE для оценки эффекта повышения давления в топливном аккумуляторе до рак = 300 МПа. Результаты показывают, что увеличение рак повышает интенсивность процесса сгорания. При увеличении давления рак с 150 до 300 МПа содержание оксидов азота NOx уменьшилось на 23,2%, а сажи – на 58,1%. Однако NOx не достигает уровня, соотвествуеющего Евро 6 – 0,4 г/(кВт·ч). Поэтому необходимо использовать рециркуляцию отработавших газов (РОГ) в сочетании со сверхвысоким давлением впрыскивания. При применении степени рециркуляции Rc = 27% выбросы NOx соответствуют стандартам Евро 6. Содержание сажи уменьшилось на 55,6%, NOx – на 93%. Однако, удельный эффективный расход топлива увеличивается на 4,9% при отсутствии РОГ и на 4,7% при Rc = 27%, а индикаторная мощность уменьшилась на 4,3%.</p></abstract><trans-abstract xml:lang="en"><p>The fuel injection pressure is one of the main factors affecting the performance of a diesel engine. The article presents the results obtained by modeling the working process of the 1CHN12/13 engine using the AVL FIRE software package to evaluate the effect of increasing the pressure in the fuel accumulator up to 300 MPa. The results show that an increase in cancer increases the intensity of the combustion process. With an increase in the pressure of the cancer from 150 to 300 MPa, the content of nitrogen oxides NOx decreased by 23.2%, and soot-by 58.1%. However, NOx does not reach the level corresponding to Euro 6-0.4 g/(kW·h). Therefore, it is necessary to use exhaust gas recirculation (EGR) in combination with ultra-high injection pressure. When applying the degree of recirculation Rc = 27%, NOx emissions comply with Euro 6 standards. The soot content decreased by 55.6%, NOx-by 93%. However, the brake fuel consumption increases by 4.9% without EGR and by 4.7% at Rc = 27% and the indicator power decreased by 4.3%.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>дизель</kwd><kwd>сажа</kwd><kwd>NOx</kwd><kwd>сгорание</kwd><kwd>давление впрыскивания топлива 300 МПа</kwd><kwd>рециркуляция отработавших газов.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>diesel engine</kwd><kwd>soot</kwd><kwd>NOx</kwd><kwd>combustion</kwd><kwd>fuel injection pressure up to 300 MPa</kwd><kwd>exhaust gas recirculation.</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">Wloka, J.
