Обзор литературы показал, что научной стороной вопроса совершенствования конструкции впускных клапанов занимаются ученые и инженеры ведущих университетов и технологических компаний во всем мире. До конца не решенные научные вопросы сдерживают широкомасштабное применение в судовых дизельных двигателях клапанов с ширмами и спиральными направляющими. Поэтому дальнейшие исследования в данной области являются актуальной задачей. В статье представлены результаты исследования влияния угла охвата ширмы и спиральных направляющих на впускном клапане на коэффициент наполнения, вихревое число, среднюю и пульсационную скорости воздушного вихря в цилиндре судового дизельного двигателя 16Д49. В основе математической модели рабочего процесса судового двигателя были использованы трехмерные уравнения нестационарного переноса. Для определения характеристик турбулентности использовалась k-ω SST модель турбулентности. Выявлено, что применение клапанов с направляющими вставками способствует формированию организованного упорядоченного движения воздуха вокруг оси цилиндра двигателя, уменьшению коэффициента наполнения на 1 — 4 %, увеличению вихревого числа в 2,7 раза, уменьшению пульсационной скорости в 3,9 раза и увеличению средней скорости потока в 3,6 раза. Показано, что использование клапанов с направляющими вставками может быть актуальным решением для организации вихревого движения воздуха в цилиндре судового двигателя.</p></abstract><trans-abstract xml:lang="en"><p>The influence patterns of the intake valve shape on the characteristics of the air vortex in the cylinder of a marine engine are studied. The literature review showed that the scientific side of the issue of improving the design of intake valves is studied by scientists and engineers from leading universities and technology companies around the world. Unresolved scientific issues hinder the large-scale use of valves with screens and spiral guides in marine diesel engines. Therefore, further research in this area is an urgent task. The article presents the results of a study of the influence of the wrap angle of the screen and spiral guides on the intake valve on the filling factor, swirl number, average and pulsation velocities of the air vortex in the cylinder of the 16D49 marine diesel engine. The mathematical model of the working process of the marine engine was based on three-dimensional equations of unsteady transfer. The k-ω SST turbulence model was used to determine the turbulence characteristics. It was found that the use of valves with guide inserts contributes to the formation of an organized orderly air movement around the engine cylinder axis; reduction of the filling factor by 1 — 4 %; increase of the swirl number by 2.7 times; reduction of the pulsation velocity by 3.9 times and increase of the average flow velocity by 3.6 times. It is shown that the use of valves with guide inserts can be a relevant solution for organizing the vortex movement of air in the cylinder of a marine engine.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>впускной клапан</kwd><kwd>турбулентность</kwd><kwd>коэффициент наполнения</kwd><kwd>пульсационная скорость</kwd><kwd>вихревое число</kwd><kwd>CFD-моделирование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>inlet valve</kwd><kwd>turbulence</kwd><kwd>filling coefficient</kwd><kwd>pulsation velocity</kwd><kwd>swirl number</kwd><kwd>CFD modeling</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">Шурпяк В.К.
