Построена индикаторная диаграмма и дан анализ работы поршневого двигателя на бензинвоздушных смесях, обогащенных водородом в размере 0…20 % от объема поступающего в двигатель воздуха. Показана возможность получения удовлетворительных показателей при работе на бензине с добавками водорода. Исследовано изменение работы двигателя в зависимости от коэффициента избытка окислителя. Установлено, что коэффициент избытка окислителя, при котором достигается максимум индикаторного давления, смещается в область бедных смесей. При обогащении смеси водородом в размере 20 % от объема воздуха максимум индикаторного давления, равный pimax = 5,3…5,8 МПа, достигается при α = 1,15…1,25, а при 10%-ной добавке водорода имеет место максимум pimax = 4,9…5,2 МПа при α = 1,05…1,10 против pimax = 4,7…5,1 МПа при α = 0,90…0,95 для чистого бензина. По индикаторной диаграмме изучена динамика внутрицилиндровых параметров при обогащении смеси водородом. Так, при 20%-ной добавке водорода среднее индикаторное давление падает на 12…19 %, несмотря на некоторое возрастание максимального давления цикла (на 3…18 %), по сравнению с работой на бензине, что ведет к пропорциональному снижению как индикаторной мощности двигателя, так и индикаторного КПД.</p></abstract><trans-abstract xml:lang="en"><p>The effect of hydrogen additives on the working process of a piston-type gasoline engine is studied. The indicator diagram has been built, and the operation of the piston engine on gasoline-air mixtures enriched with hydrogen in the amount of 0…20 % of the volume of air entering the engine has been analyzed. The possibility of obtaining satisfactory parameters when the engine works on gasoline with hydrogen additives is shown. The dynamics of the engine performance is studied depending on the oxidant excess coefficient. It has been established that the oxidizer excess ratio at which the maximum indicator pressure is reached is moved to the zone of poor mixtures. When the mixture is enriched with hydrogen in the amount of 20 % of the air volume, the maximum of indicator pressure pimax = 5.3...5.8 MPa is reached at α = 1.15...1.25, while for 10 % hydrogen addition the maximum pimax = 4.9...5.2 MPa takes place at α = 1.05...1.10 against pimax = 4.7...5.1 MPa at α = 0.90...0.95 for pure gasoline. According to the indicator diagram, the dynamics of intra-cylinder parameters is studied when the mixture is enriched with hydrogen. Thus, with a 20 % hydrogen addition the mean indicator pressure decreases by 12...19 %, despite a slight increase in the maximum cycle pressure (3...18 %), compared with gasoline operation, which leads to a proportional decrease in both the engine indicator power, and the indicator efficiency.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>поршневой двигатель</kwd><kwd>бензин</kwd><kwd>водород</kwd><kwd>индикаторная диаграмма</kwd><kwd>индикаторное давление</kwd><kwd>коэффициент избытка окислителя</kwd></kwd-group><kwd-group xml:lang="en"><kwd>piston engine</kwd><kwd>gasoline</kwd><kwd>hydrogen</kwd><kwd>indicator diagram</kwd><kwd>indicator pressure</kwd><kwd>oxidant excess ratio</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">Andrea, T.
