Изобретение относитс к машиностроению , в частности, двигателе- строении, а именно, к спрсрбам работы двигателей внутреннего сгорани на водородно-воздушных смес хThe invention relates to mechanical engineering, in particular, engine building, namely, to the systems of operation of internal combustion engines in hydrogen-air mixtures.
Цель изобретени - повышение надежности работы путем устранени обратных вспьппек во впускном трактеThe purpose of the invention is to increase the reliability of work by eliminating the return air in the intake tract.
На чертеже изображена схема двиг тел , реализующего предлагаемый способ.The drawing shows a diagram of the engine that implements the proposed method.
Двигатель внутреннего сгорани Содержит цилиндр 1 с поршнем 2 и головку 3 цилиндра, образующие камеру 4 сгорани . Головка 3 цилиндра снабжена впускным клапаном 5. К камере 4 сгорани подключен впускной тракт 6, а к зоне 7 над впускным клапй.ком 5 - магистраль 8.Internal combustion engine Contains cylinder 1 with piston 2 and cylinder head 3, forming a combustion chamber 4. The cylinder head 3 is provided with an intake valve 5. An intake path 6 is connected to the combustion chamber 4, and a main line 8 is connected to zone 7 above the intake valve 5.
Предлагаемый способ реализуетс следующим образом.The proposed method is implemented as follows.
Водород под давлением, которое регулируют в зависимости от режима I работы двигател , подают по магист- рали 8 во впускной тракт 6 в зону 7 над впускным клапаном 5 в непосредственной близости от него. При закрытом клапане 5 приток воздуха во впускной тракт 6 отсутствует, оставшийс в тракте воздух вытесн етс водородом, поступающим под давлением в зону 7. Объемный расход водорода по отношению к расходу воздуха составл ет значительную веСоставитель В.Шилов Редактор Н.Данкулич Техред Л.Микеш Корректор Л.ПатайHydrogen under pressure, which is regulated depending on the engine operation mode I, is fed through line 8 into the intake tract 6 into zone 7 above intake valve 5 in the immediate vicinity of it. When the valve 5 is closed, there is no air flow in the intake path 6, the air remaining in the path is displaced by hydrogen entering zone 7 under pressure. Hydrogen volume flow relative to air flow is considerable. Compiler V.Shilov Editor N.Dankulich Tehred L.Mikesh Proofreader L. Patay

Это обеспечи5 вает образование в зоне 7 над впускным клапаном богатой водородно-воз- душной смеси. В непосредственной близости от впускного клапана 5 концентраци водорода велика, и,lichinu., for example, with 1 and about 40%. In addition, the time when the inlet valve is closed is about 65% of the cycle time. This ensures the formation of a rich hydrogen-air mixture in zone 7 above the inlet valve. In the vicinity of the intake valve 5, the concentration of hydrogen is high, and,
