Description
Изобретение касаетс устройства дл впрыска топлива в двигател х внутреннего сгорани с использованием перепада давлений, возникающего между цилиндром и предкамерой , сообщенных между собой дополнительным газоперепускным каналом . Топливо вводитс в канал под некоторым статическим напором в период смены рабочего зар да в цилиндре двигател и выталкиваетс в предкамеру на такте сжати .The invention relates to a device for fuel injection in internal combustion engines using the pressure differential between the cylinder and the pre-chamber, which are interconnected by an additional gas passage channel. The fuel is introduced into the channel under a certain static pressure during the change of the working charge in the engine cylinder and is pushed into the prechamber during the compression stroke.
Отличительной особенностью предлагаемого устройства вл етс то, что дл предотвращени перетекани гор чих газов через газоперепускной канал в периоды, когда давление в предкамере превышает давление в цилиндре, газоперепускной канал одним устьем открыт в полость цилиндра,, а другим в горловину , сообщающую цилиндр с предкамерой.A distinctive feature of the proposed device is that to prevent the flow of hot gases through the gas passage channel during periods when the pressure in the prechamber exceeds the pressure in the cylinder, the gas passage channel is open to the cavity of the cylinder and the other to the cylinder that connects the cylinder to the prechamber.
На чертеже изображена схема предлагаемого устройства.The drawing shows a diagram of the proposed device.
Полость цилиндра 2 двигател и полость предкамеры / сообщаютс горловиной 6, котора в средней 27The cavity of cylinder 2 of the engine and the cavity of the prechamber / are communicated by the throat 6, which in the middle 27
части имеет небольшой цилиндрический участок.parts has a small cylindrical section.
Один конец газоперепускного канала 3 открыт в полость цилиндра 2, а другой - в полость -цилиндрической части горловины 6. Такое соединение позвол ет предотвратить перетекание гор чих газов в периоды , когда давление в предкамере / выше давлени в цилиндре J.One end of the gas passage 3 is open into the cavity of cylinder 2, and the other into the cavity of the cylindrical part of the neck 6. This connection prevents the flow of hot gases during periods when the pressure in the prechamber is higher than the pressure in cylinder J.
Средн часть газоперепускного канала 3 соединена с топливоподвод щей системой, причем в этой части канал 3 имеет небольщой изгиб , который обеспечивает некоторое накопление топлива до момента выталкивани его из канала 3.The middle part of the gas passage channel 3 is connected to the fuel supply system, and in this part channel 3 has a slight bend, which provides some accumulation of fuel until it is ejected from channel 3.
Работа устройства протекает следующим образом.The operation of the device proceeds as follows.
В периоды смены рабочего зар да в цилиндре 2 двигател топливо под некоторым статическим давлением поступает из бака 7 через кран 3, наход щийс под воздействием регул тора числа оборотов, и обратный клапан 4 в газоперепускной канал 3.During periods of working charge change in the cylinder 2 of the engine, fuel under some static pressure comes from tank 7 through valve 3, which is under the influence of the speed regulator, and check valve 4 to the gas passage channel 3.
