Abstract

A single-plunger nozzle relates to fuel injection nozzles for mixing an air/fuel mixture and injecting it into the combustion chamber of an ICE. The present nozzle can be used in ICEs of water and land vehicles alike. The technical result of the claimed invention is a broadening of the range of technical means for producing a fuel/air mixture, or a three-component air/fuel/water mixture, and suppling it to the combustion chamber of an ICE of a water or land vehicle. This technical result is achieved in that a single-plunger nozzle comprises a housing with a mixing chamber, a spray tip, an excitation coil, a spring, a fuel injection nozzle, a shut-off plunger, a core of an electromagnet, sealing gaskets, and a cover, wherein a guide assembly consists of at least one labyrinth seal and the claimed nozzle further comprises a connector, provided with a check valve, to which an air conduit can be mounted, and a connector to which a water injector or a plug can be mounted. The entire inside surface of the mixing chamber and the shut-off plunger are highly polished, which reduces fuel build-up on the walls of the mixing chamber and the surface of the plunger, which in turn reduces fuel loss.

Из уровня техники, патент WO 2008/104423 (04.09.2008), № 2480614 конвенционным приоритетом от 26.02.2007г. известна топливная форсунка для впрыскивания топлива в камеру сгорания в двигателе внутреннего сгорания, имеющая расположенный в ее корпусе с возможностью направленного возвратно-поступательного перемещения поршень управляющего клапана, управляющего возвратно-поступательным перемещением поршня и имеющего установленную с возможностью направленного возвратнопоступательного перемещения вдоль соответствующей оси иглу с направляющим отверстием, в которое входит предусмотренная на конце форсуночной детали направляющая часть для направления иглы при ее возвратно-поступательном перемещении, при этом вдоль указанной оси через форсуночную деталь до направляющей части проходит подъемное отверстие, через которое топливо может перетекать из управляющей полости для управления возвратно-поступательным перемещением поршня в расположенную между направляющим отверстием и направляющей частью кольцевую полость с прохождением при этом через по меньшей мере один сливной дроссель, расположенный в зоне перехода от подъемного отверстия к кольцевой полости, отличающаяся тем, что подъемное отверстие оканчивается в проходящем поперечно ему в направляющей части вдоль своей оси поперечном отверстии и перед входом в это поперечное отверстие имеет сужающую проходное сечение дросселирующую геометрию для образования сливного дросселя. From the prior art, patent WO 2008/104423 (09/04/2008), No. 2480614 with convention priority dated 02/26/2007. a fuel injector is known for injecting fuel into the combustion chamber of an internal combustion engine, having a control valve piston located in its body with the possibility of directed reciprocating movement, controlling the reciprocating movement of the piston and having a needle with a guide installed with the possibility of directed reciprocating movement along the corresponding axis a hole into which a guide part provided at the end of the injector part enters to guide the needle during its reciprocating movement, while along said axis through the nozzle part to the guide part there is a lifting hole through which fuel can flow from the control cavity to control the reciprocating by moving the piston into an annular cavity located between the guide hole and the guide part, passing through at least one drain throttle located in the transition zone from the lifting hole to the annular cavity, characterized in that the lift hole ends in a cross-section running along the guide part its axis of the transverse hole and before the entrance to this transverse hole has a throttling geometry that narrows the flow area to form a drain throttle.
Но данное устройство позволяет уменьшить кавитацию в потоке топлива в зоне сливного дросселя но не позволяет получить воздушно-топливную смесь и подать её в камеру сгорания ДВС But this device allows you to reduce cavitation in the fuel flow in the drain choke area but does not allow you to obtain an air-fuel mixture and feed it into the combustion chamber of the internal combustion engine
Самым близким по своей технической сущности является, известный из патента № 2468244 с конвенционным приоритетом от 21.06.07г. Топливная форсунка для впрыскивания топлива в камеру сгорания в двигателе внутреннего сгорания, прежде всего форсунка для системы "common rail", имеющая управляющий клапан, позволяющий воздействовать на давление топлива в управляющей полости, ограниченной клапанным элементом топливной форсунки, перемещающимся в зависимости от давления топлива в управляющей полости между закрытым положением и освобождающим путь прохождения топлива в камеру сгорания открытым положением The closest in its technical essence is known from patent No. 2468244 with convention priority dated June 21, 2007. Fuel injector for injecting fuel into the combustion chamber of an internal combustion engine, primarily an injector for the common rail system, having a control valve that allows it to act on fuel pressure in the control cavity, limited by the valve element of the fuel injector, which moves, depending on the fuel pressure in the control cavity, between the closed position and the open position, which clears the path for the fuel to pass into the combustion chamber
Но данное устройство не позволяет получать воздушно-водно-топливную смесь и высоко гомогенизировать её. But this device does not allow obtaining an air-water-fuel mixture and highly homogenizing it.
Техническим результатом заявленного изобретения является расширение технических средств для получения воздушно-топливной смеси или трехкомпонентной воздушно-топливно-водяной смеси и подачи её в камеру сгорания ДВС как водного, так и наземного транспорта. The technical result of the claimed invention is the expansion of technical means for obtaining an air-fuel mixture or a three-component air-fuel-water mixture and feeding it into the combustion chamber of internal combustion engines of both water and land transport.
Указанный технический результат достигается за счет того, что одноштоковая форсунка содержит корпус с камерой смешения, сопло, обмотку возбуждения, прижимную пружину, топливную форсунку, запорный шток, сердечник электромагнита, уплотнительные прокладки, крышку причем направляющий блок состоит из по крайней мере одного лабиринтного уплотнения, кроме того дополнительно содержит штуцер снабженный обратным клапаном и позволяющий установку воздушного трубопровода и штуцер позволяющий установку водяной форсунки или заглушки. Вся внутренняя поверхность камеры смешения и запорный шток отполированы до зеркального блеска, что уменьшает оседание топлива на стенках камеры смешения и поверхности штока, что в свою очередь сокращает потери топлива. Лабиринтные уплотнения выполнены например из стали, латуни или бронзы, и представляют собой например уплотнительные кольца с выполненными в них канавками, где в шахматном порядке чередуются гребень и выемка, что позволяют держать в камере смешения очень высокое давление, предотвращает выход смеси из камеры смешения, а кроме того выполнять роль направляющих предотвращая хождения запорного штока из стороны в сторону при его работе. Предложенная конструкция форсунки позволяет использовать смесь из трех компонентов топлива, воздуха и воды. А также способствует более полной гомогенизации топлива перед подачей его в ДВС. Высокая гомогенизация топлива позволяет без применения более высоко октанового топлива поднять степень сжатия в цилиндре, тем самым улучшить такие показатели как мощность, крутящий момент, экономичность и экологичность. Поскольку в цилиндре ДВС на малых и средних оборотах двигателя температура не высокая, то ЭБУ (электронный блок управления) блокирует систему впрыска воды до 4, 5 тыс. оборотов в минуту, по достижении 4,5 тыс. оборотов ЭБУ разблокирует систему и капитан или водитель транспортного средства имеет возможность включить её кнопкой на посту управления. Как только система впрыска воды начала работу ЭБУ двигателя дозирует количество подаваемой воды в зависимости от оборотов двигателя. Больше оборотов - больше подача воды, таким образом можно менять процентное содержание воды в топливо-воздушной смеси. При падении оборотов двигателя ниже 4,5 тыс. оборотов в минуту ЭБУ блокирует подачу воды независимо от того, включена была система или нет. The specified technical result is achieved due to the fact that the single-rod injector contains a housing with a mixing chamber, a nozzle, an excitation winding, a pressure spring, a fuel injector, a shut-off rod, an electromagnet core, sealing gaskets, a cover, wherein the guide block consists of at least one labyrinth seal, in addition, it additionally contains a fitting equipped with a check valve and allowing the installation of an air pipeline and a fitting allowing the installation of a water nozzle or plug. The entire internal surface of the mixing chamber and the shut-off rod are polished to a mirror finish, which reduces fuel deposition on the walls of the mixing chamber and the surface of the rod, which in turn reduces fuel losses. Labyrinth seals are made, for example, of steel, brass or bronze, and are, for example, sealing rings with grooves made in them, where a ridge and a recess alternate in a checkerboard pattern, which makes it possible to maintain very high pressure in the mixing chamber, prevents the mixture from leaving the mixing chamber, and in addition, act as guides, preventing the shut-off rod from moving from side to side during its operation. The proposed nozzle design allows the use of a mixture of three components of fuel, air and water. It also promotes more complete homogenization of the fuel before feeding it into the internal combustion engine. High homogenization of the fuel allows you to increase the compression ratio in the cylinder without using higher octane fuel, thereby improving such indicators as power, torque, efficiency and environmental friendliness. Since the temperature in the internal combustion engine cylinder at low and medium engine speeds is not high, the ECU (electronic control unit) blocks the water injection system up to 4.5 thousand revolutions per minute, upon reaching 4.5 thousand revolutions the ECU unlocks the system and the captain or driver the vehicle has the ability to turn it on with a button at the control post. As soon as the system water injection has started operation The engine ECU doses the amount of water supplied depending on the engine speed. More revolutions means more water supply, thus you can change the percentage of water in the fuel-air mixture. When the engine speed drops below 4.5 thousand rpm, the ECU blocks the water supply regardless of whether the system was turned on or not.
Суть технического решения поясняется иллюстрацией где на фигуре 1 изображен корпус с камерой смешения 1, топливная форсунка 2, запорный шток 3, штуцер 4, уплотнительные прокладки 5, крышка 6, лабиринтное уплотнение 7, сердечник электромагнита 8, обмотка возбуждения 9, прижимная пружина 10, сопло 11, обратный клапан 12, штуцер 13. The essence of the technical solution is illustrated by the illustration where figure 1 shows a housing with a mixing chamber 1, a fuel injector 2, a shut-off rod 3, a fitting 4, sealing gaskets 5, a cover 6, a labyrinth seal 7, an electromagnet core 8, an excitation winding 9, a pressure spring 10, nozzle 11, check valve 12, fitting 13.
Одноштоковая форсунка работает следующим образом. Шток 3 опущен, сопло 11 закрыто, водяная форсунка (на рисунке не показана), установленная в штуцер 13 производит впрыск необходимого количества воды под давлением, превышающим давление внутри камеры смешения, например 10 атм. Как только водяная форсунка впрыснула необходимое количество воды в смесительную камеру 1 топливная форсунка 2 производит впрыск необходимого количества топлива под давлением, превышающим давление внутри камеры смешения, например 12 и выше атм. При этом обратный клапан 12 закрыт, поскольку давление внутри камеры смешения 1 выше, чем давление в штуцере 4. В камере смешения 1 происходит активное перемешивание воздуха, воды и топлива, т. е. гомогенизация. Для впрыска топливной смеси в камеру сгорания ДВС на обмотку возбуждения 9 подается электрический ток, который протягивая сердечник электромагнита 8 перемещая запорный шток 3 вверх. Запорный шток 3 открывает сопло 11 и происходит подача топливной смеси в камеру сгорания ДВС, при этом оставшаяся в камере смешения 1 топливная смесь выдавливается давлением воздуха, который подается из штуцера 4 открывая подпружиненный клапан 12. Подаваемый под давлением воздух продувает внутренний объём камеры смешения 1 от остатков топливной смеси, после чего запорный шток 3 с помощью прижимной пружины 10 опускается, закрывая сопло 11, и далее цикл повторяется. A single-rod nozzle works as follows. Rod 3 is lowered, nozzle 11 is closed, a water nozzle (not shown in the figure) installed in fitting 13 injects the required amount of water under a pressure exceeding the pressure inside the mixing chamber, for example 10 atm. As soon as the water injector has injected the required amount of water into the mixing chamber 1, the fuel injector 2 injects the required amount of fuel at a pressure exceeding the pressure inside the mixing chamber, for example 12 atm or higher. In this case, the check valve 12 is closed, since the pressure inside the mixing chamber 1 is higher than the pressure in the fitting 4. In the mixing chamber 1, active mixing of air, water and fuel occurs, i.e. homogenization. To inject the fuel mixture into the combustion chamber of the internal combustion engine, an electric current is supplied to the excitation winding 9, which pulls the core of the electromagnet 8 and moves the shut-off rod 3 upward. The shut-off rod 3 opens the nozzle 11 and the fuel mixture is supplied to the combustion chamber of the internal combustion engine, while the fuel mixture remaining in the mixing chamber 1 is squeezed out by air pressure, which is supplied from fitting 4, opening the spring-loaded valve 12. The air supplied under pressure blows the internal volume of the mixing chamber 1 from remaining fuel mixture, after which the shut-off rod 3 is lowered with the help of a pressure spring 10, closing the nozzle 11, and then the cycle is repeated.
