Description
(54) УСТРОЙСТВО ДЛЯ ПОДАЧИ ТОПЛИВА В ДВИГАТЕЛЬ ВНУТРЕННЕГО СГОРАНИЯ(54) DEVICE FOR FUELING FUEL IN INTERNAL COMBUSTION ENGINE
подключенным параллельно главному жиклеру 8 и снабженным гидравлическим дросселем И н запорным органом 12 с электромагнитом 13, подключенным при помощи клемм 14 к управл ющему блоку (не изображен ). Уровень топлива в топливной камере 6 поддерживаетс посто нным при помощи поплавка 15 и св занного с ним клапана 16, перекрывающего подвод щий трубопровод 17, соединенный с подкачивающим насосом (не изображен).connected in parallel to the main jet 8 and fitted with a hydraulic throttle AND a shut-off member 12 with an electromagnet 13 connected via terminals 14 to the control unit (not shown). The fuel level in the fuel chamber 6 is kept constant by means of a float 15 and a valve 16 connected to it, closing the supply line 17 connected to a booster pump (not shown).
При работе двигател всасываемый воздух проходит через проточный канал 2, и расход воздуха регулируетс дроссельной заслонкой 3, управл емой оператором. В зависимости от расхода воздуха измен етс положение золотника 4 относительно корпуса, в св зи с чем регулируетс разрежение у выходного жиклера 9 и иглой 5 его проходное сечение. Под действием разрежени топливо из топливной камеры 6 по топливопроводу 7 поступает к выходному жиклеру 9 и затем распыл етс во всасываемом в цилиндры двигател воздухе, образу топливовоздушную смесь. Количество топлива, поступающего из выходного жиклера 9, определ етс величиной разрежени и проходными сечени ми жиклеров 8 и 9, когда гидравлический дроссель 11 обводного канала 10 перекрыт запорным оргном 12. Таким образом устанавливаетс состав смеси, поступающей к двигателю.When the engine is running, the intake air passes through the flow channel 2, and the air flow is controlled by the throttle valve 3 controlled by the operator. Depending on the air flow, the position of the spool 4 relative to the body changes, in connection with which the vacuum at the outlet nozzle 9 and the needle 5 of its flow section are regulated. Under the action of dilution, the fuel from the fuel chamber 6 flows through the fuel line 7 to the outlet nozzle 9 and then is sprayed into the air drawn into the engine cylinders to form an air-fuel mixture. The amount of fuel coming from the output jet 9 is determined by the magnitude of the vacuum and the flow sections of the nozzles 8 and 9 when the hydraulic throttle 11 of the bypass channel 10 is blocked by the shut-off valve 12. Thus, the composition of the mixture entering the engine is determined.
Дл изменени состава смеси в зависимости от состо ни атмосферного воздуха и режимов работы двигател управл ющий блок, след щий за параметрами работы двигател , например, по составу отработавших газов, выдает управл ющие импульсы к электромагниту 13, который перемещает запорный орган 12 в положение открыти гидравлического дроссел 11. В этом положении количество топлива, проход щего через главный жиклер 8, суммируетс с количеством топлива, проход щего по обводному каналу 10, в св зи с чем увеличиваетс количество топлива, поступающего из выходного жиклера 9, а количество воздуха, проход щего по проточному каналу 2, остаетс неизменным. Поэтому измен етс состав смеси, поступающей в сумматоры двигател , до такой величины, пока не установитс заданный состав отработавших газов. В результате снижаетс токсичность отработавших газов.To change the composition of the mixture, depending on the state of atmospheric air and engine operating modes, the control unit, which follows the parameters of the engine, for example, the composition of the exhaust gases, gives control pulses to the electromagnet 13, which moves the locking member 12 to the open hydraulic position throttle 11. In this position, the amount of fuel passing through the main jet 8 is summed with the amount of fuel passing through the bypass channel 10, in connection with which the amount of fuel increases, coming from the outlet nozzle 9, and the amount of air passing through the flow channel 2 remains unchanged. Therefore, the composition of the mixture entering the engine accumulators is changed to such an extent until the desired composition of the exhaust gases is established. As a result, exhaust emissions are reduced.
В устройстве, показанном на фиг. 2, в топливопроводе 7 установлен главный жиклер 18 переменного сечени , который расположен непосредственно под выходным жиклером 9. Таким образом, дозирующей иглой 5 золотника 4 обеспечиваетс изменение проходного сечени выходного жиклера 9 в функции к проходному сечению главного жиклера переменного сечени , вIn the device shown in FIG. 2, the main jet of variable cross section 18 is installed in the fuel line 7, which is located directly under the outlet jet 9. Thus, the metering needle 5 of the spool 4 allows the output jet 9 of the outlet jet 9 to change as a function of the variable cross section of the main jet
св зи с чем при работе двигател возмол но достижение полной линеаризации между количеством проход щего по проточному каналу 2 воздуха и количеством подаваемого в двигатель топлива.In this connection, during the operation of the engine, it is possible to achieve a complete linearization between the amount of air passing through the flow channel 2 and the amount of fuel supplied to the engine.
Это устройство работает аналогично устройству , показанному на фиг. 1.This device works similarly to the device shown in FIG. one.
Предлагаемое устройство позвол ет обеспечить регулирование состава смеси в зависимости от различных параметровThe proposed device allows controlling the composition of the mixture depending on various parameters.
