Изобретение относитс к области двигателестроени .The invention relates to the field of engine building.
Известны устройства дл впрыска топлива в двигатель внутреннего сгорани с искровым зажиганием, содержаи,ие размещенные во впускном трубопроводе дроссельную заслонку и заслонку регул тора, св занную с дозирующим клапаном, и перепускную магистраль с регулирующим клапаном.Devices are known for injecting fuel into a spark-ignited internal combustion engine, containing a throttle valve and a regulator valve in the intake manifold associated with the metering valve, and an overflow line with a regulating valve.
С целью предотвращени переобогащени с.меси при резком открытии дроссельной заслонки в предлагаемом устройстве перепускна магистраль подключена к трубопроводу до и после заслонки регул тора, а регулирующий клапан снабжен пружиной и выполнен автоматическим с открытием по перепаду давлени в трубопроводе до и после заслонки регул тора.In order to prevent over-enrichment of the mixture in the proposed device, the overflow line is connected to the pipeline before and after the regulator valve, and the regulating valve is spring-loaded and automatically open with differential pressure in the pipeline before and after the regulator valve.
Кроме того, предлагаемое устройство отличаетс от известных тем, что пружина снабжена механизмом изменени нат жени с управлением от импульса температурного датчика .In addition, the proposed device differs from the known ones in that the spring is equipped with a tension-controlling mechanism with a temperature sensor pulse.
На чертеже изображено предлагаемое устройство дл впрыска топлива в двигатель внутреннего сгорани , разрез.The drawing shows the proposed device for the injection of fuel into the internal combustion engine, the cut.
Оно содержит заслонку 1 регул тора, установленную во впускном трубопроводе 2 и св занную при помощи рычага 3 с дозирующим клапаном (на чертеже не изображен).It contains a damper 1 of the regulator installed in the inlet pipe 2 and connected by means of the lever 3 with the metering valve (not shown).
В трубопроводе 2 за заслонкой 1 регул тора (по направлению движени воздущного потока ) установлена дроссельна заслопка, положением которой задаетс нагрузка двигател .In the pipe 2 behind the valve 1 of the regulator (in the direction of the air flow) a throttle valve is installed, the position of which is the engine load.
Трубопровод 2 снабжен перепускной магистралью 4, подключенной к нему до и после заслонки регул тора. На вы.ходе магистрали 4 установлен клапан 5, снаблуенный 6 и выполненный автоматическим с открытиемPipeline 2 is equipped with a bypass line 4 connected to it before and after the regulator valve. At the output of line 4, valve 5 is installed, equipped with 6 and made automatically with opening
по перепаду давлени до и после заслонки регул тора . Один конец пружины 6 жестко св зан с клапаном 5, а другой - со штоком датчика 7 температуры охлаждающей жидкости двигател .differential pressure before and after the valve of the regulator. One end of the spring 6 is rigidly connected to the valve 5, and the other to the stem of the engine coolant temperature sensor 7.
Устройство работает следующим образом. При работе двигател всасываемый в цилиндры воздух проходит по патрубку 8 в воздухоочиститель 9 и, пройд фильтрующий элемент 10, направл етс во впускной трубопровод 2.The device works as follows. When the engine is running, the air drawn into the cylinders passes through the pipe 8 to the air cleaner 9 and, after passing through the filter element 10, is directed to the intake pipe 2.
Под напором воздущного потока в трубопроводе 2 заслонка регул тора отклон етс . Величина отклонени заслонки регул тора пропорциональна количеству проход щего вUnder the pressure of the air flow in the pipe 2, the regulator flap is deflected. The amount of deviation of the regulator valve is proportional to the amount of
трубопроводе 2 воздуха. Отклонение заслонки регул тора через рычаг 3 передаетс дозирующему клапану, который установлен между топливоподающим насосом и форсунками. Дозирующий клапан пропорционально отклонению заслонки регул тора измен ет колиpipeline 2 air. The deviation of the regulator valve through the lever 3 is transmitted to the metering valve, which is installed between the fuel injection pump and the injectors. The metering valve is proportional to the deviation of the valve of the regulator changes the
