Abstract

Изобретение позвол ет обеспечить возможность фиксации силового, поршн на период запуска в положении максимальной топливоподачи, В корпусе 1 размещена мембрана 2 датчика давлени наддува, св занна со штоком 3, который взаимодействует с рычагом 6. Рычаг 6 воздействует на подпруч жиненный пружиной 11 управл ющий золотник 9, в котором выполнен скво з- ной канал 10. Золотник 9 входит в отверстие силового поршн 12, нагруженного пружиной 13 и образующего с корпусом рабочую полость, соединенную с.каналом 20 через клапан, выполненный в виде подпрзлкиненного поршн 22 со штоком 23. Канал 20 соединен с линией подвода рабочей жидкости. Орган 17 дозировани топливоподачи снабжен выступом 26 дл взаимодействи со штоком 23 поршн 22. В момент запуска двигател силовой поршень 12 обеспечивает возможность перевода органа 17 в положение максимальной топливоподачи, облегчающей запуск . 3 з.п. ф-лы, 3 ип. ш соThe invention allows the power piston to be fixed for the period of start-up in the maximum fuel supply position. In housing 1 there is a diaphragm 2 of a boost pressure sensor connected to the piston rod 3, which interacts with the lever 6. The lever 6 acts on the spring-loaded spool 11 9, in which the squash channel 10 is made. The spool 9 enters the hole of the power piston 12, loaded with spring 13 and forming a working cavity with the body, connected to the channel 20 through a valve, made in the form of Lkinennogo piston 22 with a rod 23. The channel 20 is connected to the line for supplying the working fluid. The fuel metering body 17 is provided with a protrusion 26 for interacting with the piston rod 23 of the piston 22. At the time of starting the engine, the power piston 12 allows the body 17 to move to the maximum fuel delivery position, which makes it easier to start. 3 hp f-ly, 3 pp. sh with

Claims

Claim

1. A device for controlling about 5 fuel supply of a supercharged internal combustion engine, comprising a corrector, in the housing of which a spring-loaded power piston 40 is placed, interacting with the fuel metering body and limiting the working cavity formed in the housing, communicating through the housing supply channel with the working fluid supply line 45 and connected through a control spool with a drain hole, and a boost pressure sensor, the sensing element of which is connected to the shoulder of the control spool50, In that, in order to ensure the fixation of the power piston for the period of starting the engine in the maximum fuel supply position, the device is additionally equipped with a valve mounted on the supply line of the working fluid with the possibility of its overlap, and a valve actuator.

2. The device according to claim 1, characterized in that the valve actuator is made in the form of a protrusion on the fuel metering body interacting with the valve.

3. The device according to claim 1, wherein the valve actuator is made in the form of a control electromagnet, the core of which is connected to the valve, and the winding is equipped with leads for connection to the starter.

$ 4. The device according to claim 1, with the fact that it is equipped with a sensor of the engine operating mode, and the valve actuator is made in the form of a kinematic connection between this sensor and: the valve.
