Description

впускном трубопроводе 1 за дроссельной заслонкой 2 относительно потока воздуха. Распылитель 22 при помощи патрубка 24 соединен с полостью впускного тракта до дроссельной заслонки и образует с ним обводной канал .the inlet pipe 1 behind the throttle valve 2 relative to the air flow. The spray gun 22 by means of a nozzle 24 is connected to the cavity of the intake path to the throttle valve and forms a bypass channel with it.

Трубопровод 4 подключен к выходу топливного насоса 25, обеспечивающего давление на выходе примерно 0,2 атм.The pipe 4 is connected to the outlet of the fuel pump 25, which provides an outlet pressure of approximately 0.2 atm.

В корпусе 6 установлен подпружиненный сливной клапан 26, обеспечивающий давление в камере 5 примерно 0,15 атм и перепускающий топливо в трубопровод 27, соединенный с впускным патрубком 28 насоса 25.In the housing 6 is installed spring-loaded drain valve 26, which provides pressure in the chamber 5 of approximately 0.15 ATM and bypassing the fuel in the pipe 27 connected to the inlet pipe 28 of the pump 25.

Устройство работает следующим образом.The device works as follows.

Топливо из бака (на чертеже не изображен ) по трубопроводу 27 поступает к насосу 25, который по трубопроводу 4 нагнетает топливо под небольшим избыточным давлением в камеру 5. В последней поддерживаетс  посто нное избыточное давление, например, 0,15 атм при помощи клапана 26. Из камеры 5 топливо через зазор между седлом 8 и дозирующим органом 7 поступает в трубопровод 3, из которого, смещива сь с воздухом, поступающим по патрубку 24, направл етс  в распылитель 22. Выход ща  из распылител  22 топливо-воздущна  эмульси  смешиваетс  с воздухом, проход щим по трубопроводу 1. Количество и состав поступающей в цилиндры смеси определ етс  открытием дроссельной заслонки, задаваемым положением педали акселератора и положением дозирующего органа 7, которое определ етс  величиной усилий, одно из которых передаетс  через пружину 18 от привода дроссельной заслонки, а другое - от  кор  11 электромагнита, под-, ключенного к выходу блока управлени  (на чертеже не показан), ко входу которого подключены датчики режимов работы двигател .Fuel from the tank (not shown in the drawing) via line 27 goes to pump 25, which through line 4 pumps fuel under a slight overpressure into chamber 5. The latter is maintained at a constant overpressure, for example, 0.15 atm using valve 26. From the chamber 5, the fuel through the gap between the saddle 8 and the metering body 7 enters the pipe 3, from which, displaced with air entering through the nozzle 24, is directed to the atomizer 22. The fuel-air emulsion leaving the atomizer 22 is mixed with air, passage u pipeline 1. The quantity and composition of the mixture entering the cylinders is determined by the opening of the throttle, the position of the accelerator pedal and the position of the metering body 7, which is determined by the amount of effort, one of which is transmitted through the spring 18 from the throttle actuator, and the other The core 11 of the electromagnet connected to the output of the control unit (not shown in the drawing), the input of which is connected to the sensors of the operating modes of the engine.

Дл  обогащени  смеси дозирующий орган 7 поднимаетс , обеспечива  увеличение проходного сечени  дл  топлива из камеры 5 в трубопровод 3. Так, например, при прогреве двигател  или при ускорении требуетс  обогащение смеси. Дл  этого через одну или несколько обмоток 16 электромагнита проходит ток, вследствие чего  корь 11 поднимаетс .To enrich the mixture, the metering unit 7 rises, providing an increase in the flow area for the fuel from chamber 5 to the pipeline 3. Thus, for example, when the engine is warming up or during acceleration, the enrichment of the mixture is required. To do this, a current passes through one or several windings 16 of the electromagnet, as a result of which the measles 11 rises.

обеспечива  подъем дозирующего органа 7, и смесь, поступающа  в цилиндры двигател , обогащаетс . Дл  обеднени  смеси питание током обмоток 16 уменьшаетс .by raising the metering body 7, and the mixture entering the engine cylinders is enriched. To deplete the mixture, the current supply of the windings 16 is reduced.

Таким образом, можно вли ть на состав смеси в зависимости от различных режимов работы, обеспечива  компенсацию, например изменение давлени  или влажности, атмосферного воздуха. Этим достигаетс  повышениеIn this way, it is possible to influence the composition of the mixture depending on various modes of operation, providing compensation, for example, a change in pressure or humidity, of atmospheric air. This increases

точности дозировани  подачи топлива и обеспечиваетс  повышение экономичности работы двигател  и снижение токсичности работы двигател .the accuracy of fuel metering and increases the efficiency of the engine and reduces the toxicity of the engine.
