Abstract

FIELD: engine engineering. SUBSTANCE: ring space of the fuel nozzle is in communication with the solenoid valve for supplying fuel and solenoid valve for supplying air. The valves are arranged at the top of the nozzle. There is an electronic system for control of the nozzle. Solenoid valve 4 supplies a batched amount of fuel to ring space 3 depending on duration of a pulse. On supplying a pulse to solenoid valve 5 for supplying air it opens and compressed air is supplied to ring space 3 entraining the fuel through spraying passageway 2 to the cylinder of an engine. In starting a time period during which the solenoid valve for supplying air is open is increased. EFFECT: enhanced reliability.

Изобретение относится к двигателестроению и предназначено для впрыскивания топлива в двигатель внутреннего сгорания, преимущественно дизель. Отличительными признаками предлагаемой топливной форсунки является то, что кольцевая полость соединена с электромагнитным клапаном подачи топлива и электромагнитным клапаном подачи воздуха, расположенными в верхней части форсунки. Для осуществления оптимального процесса впрыска и дозировки топлива применена электронная система управления форсункой. Электромагнитный клапан подачи топлива 4 подает в зависимости от продолжительности импульса дозированное количество топлива в кольцевую полость 3. При подаче импульса на электромагнитный клапан подачи воздуха 5 он открывается, и сжатый воздух подается в кольцевую полость 3, увлекая топливо через распыливающий канал 2 в цилиндр двигателя. В случае пуска двигателя время открытия электромагнитного клапана подачи воздуха увеличивается.The invention relates to engine and is intended to inject fuel into an internal combustion engine, mainly diesel. Distinctive features of the proposed fuel nozzle is that the annular cavity is connected to the electromagnetic fuel supply valve and the electromagnetic air supply valve located in the upper part of the nozzle. For the implementation of the optimal process of injection and fuel metering, an electronic nozzle control system is used. Depending on the duration of the pulse, the fuel solenoid valve 4 delivers a metered amount of fuel to the annular cavity 3. When a pulse is applied to the air supply solenoid valve 5, it opens, and compressed air is supplied to the annular cavity 3, dragging the fuel through the spray channel 2 into the engine cylinder. If the engine starts, the opening time of the air supply solenoid valve increases.
