Изобретение относитс к области машиностроени и может быть использовано в двигател х внутреннего сгорани .The invention relates to the field of mechanical engineering and can be used in internal combustion engines.
Из основного авт. св. № 306272 известна топливовпрыскивающа система дл двигател внутреннего сгорани , содержаща насос, соединенный с форсункой нагнетательным трубопроводом, в который включен аккумул тор, соединенный с нагнетательным трубопроводом двум каналами , в одном ив которых установлен регулируемый дроссель, а в другом - обратный клапан.From the main auth. St. No. 306272 is a well-known fuel injection system for an internal combustion engine, comprising a pump connected to a nozzle by a pressure pipe, which includes a battery connected to the pressure pipe by two channels, in one of which an adjustable choke is installed and in one another a check valve.
Недостатком известной системы вл етс невозможность регулировани параметров процесса впрыска топлива.A disadvantage of the known system is the impossibility of adjusting the parameters of the fuel injection process.
Целью изобретени вл етс улучшение процесса впрыска топлива в такой системе .The aim of the invention is to improve the fuel injection process in such a system.
Это достигаетс тем, что в нагнетательнслл трубопроводе между клапанами установлен дополнительный регулируемый дроссель, причем обратный клапан может быть выполнен регулируемым.This is achieved in that an additional adjustable choke is installed in the discharge pipe between the valves, and the check valve can be made adjustable.
На фиг. 1 схематично изображена предлагаема система; на фиг. 2 - график зависимости давлени впрыска Р„ от угла поворота коленчатого вала.FIG. 1 schematically shows the proposed system; in fig. 2 is a graph of injection pressure P „versus crankshaft angle of rotation.
Система содержит топливный насос 1 высокого давлени , соединенный с форсункой 2 впрыска топлива в цилиндр 3 двигател нагнетательным трубопроводом 4, в который включен аккумул тор 5, соединенный с нагнетательным трубопроводом двум каналами 6 и 7, в одном ив которых установлен регулируемый дроссель 8, а в другом - обратный клапан 9. В нагнетательном трубопроводе 4 между каналами 6 и 7 установлен дополнительный регулируемый дроссель 1О. Обратный клапан 9 выполнен регулируемым и снабжен регулировочным винтом 11, измен ющим усилие зат жки пружины 12 клапана. Аккумул тор 5 снабжен регулирующим устройством 13, которое может перемещать поршень 14 и измен ть объем аккумул тора 5.The system comprises a high pressure fuel pump 1 connected to a fuel injection nozzle 2 in a cylinder 3 of an engine by a discharge pipe 4, in which a battery 5 is connected, connected to the discharge pipe by two channels 6 and 7, in one of which an adjustable throttle 8 is installed the other is a check valve 9. In the discharge pipe 4 between the channels 6 and 7, an additional adjustable choke 1O is installed. The check valve 9 is adjustable and provided with an adjusting screw 11, which changes the pulling force of the valve spring 12. The battery 5 is provided with a regulating device 13, which can move the piston 14 and change the volume of the battery 5.
