Description

(54) УСТРОЙСТВО ДЛЯ ИСПЫТАНИЯ ВЫПУСКНЫХ СИСТЕМ ДВИГАТЕЛЯ ВНУТРЕННЕГО СГОРАНИЯ НА ЭФФЕКТИВНОСТЬ ИСКРОГАШЕНИЯ(54) DEVICE FOR TESTING THE OUTLET SYSTEMS OF INTERNAL COMBUSTION ENGINE FOR THE EXTINGUISHING EFFICIENCY

корпуса 1 через дозатор 6. К дозатору 6 подключен также источник 7сжатого газа (баллон). Во внутренней камере 5 корпуса 1 выполнен эжекторhousing 1 through the metering device 6. A source of compressed gas (cylinder) is also connected to the metering device 6. In the inner chamber 5 of the housing 1 is made ejector

8и установлена топливна  форсунка8i installed fuel injector

9с регулировочным винтом 10. Форсунка 9 соединена с топливным баком .11 при трубки 12, котора  дл  обеспечени  предварительного подогрева топлива проходит вдоль стенки камеры 5. Топливный бак снабжен подкачивающим насосом 13, который создает в баке 11 повышенное давление.9c with an adjusting screw 10. The nozzle 9 is connected to the fuel tank .11 with a tube 12 which, to ensure the preheating of the fuel, passes along the wall of the chamber 5. The fuel tank is equipped with a booster pump 13, which creates an increased pressure in the tank 11.

Подача гранулированных частиц угл  во внутреннюю камеру 5 осуществл етс  через загрузочный резервуар 4 и дозатор б сыпучих материалов, например , барабанного типа, который подключен к камере 5 в промежутке между эжектором 8 и форсункой 9.The granulated particles of coal are fed into the inner chamber 5 through a loading tank 4 and a dispenser of bulk materials, for example, of a drum type, which is connected to chamber 5 between the ejector 8 and the nozzle 9.

При проведении испытаний выпускной системы две на эффективность искрогашени  в загрузочный резервуар 4 засыпают гранулированные частицы угл  размером 2,5-3,15 мм. Дозатор 6 дл  сыпучих материалов обеспечивает равномерную подачу определенного количества частиц угл  за определенный промежуток времени (8-10с).Зерна подаютс  в камеру 5 корпуса 1 в пространство между эжектором 8 и форсункой 9, где они смачиваютс  струей топлива из форсунки, а с помощью эжектора 8 смешиваютс  с воздухом, поступающим из баллона 7 сжатого воздуха. В камере 5 происходит нагрев и воспламенение частиц угл  и топлива. За тем сжатым воздухом гор ча  смесь выбрасываетс  в выпускной трубопровод 3. Давление сжатого воздуха должно превышать давление в выпускном трубопроводе . Количество подаваемого топлива в зависимости от типа двигател  и объема его выпускной систелел регулируетс  винтом 10.During the testing of the exhaust system two on the effectiveness of spark-burning, granulated particles of coal 2.5-3.15 mm in size are poured into the loading tank 4. The dispenser 6 for bulk materials provides a uniform supply of a certain amount of coal particles for a certain period of time (8-10s). The grain is fed into the chamber 5 of the housing 1 into the space between the ejector 8 and the nozzle 9, where they are moistened with a jet of fuel from the nozzle, and with the help of an ejector 8 are mixed with air from the compressed air cylinder 7. In chamber 5, the particles of coal and fuel are heated and ignited. Behind that compressed air, the hot mixture is discharged into the exhaust pipe 3. The pressure of the compressed air must exceed the pressure in the exhaust pipe. The amount of fuel supplied, depending on the type of engine and the volume of its exhaust system, is adjusted by screw 10.

Устройство дл  измерени  искр на выпуске фиксирует количество искр, прошедших черев искрогаситель.A device for measuring sparks on release records the number of sparks that passed through a spark arrester.

Таким образом, снабжение приспособлени  топливной форсункой, выполнение вытеснител  частиц в виде источника сжатого воздуха, св занного с резервуаром через дозатор, подключенного в свою очередь к камере через эжектор позвол ет автоматизировать процесс испытани  систем ДВС на эффективность искрогашени  и обеспечивает независимость результатов от субъективных качеств испытател . При этом становитс  возможным установление точных количественных соотношений между поданным количеством искр и количеством искр, прошедших через искрогаситель,что повышает точность измерений.Thus, supplying the device with a fuel injector, making the particle displacer in the form of a compressed air source connected to the reservoir through a metering device connected in turn to the chamber through an ejector allows automating the process of testing ICE systems for spark suppression and ensures that the results are independent of the testors' subjective qualities. . In this case, it becomes possible to establish accurate quantitative ratios between the supplied number of sparks and the number of sparks that passed through the spark arrestor, which improves the measurement accuracy.
