Description
(54) КАТАЛИТИЧЕСКИЙ ДОЖИГАТЕЛЬ(54) CATALYTIC ENDUGER
Известны каталитические дожигатели дл двигателей внутреннего сгорани , содержащие реактор с катализатором и эжектором вторичного воздуха.Catalytic burners for internal combustion engines are known, comprising a reactor with a catalyst and a secondary air ejector.
Предлагаемый каталитический дожигатель отличаетс от известных тем, что в нем на выходе из реактора установлена заслонка дл регулировани сопротивлени на выхлопном тракте, управл ема датчиком температуры , а в патрубке эжектора установлен датчик температуры или направлени потока.The proposed catalytic afterburner differs from the known ones in that a valve is installed at the outlet of the reactor to regulate the resistance in the exhaust path, controlled by a temperature sensor, and a temperature or flow direction sensor is installed in the nozzle pipe.
Такое выполнение позвол ет предотвращать перегрев дожигател , отключать последний при перегреве и получать сигнал об отключении .This embodiment allows you to prevent the afterburner from overheating, shut off the latter when overheated, and receive a shutdown signal.
На чертеже изображен предлагаемый дол{игатель .The drawing shows the proposed share.
В дожигателе после реактора 1 с катализатором на выхлопном тракте 2 установлена заслонка 3, которой управл ет датчик 4 температуры через управл ющий механизм.In the afterburner after reactor 1 with a catalyst in the exhaust duct 2, a valve 3 is installed, which is controlled by the temperature sensor 4 through a control mechanism.
На впускном тракте 5 дожигател установлен эжектор 6 вторичного воздуха, засасывающий воздух через патрубок 7, в котором установлен датчик 8.On the intake tract 5 of the afterburner, an ejector 6 of secondary air is installed, sucking in air through the pipe 7, in which the sensor 8 is installed.
Дожигатель работает следующим образом.The afterburner works as follows.
В зависимости от температуры отработавщих газов после реактора 1 будет мен тьс угол поворота заслонки 3, что изменит противодавление в дон игателе и, соответственно, приведет к уменьшению подсоса вторичного воздуха через эжектор 6, а следовательно, и выделению тепла в реакторе 1 дожигател .Depending on the temperature of the exhaust gases after the reactor 1, the angle of rotation of the valve 3 will vary, which will change the back pressure in the donor and, accordingly, will reduce the leakage of secondary air through the ejector 6 and, consequently, heat in the reactor 1.
В случае дальнейшего повышени температуры отработавших газов, что возможно при неработающей свече зажигани или попадании топлива в реактор 1, заслонка 3 полностью перекрывает выходное отверстие на выхлопном тракте 2, и отработавшие газы направл ютс в атмосферу через патрубок 7 эжектора G, о чем подает сигнал датчик 8.In the event of further increase in exhaust gas temperature, which is possible if the spark plug is inoperative or fuel enters reactor 1, valve 3 completely blocks the outlet in the exhaust path 2 and exhaust gases are directed to the atmosphere through the ejector nozzle 7 G, which signals the sensor eight.
