Description
Изобретение относитс к машиностроению , а именно двигателестроени , и может быть использовано в выпускных системах двигателей внутреннего сгорани .The invention relates to mechanical engineering, namely engine building, and can be used in exhaust systems of internal combustion engines.
Цель изобретени - повышение эффективности путем согласовани nponyckHofi способности выпускной трубы с режимами работы двигател .The purpose of the invention is to increase efficiency by matching the nponyckHofi capacity of the exhaust pipe with engine operating modes.
На чертеже показана предлагаема выпускна система, общий вид.The drawing shows the proposed exhaust system, a general view.
Выпускна система содержит выпускную трубу 1, расширительную камеру 2, резонансный канал 3 и управл емую заслонку 4. Выпускна труба 1 подсоединена к цилиндру 5 двигател и к расширительной камере 2. Резонансный канал 3 подключен через входное отверстие б к выпускной трубе 1, выполнен с открытым торцом 7, и его открытый торец 7 помещен в расширительную камеру 2. Управл ема заслонка 4 установлена в открытом торце 7 резонансного канала 3 и подключена к приводу 8.The exhaust system contains an exhaust pipe 1, an expansion chamber 2, a resonant channel 3 and a controllable valve 4. The exhaust pipe 1 is connected to the engine cylinder 5 and to the expansion chamber 2. Resonant channel 3 is connected through the inlet b to the exhaust pipe 1, is open end 7, and its open end 7 is placed in the expansion chamber 2. The control valve 4 is installed in the open end 7 of the resonant channel 3 and is connected to the actuator 8.
Выпускна система двигател работает следующим образом.The exhaust system of the engine works as follows.
При увеличении частоты вращени вала двигател привод 8 переводит заслонку 4 в открытое положение. При этом выпуск отработавших газов из цилиндра 5 двигател происходит одновременно по выпускной трубе 1 и через входное отверстие 6 и открытый торец 7 резонансного канала 3 в расширительную камеру 2 и в атмосферу.When increasing the frequency of rotation of the motor shaft, the actuator 8 moves the valve 4 to the open position. When this exhaust gases from the cylinder 5 of the engine occurs simultaneously through the exhaust pipe 1 and through the inlet 6 and the open end 7 of the resonant channel 3 into the expansion chamber 2 and into the atmosphere.
На низких и средних частотах вращени вала двигател заслонка 4 устанавливаетс приводом 8 в закрытое положение. В этом случае отработавшие газы из цилиндра 5 проход т по трубе 1 непосредственно в расширительную камеру 2, а также заполн ют объем резонансного канала 3, в котором формируютс волны давлени , повышающие эффективность выпускной системы.At low and medium frequencies of rotation of the motor shaft, the valve 4 is set by the actuator 8 to the closed position. In this case, the exhaust gases from cylinder 5 pass through pipe 1 directly into the expansion chamber 2, and also fill the volume of the resonant channel 3, in which pressure waves are formed, increasing the efficiency of the exhaust system.
