Description

Изобретение относитс  к машинострению , а именно двигателестроению и-, в частности, к устройствам дл  пода чй отработавших газов ДВС к турбоком прессору наддува.The invention relates to mechanical engineering, namely engine building and, in particular, to devices for supplying exhaust gases of the internal combustion engine to a turbo pressurization compressor.

Известны устройства, содержагйие выхлопную трубу, снабженную цилиндрическим участком с подключенными к нему суживающимис  выпускными патрубками по меньшей мере трех цилиндров, причем, оси выходных участков выпускных патрубков расположены под углом 20-45° к оси цилиндрического участка выхлопной трубы, а площадь: минимального сечени  каждого патрубка равна 0,45-0,7 площади поперечного сечени  цилиндрического участка p.J .Devices are known that contain an exhaust pipe provided with a cylindrical section with tapering exhaust pipes connected to it of at least three cylinders; moreover, the axes of the output sections of the exhaust pipes are at an angle of 20-45 ° to the axis of the cylindrical section of the exhaust pipe the nozzle is 0.45-0.7 for the cross-sectional area of the cylindrical portion pJ.

Недостатком,известных устройств  вл етс  повышенное гидравлическое сопротивление выпускных патрубков и соответствующее увеличение .потерь на пора потока выпускного газа двигател  внутреннего сгорани  из-за необходимости осуществить поворот указанного потока в указанных выпускных патрубках на угол 90° при малой длине патрубков, обусловленной ограниченными габаритами выпускных устройств двигателей внутреннего сгорани  транспортных установок.The disadvantage of the known devices is the increased hydraulic resistance of the exhaust pipes and a corresponding increase in the loss of exhaust gas flow time of the internal combustion engine due to the need to rotate the specified flow through the specified exhaust pipes at an angle of 90 ° with a small length of the exhaust pipes. internal combustion engine transport installations.

.Известны также устройства дл  под вода отработавших газов двигател  внутреннего сгорани  к турбокомпресрору наддува, содержащие выхлопную Трубу, к турбокомпрессору и снабженную пр молинейным цилиндрическим участком, и выпускные патрубки цилиндров , расположенные вокруг цилиндрического участка и подключенные своими выходными сечени ми к последнему под углом его оси со стороны противоположной плоскости входных сечеНИИ 2 .Also known are devices for the exhaust gas flow of an internal combustion engine to a turbocharger that contains exhaust pipe, to a turbo compressor and provided with a straight cylindrical section, and cylinder exhaust pipes located around the cylindrical section and connected by their outlet sections to the latter at an angle of its axis. from the opposite plane of the entrance section 2.

Однако, если угол наклона сечений к оси- цилиндрического участка не выполнен оптимальным, они имеют повы-шенное гидравлическое сопротивление и, следовательно, резко растут потери работоспособности выпускных газов в них.However, if the angle of inclination of the sections to the axis of the cylindrical section is not optimal, they have an increased hydraulic resistance and, consequently, the loss of efficiency of exhaust gases in them increases.

Цель изобретени  - повышение эффективности использовани  энергии выпускных газов.The purpose of the invention is to increase the energy efficiency of exhaust gases.

Поставленна  цель достигаетс  тем что угол наклона оси выходного сечени  каждого патрубка к оси цилиндрического участка выполнен в пределах от 18° до 1° .The goal is achieved by the fact that the angle of inclination of the axis of the output section of each nozzle to the axis of the cylindrical section is in the range from 18 ° to 1 °.

На фиг. 1 представлена принципиална  схема описываемого устройства, на фиг. 2 - устройство, общий вид в аксонометрии; на фиг. 3 - вариант исполнени  устройства с патрубком, изогнутым на угол около 90°/ на фиг. 4 - то же, с патрубком, изогнутым на угол около 180.FIG. 1 is a schematic diagram of the described device, FIG. 2 - the device, a general view in axonometry; in fig. 3 shows an embodiment of the device with a nozzle bent at an angle of about 90 ° (fig. 4 - the same, with a pipe bent at an angle of about 180.

Устройство содержит выхлопную трубу, снабженную цилиндрическим участком 1, с подсоединенными к нему выпускными патрубками 2 цилиндров Входные сечени  3 патрубков 2 расположены в одной плоскости и подключены к цилиндрам (не показаны), а выходные сечени  4 ориентированы в сторону турбокомпрессора (не показан ) и подключены к цилиндрическому участку 1. При этом, выпускные патрубки 2 расположены вокруг цилиндрического участка 1 и соединены с последним со стороны, противоположной входным сечени м 3. Оси выходных сечений 4 патрубков 2 наклонены к оси цилиндрического участка 1 под углом 5,.лежащем в интервале 18-1° и охватывают цилинлрический участок по дуге б 95-180° (фиг. 3 и 4).The device contains an exhaust pipe provided with a cylindrical section 1, with exhaust pipes 2 cylinders connected to it. The inlet sections 3 of the pipes 2 are located in one plane and connected to cylinders (not shown), and output sections 4 are oriented towards the turbo compressor (not shown) and connected to the cylindrical section 1. At the same time, the outlet nozzles 2 are located around the cylindrical section 1 and are connected to the latter from the side opposite to the inlet sections 3. The axes of the output sections 4 of the nozzles 2 are inclined the axis of the cylindrical portion at an angle of 1 5, .lezhaschem in the range of 18-1 ° and tsilinlrichesky cover portion along the arc b 95-180 ° (FIGS. 3 and 4).

Устройство работает следующим образом .The device works as follows.

Отработавшие газы из цилиндров двигател  поступают в выпускные патрубки 2, а затем в цилиндрический участок 1 выхлопной трубы и в турбину турбокомпрессора.The exhaust gases from the engine cylinders enter the exhaust pipes 2, and then into the cylindrical section 1 of the exhaust pipe and into the turbine of the turbocharger.

Нижний предел угла 5 (оС) обусловлен тем, что при Л « 1 гидравлический коэффициент сопротивлени  патрубков достигает своего минимума, который составл ет 0,08-0,1 в зависимости от условий компоновки конкретной конструкции выпускного коллектора.The lower limit of the angle 5 (° C) is due to the fact that at L "1" the hydraulic resistance coefficient of the nozzles reaches its minimum, which is 0.08-0.1 depending on the layout conditions of the particular design of the exhaust manifold.

Верхний целесообразный предел об 18 обусловлен тем, что уменьшение: о 18 даёт уменьшение гидравлического коэффициента сопротивлени  патрубков пор дка 0,06, что соответствует экономии расхода топлива 1-2 г/элсч.The upper appropriate limit of about 18 is due to the fact that a decrease of about 18 gives a decrease in the hydraulic resistance coefficient of the pipes of the order of 0.06, which corresponds to a saving in fuel consumption of 1-2 g / electr.
