Description
Изобретение относитс к области машиностроени . Известны устройства дл подвода отработанных газов двигател внутреннего сгорани к турбине, преимущественно к турбокомпрессору наддува , содержащие расположенную перед входным аппаратом турбины кольцевую полость и подсоединенные к ней свои ми минимальными сечени ми конические каналы, сообщеные с цилиндрами двигател 1. Однако в таких устройствах геометрические размеры проходных сечений кольцевой полости и конических каналов неоптимгшьны , что снижает эффективность использовани энергии отработанных га зов. Целью изобретени вл етс повышение эффективности использовани энергии отработанных газов. Это дос тигаетс тем, что в предлагаемом устройстве отношение площади поперечного сечени кольцевой полости в плоскости, проход щей через ее ось, к площади минимального сечени конического канала выбрано равным 3-4, На фиг. 1 представлена схема описываемого устройства; на фиг. 2 разрез по входному аппарату турбины. Каждый цилиндр 1 двигател внутреннего сгорани соединен с кольцевой полостью 2 при помощи выхлопных трубопроводов 3 с коническими каналами 4. Кольцева полость 2 размещена перед входным аппаратом турбины 5. При работе двигател выхлопные газы из цилиндров 1 поступают по выхлопным трубопроводам 3 в кольцевую полость 2. Тангенциальный под- вод газа в полость 2 создает в ней высокоскоростной поток, который эжектирует выхлопные газы из цилиндров 1. Давление газа в полости 2 имеет незначительные колебани , и газ поступает на входной аппарат турбины 5 единым неразделенным потоком. Оптимальный выбор отношени площади поперечного сечени кольцевой полости в плоскости, проход щей через ее ось, к площащи минимального сечени конического канала равным 3-4 позвол ет повысить эффективность использовани энергии отработанных газов.The invention relates to the field of engineering. Devices for supplying exhaust gases of an internal combustion engine to a turbine, mainly to a turbocharger of supercharging, are known, which contain an annular cavity located in front of the turbine inlet and connected to it by their minimum sections The sections of the annular cavity and the conical channels are not optimized, which reduces the energy efficiency of the waste gases. The aim of the invention is to increase the energy efficiency of the exhaust gases. This is achieved by the fact that in the proposed device the ratio of the cross-sectional area of the annular cavity in the plane passing through its axis to the minimum sectional area of the conical channel is chosen to be 3-4. FIG. 1 shows the scheme of the described device; in fig. 2 a section along the turbine inlet. Each cylinder 1 of the internal combustion engine is connected to the annular cavity 2 by means of exhaust pipes 3 with conical channels 4. The annular cavity 2 is located in front of the turbine 5 inlet. supplying gas to cavity 2 creates a high-velocity flow in it, which ejects exhaust gases from cylinders 1. Gas pressure in cavity 2 has slight fluctuations, and gas flows to the inlet apparatus rbina 5 single undivided stream. The optimal choice of the ratio of the cross-sectional area of the annular cavity in a plane passing through its axis to an area of the minimum section of the conical channel equal to 3-4 allows to increase the energy efficiency of the exhaust gases.
