Изобретение относитс к машиностроению , а именно к двигателестрое- нию, в частности к системам выпуска.FIELD OF THE INVENTION The invention relates to mechanical engineering, in particular to engine building, in particular, exhaust systems.
Цель изобретени - обеспечение повышени экономичности двигател путем улучшени наполнени цилиндров свежей рабочей смесью.The purpose of the invention is to provide an increase in engine efficiency by improving the filling of the cylinders with fresh mixture.
На фиг.1 показана схема системы выпуска; на фиг. 2 - разрез по выпуск- ю ью. ному каналу в головке цилиндра двигател .Figure 1 shows the scheme of the exhaust system; in fig. 2 - section by issue. to the duct in the cylinder head of the engine.
Система содержит выпускной трубопровод 1 и подключенные к нему криволинейные выпускные каналы 2, выпол-15 двигател внутреннего сгорани , сопают в выпускной канал 2. Образующийс на поверхности канала 2 пограничный слой отсасываетс через щель 7 в полость 8 и из нее через эжектор 9 в выпускной трубопровод 1 , что способствует уменьшению сопротив лени выпуску газов и не ухудшает на полнени цилиндра свежей рабочей смеThe system contains an exhaust pipe 1 and curved exhaust channels 2 connected to it, made of an internal combustion engine, are pulled into the exhaust channel 2. The boundary layer formed on the surface of channel 2 is sucked out through the slit 7 into the cavity 8 and from it through the ejector 9 into the exhaust pipeline 1, which helps to reduce the resistance to the release of gases and does not affect the filling of the cylinder with a fresh working mixture.
