Description
Изобретение относитс к области дизелестроении и может быть использовано в дизел х , оборудованных системой газотурбинного наддува с неременным давлением в выпускном коллекторе. В этих системах подвода газа к турбине производитс от нескольких цилиндров , имеющих последовательный выпуск, осуществл емый при помощи индивидуальных коллекторов, объединенных перед турбиной общим патрубом.The invention relates to the diesel engine industry and can be used in diesel engines equipped with a gas turbine supercharging system with a constant pressure in the exhaust manifold. In these systems, the gas supply to the turbine is made from several cylinders having sequential discharge, carried out with the help of individual manifolds, united in front of the turbine by a common patrub.
Недостаток известных систем заключаетс в том, что значительна часть энергии газа тер етс при расширении и неретекании его в коллекторы, в которых в этот момент отсутствует процесс выпуска.A disadvantage of the known systems is that a significant part of the gas energy is lost during expansion and non-flowing into the reservoirs, in which at this moment there is no release process.
Целью данного изобретени вл етс уменьшение нотерь энергии газа вследствие его перетекани из одного коллектора в другой путем установки на выходе из коллекторов в патрубок обратных клананов.The purpose of this invention is to reduce the notion of gas energy due to its flow from one manifold to another by installing a return clan at the outlet of the manifolds to the nozzle.
На чертеже показан вариант с пр моточнонластинчатыми обратными клананами. Коллекторы 1 и 2 присоединены к патрубку 3. В коллекторах и на входе в патрубок установлены обратные клапаны 4.The drawing shows a variant with a flow-wafer reverse clan. The collectors 1 and 2 are attached to the pipe 3. Check valves 4 are installed in the collectors and at the inlet to the pipe.
Предмет изобретени Subject invention
Вынускна система, нанример дл дизелей с переменным давлением газа перед турбонагнетателем , содержаща подключенные к общему патрубку коллекторы дл отвода газа из нескольких цилиндров, отличающа с тем, что, с целью предотвращени неретекани газа из одного коллектора в другой и уменьшени потерь энергии, коллекторы снабжены обратными клананами, например пр моточнопластинчатыми , установленными на входе в патрубок.A commercial system, for example, for diesel engines with variable gas pressure upstream of the turbocharger, contains manifolds connected to a common outlet for evacuating gas from several cylinders, characterized in that, in order to prevent gas from flowing out of one manifold into another and to reduce energy losses, the manifolds are inverse clans, for example, straight-plate, mounted at the entrance to the nozzle.
