PRESSURE CHARGING SYSTEM FOR COMBUSTION ENGINE WITH CASCADE PRESSURE EXCHANGER

摘要

A pressure charging system of engine with cascade pressure exchanger has a cascade pressure exchanger with channel for discharge of compressed air connected to blow-off unit outlet branch pipe of which is equipped with cooler of supercharge air and connected by pressure circuit to inlet collector of the combustion engine. The blow-off unit is arranged as compressor placed on one shaft with turbine. In the pressure circuit a cooler of deep cooling is placed. Outlet tube of compressor is connected by bypass channel to inlet tube of the turbine outlet tube of which is connected to the deep cooling cooler.
