Gas supply system i.e. exhaust gas recirculation system, for guiding gas to flow of another gas in internal combustion engine of e.g. lorry, has pipeline connected with another pipeline by inlet that is realized by annular gap

摘要

The system has a pipeline for guiding gas flow, and another pipe for supplying another gas flow. The latter pipeline is connected with the former pipeline by an inlet (30) such that the pipelines form a jet pump (1). The inlet realized by an annular gap (41) in the former pipeline. A supply device (60) is connected to the annular gap and designed in a spiral shape. A compressor for compressing air-exhaust gas mixture is arranged at an exhaust gas-air pipe (70) in downstream of a connection of an exhaust gas recirculation pipe (20). The recirculation pipe is connected to an air pipe (10). An independent claim is also included for a method for supplying gas to flow of another gas.
