Exhaust gas fraction recycling device for e.g. oil engine, has exhaust gas intake duct emerging at intake point, and integrated to structure of compressor to form even and unique block with compressor, outer gas intake duct and outlet duct

摘要

The device has an outer gas intake duct (2) for inletting outer gas into a compressor (1), and an outlet duct (5) for releasing the gas compressed by the compressor towards an internal combustion engine. An exhaust gas intake duct (3) is arranged in a manner to emerge at the level of an outer gas intake point in the compressor for mixing a recuperated fraction of an exhaust gas of the engine with the outer gas. The exhaust gas intake duct is integrated to the structure of the compressor for forming an even and unique block with the compressor and the ducts (2, 5).
