Abstract

The present invention is an exhaust gas recirculation system for a motor vehicle, having a turbocharger unit (18) which has a turbine (20) and a compressor (36), the compressor (36) having a compressor wheel (42) which rotates on an axis (66). There is also a dispersion apparatus (56) operably associated with a condensation separation apparatus (58). The condensation separation apparatus (58) separates moisture from exhaust gas flowing from the turbine (20), and the dispersion apparatus (56) reintroduces the moisture into the compressor (36) in proximity to the compressor wheel axis (66), preventing erosion of the compressor wheel (42).
