    摘要: 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).

    摘要: The present invention is an exhaust gas recirculation (EGR) valve for an engine having an exhaust gas recirculation cooler operable for receiving exhaust gas from an exhaust, and delivering the exhaust gas to an intake. The present invention also includes an exhaust gas recirculation bypass passage operable for receiving exhaust gas from an exhaust, bypassing the exhaust gas recirculation cooler, and delivering the exhaust gas to an intake, as well as a single valve operably associated with the exhaust gas recirculation cooler and the exhaust gas recirculation bypass passage. The single valve is selectively operable for opening or closing flow from the exhaust to the exhaust gas recirculation cooler, the exhaust gas recirculation bypass passage, or both, the single valve also operable for metering flow therebetween.
