摘要： A locomotive two-stroke uniflow scavenged diesel engine system including an exhaust gas recirculation (EGR) system is described for reducing NOx emissions and achieving improved fuel economy by recirculating exhaust gas through the engine. This system generally includes a turbocharger adapted to draw and compress fresh air. An aftercooler is coupled to the turbocharger adapted to cool the compressed air, A two-stroke uniflow scavenged diesel engine having a power assembly provides combustion and produces exhaust therefrom, The engine has a positive pressure gradient between the power assembly intake ports and the exhaust manifold to maintain scavenging and mixing in the power assembly. An EGR system includes a flow regulating device and a cooler. The flow regulating device is adapted to direct a select portion of the exhaust gas to be recirculated and direct the majority portion of the exhaust gas to the turbocharger. The cooler is coupled to the flow regulating device for decreasing the temperature of the exhaust gas. The flow regulating device controls the flow of cooled exhaust gas to be recirculated.
