Beschreibung
Zusammenfassung:	The present invention is directed to a piston arrangement with a unique bowl geometry for optimizing a two-stroke locomotive diesel engine having an exhaust gas recirculation ("EGR") system, This piston arrangement achieves a reduced level of smoke and particulate matter; promotes the mixing process in the engine cylinder; and provides a lower compression ratio for reducing NOx emissions. La présente invention porte sur un ensemble piston possédant une unique géométrie de cuvette destinée à optimiser un moteur diesel de locomotive à deux temps possédant un système de recirculation des gaz d'échappement (« EGR »). Cet ensemble piston permet d'obtenir un niveau réduit de fumée et de particules, il favorise le processus de mélange dans le cylindre du moteur; et il donne un rapport de compression abaissé pour réduire les émissions de NOx.
