PISTON ARRANGEMENT FOR A TWO-STROKE LOCOMOTIVE DIESEL ENGINE HAVE AN EGR SYSTEM

摘要

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.
