ABSTRACT:
An optimized two-stroke internal combustion diesel engine, suitable for locomotive applications, has been developed to meet the EPA locomotive Tier 2 emission standards. To achieve a low emission target below the EPA Tier 2 standards for NOx(5.5 g/bhp-hr) and particulates (0.2 g/bhp-hr), several innovative changes have been made to the engine. These changes include: a new piston bowl geometry; low oil consumption piston rings; optimized surface finish cylinder liner; optimized fuel injection camlobe; modified fuel injector nozzle; new efficient aftercooler; optimized oil separator; and optimized turbocharger.
