该论文已在赫尔辛基举行的第28届CIMAC世界大会上发表，论文的版权归CIMAC所有。 GE Transportation has launched an updated EVO diesel engine to meet the requirements of EPA Tier 4. The base engine with the largest production volumes continues to be the locomotive version of the 12 cylinder EVO rated at 3375 kW. Additionally, the L/V250 engine series has been developed to serve the marine market in variants from 6 to 16 cylinders. The EVO engine has been one of GE Transportation’s most successful products. Over 7500 engines have been built to date. The product line has been expanded from its original offering to serve higher power applications and the marine market via the L/V250 engine series. The new engines use cooled exhaust gas recirculation (EGR), 2-stage turbocharging, Miller valve timing, and highpressure common-rail fuel injection, along with sophisticated control strategies to achieve an "in-cylinder" solution. This approach meets the exhaust emission requirements while maintaining excellent fuel efficiency and provides a compact package with cost, installation and space advantages, since no exhaust after-treatment system is necessary. However, the "in-cylinder" approach imposes significant challenges for the engine designer. This paper will describe the combustion system configuration, performance parameters, along with some of the more challenging aspects of the mechanical design/development and field test experience.
