710ECO Repower技术是美国EMD公司不久前专门针对自己早先制造的中低功率机车的升级改造而开发的,其核心部件包括久经考验的EMD710系列柴油机、EM2000微机控制系统及发动机自动起动和停机(AESS)系统等。采用710ECO Repower技术完成升级改造的机车比原型机车减少燃油消耗25%,减少机油消耗50%,减少排放70%,从而达到美国环保局的Tier2排放标准。文中简要介绍了710ECO Repower机车的设计特点和主要技术参数。 The 710ECO Repower technology was recently developed by the EMD company in the United States for the upgrading of low-power locomotives that it manufactured earlier. Its core components include the proven EMD710 series diesel engine, the EM2000 microcomputer control system, and the engine’s automatic start and stop (AESS ) System and so on. Locomotives upgraded with 710ECO Repower technology reduce emissions by 25%, reduce fuel consumption by 50% and reduce emissions by 70% compared to the prototype locomotive to achieve Tier 2 emission standards of the US Environmental Protection Agency. This paper briefly introduces the design features and main technical parameters of 710ECO Repower locomotive.
