国内外内燃机车技术水平的比较(上)

Comparison of engineering levels between foreign and domestic diesel locomotives

简要回顾了我国铁路牵引动力改革的成就 ;对国内外内燃机车的技术水平进行了比较。比较的重点是 :国内外机车车辆的运用强度 ;内燃机车的性能参数、经济性、可靠性和耐久性。对国内外内燃机车及内燃动车的主要部件和系统的技术水平进行了比较。比较的重点是 :柴油机、增压器、电传动系统、液力传动系统、走行部、辅助系统和微机控制系统。通过比较 ,找出国产内燃机车、内燃动车及其主要部件及系统与国外先进水平的差距。

The achievement of reforming railway traction power of China is reviewed.The engineering levels between foreign and domestic diesel locomotives are compared by laying stress on such aspects as operating strength,performance parameters,economic results,reliability and durability.The engineering levels of the main parts and systems between foreign and domestic diesel locomotives and diesel motor cars are compared by laying stress on such parts as diesel engine,turbocharger,electrical transmission system,hydraulic transmission system,running gear,auxiliary system and microcomputer control system.By comparing,the distance of engineering levels between foreign and domestic diesel locomotives and motor cars in terms of complete units and parts are pointed out.
