柴油机电控共轨节能减排技术的探讨

摘要

Diesel engine technology has got great development in the recent half century, has been improved significantly in terms of performance measures. The paper reviewed the technology development of pressur-ized mechanical fuel system, cooling and electronic control of fuel injection, focuses on the role of techno-logical progress on diesel engine energy-saving emission reduction, and pointed out the advantages of the electronic controlled common rail system.%柴油机技术在最近半个世纪内取得了长足的发展，在性能指标方面有了很大程度的提升。本文对机械式燃油系统、增压中冷和电控喷油的技术发展进行综述，重点论述了技术进步对柴油机节能减排的促进作用，指出了电控共轨系统的优越性。
