摘要
与传统柴油机相比，电喷共轨柴油机之所以可以优化燃油喷射，降低燃油消耗；降低最小排烟量；降低氮氧化物排放量，主要是其喷射系统的改进。高共轨喷射压力，微机精确计算喷油量、喷射时间等优化方式，使共轨电喷柴油机无论在高、低负荷时都可以达到喷油雾化好， 燃烧充分的效果。然而，电喷共轨柴油机的发展时间不长，对柴油机管理人员来说，需要补充的知识和经验还很多。

Abstract
MAN L48/60Cr diesel engine is a new type of common rail electronic fuel injection four-stroke diesel engine, which is less assembled in domestic ships and less experienced in daily management and troubleshooting. The author briefly discussed the high pressure oil pump throttle valve management and maintenance, through his own experience of the fuel system fault analysis and treatment, in order to serve as a future manager of this kind of fault alarm and treatment methods for reference.
Key words： MAN L48/60CR；vessel；electronic fuel injection；diesel engine；throttle valve；High pressureoil pump
