1、I船舶柴油机电控装置设计摘要随着世界能源危机和环境污染的加重，人们的环保意识开始不断加强，于是日益严格的国际和地区性的环保法规便相继产生和出台了，保护环境的呼声也随之高涨。这就要求柴油机技术的不断发展进步，以达到符合人类及自然的需求的目的。20世纪70年代以来，伴随着电子控制技术的不断发展，而电子控制技术具有控制精度高、控制功能多、适应性强且调试方便、可以大幅度地降低柴油机的排放污染，同时提高柴油机经济性和动力性等一系列优点，于是我们将电子控制技术应用到柴油机，产生发展了电控柴油机。高压共轨电控燃油喷射系统作为一种高度柔性控制的燃油喷射系统，以其显著的优越性，已成为船舶柴油机技术发展的趋势之一
2、。本文应用电子控制技术，以高压共轨燃油喷射技术为基础，设计了一种电控装置,它自动检测排放物的成分及其含量，及时定量定时地控制喷射器喷射，以达到最佳燃油空气比和良好的雾化，实现船舶柴油机低燃油消耗，高动力性能及其废气的绿色无污染排放，达到国际环保法规要求。关键词：电控；柴油机；高压共轨；传感器IIAbstractAs the world energy crisis and environmental pollution increase, peoples environmental awareness began to strengthen, so increasingly stringent
