基于控制策略的某柴油机电磁离合水泵的开发与验证

摘要

Now the engine development tendency turns towards efficiency and energy conservation. This paper explains the switchable water pump consisting of its structure, principle and dominating strategy from the example of the intellective development of the cooling system for a diesel engine. Experimental comparison of the cooling systems makes it clear that the switchable water pump has an advantage over the traditional water pumps in some respects, such as better starting performance in cool engine, shorter time for heating engine, lower fuel consumption and emission improving.%为满足高效、节能发动机的开发需求，基于某柴油机冷却系统智能化开发，阐述电磁离合水泵的结构参数、工作原理、控制策略等，并通过冷却系统试验对比，表明使用电磁离合水泵具有冷启动性能好、暖机时间短、油耗降低、改善排放等优点。
