智能热管理:阀门关闭活塞冷却

皮尔博格有限公司开发了一种电磁阀,可根据需要关闭活塞的油冷却。这款产品今年将投入量产。

(PresseBox) (皮尔博格, )
为了冷却活塞,发动机油泵的油通过喷嘴注入活塞的内部冷却通道,从而消除多余的热量。新一代电磁阀接通后,可有目的性地截断流向这些喷嘴的油流。

这种关闭活塞冷却的方法具有以下优点:当发动机部分负荷运行时,不需要活塞冷却;而且在发动机泵中关闭油流后,可降低驱动功率,减少二氧化碳的排放。另一方面,在发动机的预热阶段,活塞可以更快地达到温度,从而也减少了未充分燃烧的烃(HC)的排放。

新一代电磁阀基于现有控制可变油泵的阀门开发而成。执行器的模拟辅助设计和优化的流动几何形状让新一代电磁阀变得特别小、特别轻,可以安装在油过滤器壳体内、发动机缸体内的很多位置。
