Abstract
本发明在蝶形阀段和电机端子之间设有一个适当的电连接部分,该部分可用于控制调整阀瓣,以便分流在进气管区中形成的静电荷,该进气管由塑料制造,并被用于内燃机中。
Description
本发明涉及一种具有至少部分由塑料制成的进气管的内燃机。
在内燃机中越来越多地使用这样的一种进气管,即在进气管区中设有一个蝶形阀,而蝶形阀部分上置有一调整阀瓣,以控制空气流量。调整阀瓣由一个电机控制,根据控制单元所确定的某些参数向电机提供激励电流,这样电机便可以按照初始的值设定阀瓣的位置。
上述结构中所产生的问题是在进气管区中会出现静电荷,特别是在进气管的塑料部分中会产生静电荷。这就会导致放电,即在由金属的蝶形阀段上放电,在这种情况下产生的电弧电压将对发动机的电器造成严重的影响。
在现有技术中,常用接地的方法来解决放电的问题,即通过设置与车体相连的金属带或金属网的办法分流静电荷。
本发明的任务是提供一种分流静电荷的简单的方法。
权利要求1给出了一种适用的解决上述问题的方案。
根据本发明,借助于至少一个具有导电性的连接部分可以分流所形成的静电荷,在上述情况下,该导线与电机的端子相连。这样就利用了电机低阻抗的控制方式,而且还利用了控制单元,特别是在控制单元中以最后级型式设置的火花制止器,从而减少因电机的高感应性而生产的电压峰值。
采用本发明的回路可在不增加***重量的情况下,以简单和良好的成本-效率的方式来抵消静电荷。
在本发明的一最佳实施例中,电机的两条供电线与蝶形阀段的外壁相连,这样可以减少一半的电势,并防止了由于天线效应而产生的高频问题。
下面将结合附图对本发明进行描述。
标号10示意性地表示了一根进气管,该进气管可以由塑料制造。进气管区10的下游处设有一蝶形阀段12,该阀以绝缘的方式安装且通常具有一个金属壳体。蝶形阀12设有一个调整阀瓣14,该阀瓣可以随轴16转动,从而打开或关闭该进气管10。调整阀瓣瓣4的轴16由一个电机18驱动。
电机18通过两个端子20和22提供电能,控制单元24示意性地表示了对电机18的控制,其控制元件构成了电子蝶形阀控制***或空载充气控制***的传统部分,它们并不是本发明的一部分。
在蝶形阀部分12的壁和与电机18相连的电线20、22之间装有电连部分30和26,这两个电连接部分均在电机18和蝶形阀12的壁之间提供了连接。
设置在电连接部分26或30中、且位于蝶形阀段12和电机端子20、22之间的电阻28和32可以确保不会在电机18的激励电流下产生短路。同样的电阻28和32可以使单元具有高阻抗性能。
在进气管区形成的静电荷可以由电连接部分26和30分流到电机端子20、22,这样可以由最后级以低阻抗的方式放电。如果在用于电机18的控制单元24的最后级中设置火花制止器就更好了,这样可以减小感应电压峰值;同时,所述的火花制止器也是消除静电电压峰值的一个有效工具。
由此,本发明可以用最少的电路元件来有效地分流静电荷。
