Abstract

本实用新型涉及一种带有故障显示的汽车点火装置,其特征是在点火电路中接入发光二极管,可以随时随地跟踪点火系统是否正常工作,一旦发生故障,可根据二极管的显示状况判断故障所在,观测方便快捷,且使用元件少、安装简便。

Description

带有故障显示的汽车点火装置
本实用新型涉及一种带有故障显示的汽车点火装置。
点火装置是汽车发动机的重要部件,一旦出现故障,将影响发动机正常运转。点火装置一般均没有故障显示部分,判断故障发生部位则需借助其它仪器仪表。
本实用新型的目的在于提供一种带有故障显示的汽车点火装置。
本实用新型的带有故障显示的汽车点火装置包括点火开关、点火线圈、分电器和电源,其特征在于所述的点火线圈其低压线圈的输入端通过一只限流电阻与两只发光二极管的正极相连,两只发光二极管的负极一个接地,另一个与分电器中铂金触点的动点相连。接通点火系统电源后,接地的二极管发光,说明点火电流已送至点火线圈低压端,若不亮,则说明电源未接通。将点火开关旋至起动位置,发动机运转,与铂金触点相连的二极管一闪一闪地发光,则表明铂金触点工作正常,此时,若两只二极管亮度明显下降且一闪一闪也发光,则说明起动机电路有故障。
本实用新型的优点是可随时随地跟踪点火装置是否正常工作,一旦发生故障,可根据二极管的显示判断故障所在,观测方便快捷,使用元件少、可靠性强、安装简便。
图1是本实用新型的电路原理图。
实施例:参见图1,本实用新型包括电源1、点火开关2、点火线圈3、分电器4、限流电阻5和发光二极管6、7,限流电阻5一端与点火线圈的低压线圈输入端连接,一端与发光二极管6、7的正极连接,发光二极管6负极与分电器4的铂金触点的动点相连,发光二极管7负极接地。
