SPARKING PLUG IGNITED BY SEMI-SURFACE DISCHARGE, FOR INTERNAL COMBUSTION ENGINES, AND THE PROCEDURE FOR MANUFACTURING IT.

摘要

By unloading semi Surface Ignition type Spark plug for internal combustion Engines,It comprises: a tubular METAL BODY externally; an Insulating Element arranged in the body and has one end that protrudes axially Beyond the end of the body that use this back HOwards the combustion chamber; a Central electrode extends through the Insulating Element and axially protruding Beyond the end of the Insulating Element and electrodes connected to the Mass;End of the body, equidistanciados angularly and extending in the direction of the end of the central electrode protruding Insulating elementThe Ground electrodes being Molded or shaped so that its back towards the central electrode terminal surface is cut by the plane transverse to the Axis of the Spark Plug that is tangent to theThe Insulating Element protruding end of the central electrode; The Ground electrodes are composed of appendages of a welded Ring Element l end of the external metal body.
