Spark plug for use in internal combustion engine, has plug body and mass electrode that are separated from each other as separate components before mounting plug in engine and are connected with each other in engine after mounting plug

摘要

The plug (1) has a spark plug body (2) and a mass electrode (3) that are separated from each other as separate components before mounting the plug in an internal combustion engine and are connected with each other in the combustion engine after mounting the plug. The mass electrode has a retaining unit (12), which is accommodated in a bore-hole (4) that is arranged in the internal combustion engine in a force-fitted manner. The spark plug body has a middle electrode (26), an insulator (27) and a housing (28) with an external thread. An independent claim is also included for a method for using a spark plug.
