AI Technical Summary

Problems solved by technology

In particular, during compression, the insulator may tilt in the plug body so that the insulator and plug body no longer run exactly parallel to each other
As a result, inaccurate positioning of the firing tip can result
In summary, for known spark plugs, there is a relatively large inaccuracy in the positioning of the insulator within the body of the spark plug

Embodiment Construction

[0026] exist figure 1 with figure 2 A spark plug 1 including a spark plug body 2 is shown in . The spark plug 1 , together with its spark plug body 2 , can be inserted in a manner known per se into the engine block of an internal combustion engine. The spark plug body 2 has a front end 3 and a rear end 4 . A ground electrode 5 is provided on the front end 3 extending into the engine in the operating state.

[0027] The spark plug 1 comprises an inner conductor 6 connected to an ignition tip 7 . An insulator 8 is arranged to surround the inner conductor 6 and includes a front end 9 and a rear end 10 . The ignition tip 7 is arranged on the front end 9 of the insulator 8 and together with the ground electrode 5 forms a spark gap 11 in which an ignition spark is to be generated in the operating state. The inner conductor 6 can be connected at the rear end 10 of the insulator to a supply line, not shown, in order to supply the spark plug 1 with the necessary ignition voltage ...

Abstract

What is described is a spark plug (1) comprising an inner conductor (6), an ignition tip (7) connected to the inner conductor (6), an insulator (8) surrounding the inner conductor (6) and having a front end (9) and a rear end (10), a spark plug body (2) having a front end (3) and a rear end (4), and at least one ground electrode (5) connected to the front end (3) of the spark plug body (2). The spark plug (1) has a longitudinal direction extending parallel to the inner conductor (6). The spark plug body (2) comprises a passage (12) extending in the longitudinal direction and in which the insulator (8) is disposed. A sleeve composed of metal is disposed between the insulator (8) and the spark plug body (2). The sleeve is tightly connected to the insulator (8) and the spark plug body (2) and is referred to below as the 'first sleeve' (13). At least one second sleeve (14) is disposed at a distance from the first sleeve (13) and, in fact, between the first sleeve (13) and the rear end (10) of the insulator (8). The second sleeve (14) is connected to the insulator (8) and touches the spark plug body (2) in the passage (12) thereof.

Description

technical field [0001] The present invention relates to a spark plug comprising an inner conductor, an ignition tip connected to said inner conductor, an insulator surrounding said inner conductor and having a front end and a rear end, a spark plug body having a front end and a rear end, and at least one connection with the spark plug body.
