Embodiment Construction

[0035] Referring to the drawings-in which like reference numerals designate like or corresponding components throughout the several views, in accordance with the present invention, in Figure 1 to Figure 3 Reference numeral 10 in its entirety designates a spark plug, which is used in spark ignition applications, for example in internal combustion engines, to achieve ignition by means of a spark and to enable detection of the resulting combustion phenomena. The spark plug 10 can be used with various types and designs of internal combustion engines, including gasoline engines as well as engines powered by other hydrocarbon fuels such as E85, propane or the like. Spark plug 10 includes an insulator, generally indicated by reference numeral 12 , a housing, generally indicated by reference numeral 14 , and a center electrode assembly, generally indicated by reference numeral 16 . Housing 14 is advantageously fabricated from a steel alloy (eg, grade 1215 steel) or similar material, ...

Abstract

The invention relates to a spark plug (10) comprising an in-built combustion sensor. It comprises an assembly with a central electrode (16) with a connection stem (40) at one end and a central electrode (84) with a sparking surface at the opposite end; an overall tubular insulator (12) surrounding it; a casing (14) surrounding the insulator (12), a shell and a piezosensor assembly situated on theshell and comprising electrode contacts, a piezoelectric or piezoresistive element, an insulator and an upper socket attached to the shell. Field of application: Internal combustion engines, etc.

Description

technical field [0001] The present invention generally relates to devices that ignite by spark, such as spark plugs, and more particularly spark plugs with built-in combustion sensors. Background technique [0002] Spark plugs have been used for many years to provide an ignition means to ignite a mixture of hydrocarbon fuel and air within the combustion chamber of a controlled combustion internal combustion engine. In order to adapt to the special design and special environment of the engine, spark plugs come in many shapes. Spark plugs generally include a center electrode surrounded by an insulator held within and held by a metal body or housing. The housing typically has threads that mate with threads located in the cylinder head at a cavity called the spark plug well. Threads allow the spark plug to be screwed into the cylinder head by using conventional tools. In addition, the casing includes at least one ground electrode located on or extending from an end of the cas...
