IGNITION (devices or installations peculiar to internal-combustion engines F02P; of cigarettes or tobacco A24F; compositions therefor, chemical igniters C06C); EXTINGUISHING-DEVICES

Introduced: September 1968

Description

Ignition and extinguishing devices for combustion apparatus, including spark plugs, igniters, pilot lights, and flame-initiation systems used in furnaces, boilers, engines, and other combustion equipment. Also covers fire suppression and extinguishing mechanisms integrated with combustion installations, as well as control systems for managing combustion startup and shutdown sequences. This subclass excludes general electrical ignition apparatus (covered in H05) and standalone fire-fighting equipment not directly associated with combustion apparatus.
