IGNITION, OTHER THAN COMPRESSION IGNITION, FOR INTERNAL-COMBUSTION ENGINES; TESTING OF IGNITION TIMING IN COMPRESSION-IGNITION ENGINES

Introduced: September 1968

Classification Context

Section:: MECHANICAL ENGINEERING; LIGHTING; HEATING; WEAPONS; BLASTING
Class:: COMBUSTION ENGINES; HOT-GAS OR COMBUSTION-PRODUCT ENGINE PLANTS
Subclass:: IGNITION, OTHER THAN COMPRESSION IGNITION, FOR INTERNAL-COMBUSTION ENGINES; TESTING OF IGNITION TIMING IN COMPRESSION-IGNITION ENGINES

Description

F02P covers spark ignition systems and related control mechanisms for internal combustion engines, excluding compression-ignition diesel engines. This includes spark plugs, ignition coils, ignition timing control systems, and electronic ignition circuits used in gasoline and gas engines. The subclass also encompasses testing and diagnostic methods for verifying ignition timing accuracy in compression-ignition engines, which require specialized measurement techniques despite their self-igniting fuel mixtures. Adjacent diesel-specific technologies are classified separately under compression-ignition engine provisions.
