INTERNAL-COMBUSTION PISTON ENGINES; COMBUSTION ENGINES IN GENERAL

Introduced: September 1968

Classification Context

Section:: MECHANICAL ENGINEERING; LIGHTING; HEATING; WEAPONS; BLASTING
Class:: COMBUSTION ENGINES; HOT-GAS OR COMBUSTION-PRODUCT ENGINE PLANTS
Subclass:: INTERNAL-COMBUSTION PISTON ENGINES; COMBUSTION ENGINES IN GENERAL

Description

F02B covers internal-combustion piston engines operating on the four-stroke or two-stroke cycle, including spark-ignition and compression-ignition (diesel) engines, as well as combustion engines in general. The class encompasses engine design, construction, and operational features such as cylinder arrangements, fuel injection systems, ignition mechanisms, supercharging, and cooling systems. Excluded are specific fuel supply systems (covered in F02M), engine control and fuel metering (F02D), and non-piston combustion engines like turbines (F02C).
