Class:: MACHINES OR ENGINES IN GENERAL; ENGINE PLANTS IN GENERAL; STEAM ENGINES

Description

This class encompasses general-purpose machines and engines, including steam engines and their associated plant systems. It covers the fundamental mechanical principles, components, and operational characteristics of prime movers that convert energy into mechanical work, regardless of their specific energy source or application field. The class includes steam engine design, thermodynamic cycles, engine control systems, and supporting infrastructure for engine installations. Excluded are specialized engines and machines classified in more specific mechanical engineering classes (F02–F16) and applications requiring additional technical subject matter from other sections of IPC.
