LUBRICATING OF MACHINES OR ENGINES IN GENERAL; LUBRICATING INTERNAL COMBUSTION ENGINES; CRANKCASE VENTILATING

Introduced: September 1968

Description

F01M covers lubrication systems and components for machines and engines, including oil supply mechanisms, filters, and circulation equipment applicable across various engine types. Within internal-combustion engines, it addresses crankcase ventilation systems designed to manage blow-by gases and maintain proper pressure differentials. This subclass encompasses lubricant distribution methods, cooling systems integrated with lubrication, and components such as oil pumps, regulators, and splash lubrication systems. Related aspects of engine design covered in adjacent classes (F01B–F01N) address specific engine types and combustion processes, while general fluid handling appears in other F-series sections.
