STARTING OF COMBUSTION ENGINES; STARTING AIDS FOR SUCH ENGINES, NOT OTHERWISE PROVIDED FOR

Introduced: September 1968

Classification Context

Section:: MECHANICAL ENGINEERING; LIGHTING; HEATING; WEAPONS; BLASTING
Class:: COMBUSTION ENGINES; HOT-GAS OR COMBUSTION-PRODUCT ENGINE PLANTS
Subclass:: STARTING OF COMBUSTION ENGINES; STARTING AIDS FOR SUCH ENGINES, NOT OTHERWISE PROVIDED FOR

Description

F02N covers systems, devices, and methods for initiating combustion in internal combustion engines, including starter motors, ignition systems, cold-start aids, and auxiliary starting mechanisms. This classification encompasses starter designs, starting fuel injection systems, pre-heating devices (glow plugs, block heaters), and mechanical or electrical starting aids that facilitate engine ignition under various operating conditions. Technologies addressing challenges specific to cold-weather starting, high-altitude operation, and rapid engine spin-up fall within this scope. Inventions related to engine starting that do not fit more specific combustion engine classifications are classified here as a catch-all provision.

Scope Notes

Application references: Starting of free-piston combustion-engines Starting of gas-turbine plants
