TS ISO 7967-11

TS ISO 7967-11 is a vocabulary standard for the terms and definitions used in fuel systems of reciprocating internal combustion engines. As part of the broader ISO 7967 series on components and systems, it brings fuel-related concepts into a common technical language and distinguishes among fuel supply systems, carburetors, and fuel injection systems. In general technical use, such vocabulary helps keep engineering communication consistent across different engine types and system layouts.

How the fuel-system terms are grouped

The standard classifies the terminology into three main categories: fuel supply system, carburetor, and fuel injection system. This reflects the fact that fuel handling in engines can involve distinct functions, from transporting fuel to the engine, to preparing the fuel-air mixture, to delivering fuel under controlled conditions. In general technical context, carburetors are mechanical devices that mix air and fuel, while injection systems meter and deliver fuel under pressure; the fuel supply system refers to the supporting flow arrangement behind those functions.

Why this vocabulary matters in engine documentation

ISO 2710-1 provides the classification of reciprocating internal combustion engines and the basic terms and definitions for those engines and their characteristics, so this part is aligned with a wider engine terminology framework. TS ISO 7967-11 therefore supports consistent wording in technical documents, catalogues, training material, and engineering communication. This edition was withdrawn in 2022, but it remains useful as a reference for understanding the terminology of engine fuel systems.
