TS ISO 7967-11

TS ISO 7967-11 is a vocabulary standard for the terms and definitions used for liquid fuel systems in reciprocating internal combustion engines. It focuses on giving common technical names to the parts and functions involved in storing, preparing, and delivering liquid fuel to the engine. As a vocabulary document, it does not set out new performance requirements; instead, it supports clear and consistent technical communication.

How the liquid-fuel terminology is organised

The document classifies its terms into three main groups: fuel supply system, carburettor, and fuel injection system. This distinction matters because it separates the overall fuel-delivery architecture from the specific way the fuel-air mixture is formed. In general technical terms, a fuel supply system is the broader framework covering storage, transfer, filtration, and feed functions. A carburettor refers to a traditional arrangement in which fuel is mixed with the incoming air by mechanical means, while a fuel injection system describes a more controlled approach in which fuel is metered and delivered under pressure to the relevant point.

Why this vocabulary matters in practice

A terminology standard like this helps keep design documentation, maintenance literature, training material, and technical publications aligned so that the same term is not used inconsistently for different equipment. Because reciprocating internal combustion engines are used in many applications, liquid fuel systems vary with engine design and fuel type; this standard provides a stable naming structure for that field. The note referencing ISO 2710-1 points to the broader classification of reciprocating internal combustion engines and the basic terms and characteristics of those engines.
