Описание (английский):

This document establishes a vocabulary for liquid fuel systems of reciprocating internal combustion engines. The terms and definitions are classified as follows: — fuel supply system (3.1); — carburettor (3.2); — fuel injection system (3.3). Note: ISO 2710-1 gives a classification of reciprocating internal combustion engines and denotes the basic terms and definitions of such engines and their characteristics.

Overview

ISO 7967-11:2022 is an international vocabulary standard for liquid fuel systems used on reciprocating internal combustion engines. It defines consistent terms and definitions for components and subsystems of fuel supply arrangements, with entries organized into three main classes: fuel supply system, carburettor, and fuel injection system. This second edition (2022) updates and expands the 2014 edition with revised and additional terminology to support clear technical communication across design, testing and regulatory contexts.

Key topics

Scope and structure

Establishes standardized vocabulary for liquid fuel systems (low‑ and high‑pressure supply, carburettors, injection).
Terms are classified under: fuel supply system (3.1), carburettor (3.2), and fuel injection system (3.3).

Core component definitions

Fuel supply elements: fuel pump, feed/priming pump, fuel filter, low‑pressure supply to high‑pressure generators.
Carburettor terminology: venturi (single, double, triple), float chamber, float, needle/needle valve, jets/gicleurs (main, idle, power, starting), throttle butterfly, enrichment devices, progression/idle circuits, and sizing terms (venturi diameter, throttle bore).
Fuel injection vocabulary: (classified in 3.3 - standard provides definitions to harmonize injector and system terms).

Technical clarifications

Includes illustrative figures (e.g., single and twin‑barrel carburettors) and cross‑references to related ISO documents (ISO 2710‑1 for engine classification).
No normative references are included; the document is a terminological reference rather than prescriptive test criteria.

Applications

ISO 7967-11:2022 is intended for professionals who need unambiguous terminology for design, manufacture, maintenance, documentation and regulatory work involving liquid fuel systems:

Engine and vehicle OEMs, component suppliers (carburettors, pumps, injectors)

Test laboratories, certification bodies and regulators

Technical authors, service manuals, repair shops and maintenance teams

Translators, standards writers and educators working on powertrain technology Using this vocabulary improves interoperability of technical documentation, parts catalogs, service instructions and compliance reports across international markets.
