TS ISO 7967-7

TS ISO 7967-7 is a vocabulary standard for the terminology used with governing systems in reciprocating internal combustion engines. Its purpose is to give a common technical language for the systems that regulate engine speed and power output under changing operating conditions. The document focuses on definitions, not on prescribing a control design or test procedure.

Why governing systems are treated as a distinct topic

In reciprocating engines, governing systems are associated with maintaining stable speed, managing load response, and keeping operation within the intended range. The subject covers a broad terminology base that may include mechanical, hydromechanical, electronic, or hybrid governing arrangements. A vocabulary standard helps engineers, manufacturers, and technical authors use these terms consistently in specifications, manuals, and engineering communication.

The technical frame covered by this part

• The scope covers definitions of terms relating to governing systems for RIC engines.
• It is a terminology document, not a design code for governing devices.
• As part of the ISO 7967 series, it supports a consistent vocabulary for engine components and systems.
• The terminology supports concepts such as speed sensing, command processing, and fuel or actuator influence at a general level.

For professionals working with engine control topics, this standard provides a shared basis for precise wording. Its main value is reducing ambiguity when the same governing concept appears in different documents, product literature, or technical discussions.
