GLOSSARY OF TERMS
Introduction
This glossary of terms is intended to cover both general and emissions-related (to SAE J 1930) terminology. It is in- tended to enable the user to ascertain the meaning of standardized terms and acronyms used throughout the Manual.
The required term may be looked-up in the left-hand column, and subsequent columns give the standard abbreviation
or acronym, definitions and previously used terms, as applicable.
As this Manual is a world
-wide publication, and must comply with certain Society of Automotive Engineers Standards, it has been necessary to adopt the terminology etc. demanded by that Standard.
