Compared with GB/T 1883.2-2005, apart from structural adjustments and editorial changes, the main technical changes are as follows.

---Sixteen new basic terms have been added (see sections 3.1.1.1 to 3.1.1.9, 3.1.3.1 to 3.1.3.6, and 3.1.4);

---Two new terms related to maintenance procedures have been added (see 3.2.3 and 3.2.4);

---Ten new terms related to maintenance procedures have been added (see 3.3.2, 3.3.3, 3.3.5.1, 3.3.5.2, 3.3.6, 3.3.7, 3.3.13, 3.3.14).

3.3.16, 3.3.17);

---Added 24 terms related to engine malfunctions (see 3.4.1, 3.4.3, 3.4.4, 3.4.9~3.4.16, 3.4.21, 3.4.24~).

3.4.28, 3.4.30, 3.4.32, 3.4.33, 3.4.37, 3.4.38);

---Added 25 terms related to component failure (see 3.5.2~3.5.7, 3.5.9, 3.5.17, 3.5.20, 3.5.30, 3.5.32,...).

3.5.36, 3.5.38~3.5.41, 3.5.48, 3.5.49, 3.5.57~3.5.63);

---Two new terms have been added (see 3.6.1, 3.6.2) and three terms have been removed (see Chapter 7 of the 2005 edition) concerning liquid failure.

Introduction

Reciprocating internal combustion engines are widely used in various power machinery. To better promote trade, exchange, and technological cooperation, the International Organization for Standardization (ISO)...

The ISO has published and developed several terminology standards, which my country has adopted simultaneously, including those for reciprocating internal combustion engine components and systems.

Terminology standard GB/T 6809 (ISO 7967), terminology standard GB/T 1883 (ISO 2710) for the design and use of reciprocating internal combustion engines.

Meanwhile, in technical standards such as GB/T 21404 (ISO 15550), GB/T 21405 (ISO 14396), and GB/T 6072 (ISO 3046)...

The terminology related to the performance of reciprocating internal combustion engines has been defined.

GB/T 1883, "Glossary of Terms for Reciprocating Internal Combustion Engines," aims to establish a standardized document universally applicable to the design, operation, and maintenance of reciprocating internal combustion engines.

The terminology used is equivalent to ISO 2710.Depending on the stage of the reciprocating internal combustion engine, it consists of two parts.

---Part 1: Engine Design and Operation Terminology. The purpose is to define the basic terminology for the design and operation of reciprocating internal combustion engines.

---Part 2: Engine Repair Terminology. The purpose is to define the terminology related to the characteristics of engines and their components and repair activities, providing...

The document outlines terminology categorized by intended use and describes the faults leading to engine repair, along with the corresponding measures and procedures.
