1 Scope

This part of GB/T 6809 defines the terminology of emission control systems for reciprocating internal combustion engines. ISO 2710-1 provides the classification of reciprocating internal combustion engines and defines the basic terms of this internal combustion engine and its operating characteristics. This section is classified according to the following terms. a) Exhaust emissions of pollutants; b) Emission control systems and devices; c) Emission control system parameters.

2 Normative references

The following documents are indispensable for the application of this document. For dated reference documents, only the dated version applies to this article Pieces. For undated reference documents, the latest version (including all amendments) is applicable to this document. GB/T 8190.1-2010 Emission measurement of reciprocating internal combustion engines Part 1.Test bench measurement of gas and particulate emissions (ISO 8178-1.2006, IDT) GB/T 8190.9-2017 Emission measurement of reciprocating internal combustion engines Part 9.Exhaust smoke measurement of compression ignition engines under transient conditions Test cycle and test procedure for test bench measurement (ISO 8178-9.2012, IDT)

3 Terms and definitions

3.1 Exhaust emission pollutants 3.1.1 Exhaust emission The discharge phenomenon of pollutants or similar pollutants contained in the exhaust gas of internal combustion engines. 3.1.2 Particulate matter; PM Particulates < General> Included in exhaust gas, particles mainly composed of soot and condensed hydrocarbons, sulfates and bound water. Note. When used in measurement and operating procedures, "particulate matter" is more accurately defined as "dilute the exhaust with clean filtered air, so that the air measured immediately upstream of the main filter paper When the body temperature is greater than 315K (42°C) and less than or equal to 325K (52°C), the substance collected on the specified filter medium", see 3.1 in GB/T 8190.1-2010. 3.1.3 Total suspended particulate; TSP Total suspended particulate matter The sum of particles (3.1.2) with a diameter of less than 100μm.
