往复式内燃机 排放测量 第8部分：发动机系组的确定
Application Summary AI generated
This standard specifies the methodology for grouping reciprocating internal combustion engines into families for exhaust emission testing and certification. It is applied by engine manufacturers and regulatory bodies to reduce the number of physical emission tests required, ensuring that engines within a group share similar emission characteristics. The standard is primarily used in the automotive, marine, and industrial machinery sectors for type-approval and compliance with emission regulations.
