ActiveReciprocating internal combustion engines—Exhaust emission measurement—Part 7：Engine family determination
往复式内燃机 排放测量 第7部分：发动机系族的确定
Application Summary AI generated
This standard specifies the criteria and procedures for grouping reciprocating internal combustion engines into families based on their emission characteristics, allowing for type-approval testing of a single representative engine. It is applied by manufacturers and regulatory bodies in the automotive, marine, and industrial equipment sectors to reduce the number of physical emission tests required for engine certification. The standard ensures compliance with emission limits while streamlining the approval process for engine variants sharing similar design and emission control features.
