GB/T 17692-1999 in English

《GB/T 17692-1999汽车用发动机净功率测试方法》由TC114（全国汽车标准化技术委员会）归口，TC114SC16（全国汽车标准化技术委员会发动机分会）执行，主管部门为工业和信息化部。
本标准规定了汽车用发动机净功率测量方法。本标准适用于由制造厂提出M和N类汽车用发动机净功率相对于转速变化的曲线。本标准适用于往复活塞发动机(点燃式或压燃式)或转子发动机（点燃式或压燃式)，但不包括自由活塞发动机。

1 Scope

This Standard specifies the measurement methods of net power for automotive engine.
This Standard applies to the curve of net power of Categories M and N automotive engines relative to rotational speed change.
This Standard applies to reciprocating piston engines (spark ignition type and compression ignition type) or Wankel engines (spark ignition type and compression ignition type), but excludes free piston engines.
