标准摘要
[中文适用范围]： 本 SAE 推荐做法旨在为发动机测试室环境中使用的柴油发动机燃烧空气流量的正确测量提供指导。 [外文原描述]： This procedure establishes recommendations on the measurement of diesel engine intake air flow under steady-state test conditions. The measurement methods discussed have been limited to metering systems and associated equipment found in common usage in the industry, specifically, nozzles, laminar flow devices, and vortex shedding. The procedure establishes accuracy goals as well as explains proper usage of equipment. The recommendations concerning diesel engine exhaust mass flow measurements are minimal in scope.Cross Reference: ASME/PTC19.5:4,J177
