SAE J244 2011 Edition, June 1, 2011
Measurement of Intake Air or Exhaust Gas Flow of Diesel Engines
Includes all amendments and changes through Stabilization Notice (No longer revised / updated) , June 2011
Published By:SAE International (SAE)
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.
Purpose—This SAE Recommended Practice is intended to provide guidance for the proper measurement of combustion air flow into diesel engines as utilized in engine test cell environments.
