Product Code:SAE J1094
Title:Constant Volume Sampler System for Exhaust Emissions Measurement
Issuing Committee:Sae Ic Powertrain Steering Committee
Scope: This SAE Information Report describes uniform laboratory techniques for employing the constant volume sampler (CVS) system in measuring various constituents in the exhaust gas of gasoline engines installed on passenger cars and light trucks. The techniques described relate particularly to CVS systems employing positive displacement pumps. In some areas of CVS practice, alternate procedures are given as a guide toward development of uniform laboratory techniques.
