Measurement Precision Analysis on a Sampling System of Full-Flow Dilution Constant Volume
Abstract：The paper develops a Sampling System of Diesel Particulate Full-Flow Dilution Constant Volume.Its control precision is proved by using of the critical flow venturi nozzles to control the critical flow inlet conditions at constant values,where varied frequency Roots Blower provides power and exhaust temperature before the blower is controlled with pulse width method.Flow measurement precision is analyzed for the sampling system of full-flow dilution constant volume.Researches states that sampling system of full-flow dilution constant volume with venturi-nozzles achieves required measurement precision.
