Product Description

Bag Mini Diluter

The Bag Mini-Diluter is an alternative to Constant Volume Sampling (CVS) Techniques and provides the improvements necessary to address the testing of Partial Zero Emission Vehicle (PZEV) and Super Ultra-Low Emission Vehicle (SULEV) emissions.  The differences between Bag Mini Dilute and CVS sampling are as follows:

  1. Sample is diluted with zero air – eliminates problems with ambient bags having higher concentration than sample bags.
  2. Dilution ratio is smaller – typically 5 to 1, making bag concentrations higher.

Features of Bag Mini Diluter

The drawing shows the key components that make up a Bag Mini Diluter system.  There are several critical factors for Bag Mini Diluter accuracy that must be understood.  They are:

  1. Accurate determination of critical flow venturi (CFV) flow-rates (dilution ratio).
  2. Achieve sonic flow on the CFVs.
  3. Maintain equal pressure and temperature for the sample and dilution CFVs.
  4. Accurate measurement of tailpipe exhaust flow-rate.
  5. Maintain proportionality of Bag Mini Diluter bag fill flow-rate to tailpipe exhaust flow-rate (requires an accurate determination of gas transport delay time).
