AUTOMOTIVE SULFATES--A CVS COMPATIBLE SAMPLING SYSTEM

This paper describes the development of a CVS compatible sampling system for automotive sulfate emissions. The design resulted from a consensus of ideas from EPA and industry. The system can be used with either a positive displacement pump or critical flow venturi CVS. A mist generator was developed to quantitatively inject sulfuric acid into the tunnel. While sulfate losses were acceptable using the mist generator, with actual automotive exhaust sulfate losses were much higher the reasons for these losses were investigated. Sulfate losses in the tubing between the car and sulfate tunnel were also investigated. /GMRL/
