EXHAUST SULFUR OXIDE MEASUREMENT USING AIR DILUTION

This paper describes a method for accurately measuring sulfur oxides in automotive exhaust. These studies have shown that: non-catalyst cars emit very low sulfates (less than 1% of fuel sulfur). Under some driving conditions, monolithic catalysts convert a major portion of the fuel sulfur to sulfates at concentrations close to thermodynamic equilibrium. Monolithic catalysts can store significant amounts of sulfates. Driving on a durability route discharges sulfur from the catalyst bed. /GMRL/
