Experimental Evaluation of a Wall-Flow Filter for Gasoline Engine Particulate Emission Control 2001-24-0072

Motivated by the possibility of future emission regulations based on particle number as well as mass, after-treatment of ultrafine particles by a cordierite wallflow filter has been investigated. In a laboratory simulation, synthetic carbon particles of known size and concentration in air were captured with number-based efficiency exceeding 70% in the 20–100 nm size range. Effects of temperature, up to 400°C, filter loading time and ambient-temperature sample dilution have been quantified. Steady-speed and European drive cycle results for the same filter fitted to a passenger car with gasoline direct-injection engine have shown promising reductions in emissions, except at the highest speed of the cycle.
