The report describes the experimental results of two techniques for the removal of particulate contaminants from spark ignition engine exhausts. The first technique was based on the thermal deposition of lead aerosol particles in the size range 0.1 - 0.8 microns in a packed bed. The effect of gas-packing temperature differential, packing material, packing shape and size, contamination buildup, and gas velocity on collection efficiency of the bed was studied. Experimental results show that collection efficiency of the packed bed device depends primarily on the gas-packing temperature differential. The second technique was based on the use of sonic waves to increase the collisions between the aerosol particles and the relatively coarse particles of a fluidized bed, and hence increase the collection efficiency. The effect of sound frequency, gas velocity, and power input to the sound driver units was studied. Experimental results showed that there was no significant effect of sound frequency, in the range 250-2700 HZ, on collection efficiency of the fluidized bed. (Author)
