Abstract

A freezing dilution mini-tunnel method is described which allows sampling of diesel exhaust particulates with independent control of the diluted gas temperature T//d and collecting mesh surface temperature T//w. Particulates in the diluted gas caught on the cooled mesh surface kept at low temperature with liquid air at T//w. This tunnel was examined to determine the individual effect of these two operating variables T//c, T//w on the samples collected just behind an exhaust valve of a single-cylinder direct-injection test engine run at constant speed and load. Either decreasing diluted gas temperature or sampling mesh surface temperature resulted in an increase of a particulate diameter and coagulation of liquidwise particulates and cohesion of particulates.
