Abstract
The diesel particulate filters have been developed to remove diesel particles known to have adverse health effect from the automotive emission. Understanding of the phenomena of diesel exhaust in an exhaust pipe is needed in designing a DPF. In this study, the phenomena of diesel exhaust in an exhaust pipe were simulated by using combustion aerosols. The test aerosols were generated from a combustion aerosol generator consisted of a burner and a dilution unit. Temperature in an exhaust pipe was constantly controlled by using a heating tape. Particle size distributions were measured by a scanning mobility particle sizer. The particle formation and growth will be discussed.
