Nano-Particles is main subject in health effect. The relationships between transient vehicle operation and nano-particle emissions are not well-known, especially for diesel passenger vehicle with DPF. In this study, a diesel passenger vehicles were measured on a chassis dynamometer test bench with and without DPF regeneration. The particulate matter (PM) emissions of these vehicles were investigated by number, size and mass measurement. The mass of the total PM was evaluated using the standard gravimetric measurement method, the total number and size concentrations were measured on a NEDC driving cycle using Condensation Particle Counter (CPC) and EEPS. Total number concentration by CPC was 1.5×10¹¹N/㎞ and was 20% of result by EEPS. This means about 80% of total particle emission is compromise of volatile and small-size particle(<22㎚). In regeneration, particle emission was 6.2×10¹²N/㎞ and was emitted 400 times compared to without regeneration. and particle of 22~100㎚ size was emitted mainly, showed peak value nearby 40㎚ size. This means regeneration decreased mean size of particle. In before and after regeneration, PM showed no change but particle number showed about 6 times difference. The regeneration influence on particle number emissions is believed to be related to DPF-fill state and filtration efficiency.
