Effects of Combustion Modes on Exhaust Particle Size Distributions from a Diesel Engine Fueled with n-Heptane

Abstract

Abstract: Effect of combustion modes (including compression ignition direct injection (CIDI), homogeneous charge compression ignition (HCCI) and compound charge compression ignition (CCCI) combustion) on NSDs of exhaust particles from engines fuelled with n-heptane was studied. The results indicate that the structure of NSDs for n-heptane changes with premixed ratio（rp） obviously. The accumulation mode dominates in CIDI case. With the increase of rp, the accumulation mode decreases, the nucleation mode increases significantly. In HCCI case, the nucleation mode occupies the dominant part of the total particles, and the number concentration of accumulation mode is very low. And the total exhaust particles number concentrations for CCCI and HCCI are obviously higher than those of CIDI. In addition, the number concentration of nucleation mode is highly correlation with HC concentrations.

Key words: combustion mode, exhaust, ultrafine particle, n-heptane
