Abstract The aim of this study was to evaluate the effect of polyoxymethylene dimethyl ethers (PODE)/diesel blends on particle size distribution and filtering efficiency of different modes of particulate matter (PM). The emission experiments were carried out on a diesel engine without any modification fueled with PODE/diesel blends by volume ratio of 0%, 10%, 20% and 30% respectively, and nitrogen oxide (NO_x) emission and particle size distribution were measured in the upstream and downstream of diesel particulate filter (DPF). The results showed that NO_x emission increased as the load conditions increased from 10% to 50%, while it showed a decline before it increased close to 100% load conditions. Meanwhile, the NO₂/NO_x ratio increased with the increasing blending ratio of PODE in the blended fuel under various loads, which indicated that PODE played a positive role in PM reduction. PODE/diesel blends ratio of 20% presented the best performance on PM reduction. Under 100% load condition, the total particle number and the particle volume concentrations with PODE/diesel blends ratio of 20% was decreased by 18.93% and 31.27% respectively compared with the pure diesel. Blending PODE in diesel showed negative effect on the PM reduction by DPF, especially under the load conditions of 10%~50%, but the overall filtering efficiency was still more than 95%.

Key words： polyoxymethylene dimethyl ethers emission particulate matter DPF filtering efficiency
