摘要：

An experimental study was conducted on a common-rail diesel engine with 2, 5-dimethylfuran (DMF) addition of 0, 10% and 30% in mass respectively. The particle size distribution(PSD), geometric mean diameter(GMD), particles number and mass concentration were measured under different fuel injection timings. The results show that the particles emitted by the engine are dominated by nucleation mode(NM, particle size from 5 to 50 nm) regardless of injection timing and the amount of DMF addition. The particle size distributions present bimodal structure. With the retard of injection timing, the number of NM particles is increased first and then decreases. The variation tendency of accumulation mode(AM, particle size from 50 to 1 000 nm) particles number is irregular. The variation trends of total particles number and mass are consistent with the variation tendency of the NM number. The GMD of particles rises first and then declines. The DMF addition decreases the AM particles number, GMD and total partide mass, but increases the NM number and total particle number. The optimal operation scheme for this study is obtained at a DMF addition of 30% and an injection time of -10.0° CA ATDC. © 2018, Editorial Office of the Transaction of CSICE. All right reserved.
