    摘要:

    利用TSI EEPS3090微粒粒度測試系統(tǒng),，試驗研究了高壓共軌柴油機燃用不同理化特性調(diào)和柴油時的微粒成分及微粒排放粒度分布特征,，揭示了燃料著火性能及燃料組分對微粒排放特性的影響規(guī)律。研究結(jié)果表明,，對于不同著火性能的燃料,，中小負荷工況下微粒數(shù)量濃度分布曲線大致呈單峰結(jié)構(gòu)，峰值位于30nm附近,，排氣中絕大多數(shù)微粒粒徑處于5~300nm之間,。適當(dāng)提高燃料十六烷值，能夠縮短滯燃期,，增大擴散燃燒期比例,，有助于減少核態(tài)微粒的排放數(shù)量。同時,，燃料含硫量對核態(tài)微粒排放影響較大,，含硫量高將導(dǎo)致核態(tài)微粒排放量增加。隨十六烷值增加,，排氣微粒中可溶性有機物質(zhì)（SOF）比例減小,，干碳煙（DS）比例上升,。

    Abstract:

    Tests were conducted by using TSI EEPS3090 particle size spectrometer to study the effect of fuel with different physical and chemical properties on particle size distribution in common rail diesel engine. For the fuels of different cetane number, the particle size was mostly between 5nm and 300nm and the particle size distributions were unimodal with peaks at 30nm with medium or small load. Increasing cetane number appropriately could make the ignition delay period shorter and the sustained combustion period longer, which would drop the number of nuclei mode particles. Meanwhile，the number of nucleation mode particles increased with more sulphur in the fuel. With the cetane number increased, the percentage of SOF decreased and the percentage of DS increased.
