摘　　要：由少量柴油引燃均匀天然气混合气,该种燃烧接近均质压燃燃烧过程,故可认为是准均质压燃过程。在发动机的最大扭矩转速下负荷特性的燃烧过程及排放物生成规律如何发展变化、具有何种特点,通过发动机缸内分析以及相应工况的排放测试,对发动机的各工况燃烧特性及对排放物生成的影响进行了研究。Since the homogeneous natural gasair mixtures ignited by a small quantity of diesel fuel will format a combustion proceeded in a similar way with the HCCI process, this combustion can be consider as a quasiHCCI process. By the approach of incylinder analyze and emissions comparison analyze conducted in different conditions, the trait of the combustion process displayed under the load characteristic in the case of maximum torque speed condition, along with the principles of emission's formation which described the character of the emission's formation process, will all be studied in this paper. Naturally, the effect of these combustion process and emission's formation process are also studied here through the same approach refered in above paragraphs.
