摘　　要：0引言 在全球汽车保有量不断攀升和排放法规日益严格的双重背景下,发动机的节能与减排越来越受到重视。开发清洁、高效的发动机技术也更具重要意义。由于采用压燃方式,混合气的空燃比不再受到混合气点燃和火焰传播的限制,内燃机的压缩比也不再受到爆震的限制。均质压燃（HCCI,Homogeneous Charge Compression Ignition）能使发动机同时保持更高的动力性能和燃油经济性,而且能有效降低发动机的NOx和PM排放。Homogeneous charge compression injection(HCCI) technology was introduced from three aspects as the characteristics of HCCI technology, its advantages and technical problems faced. The characteristics of HCCI combustion can effectively improve thermal efficiency of the engine, reduce emission of NOx and Soot. Its compatibility to fuel provides new idea for development of new energy engery. But at present, the HCCI is also confronted with the limitation of working area, difficult at cold startup and hard to control ignition timing.
