（山摘要：与传统汽油机火花点火燃烧和传统柴油机压燃燃烧的燃烧方式不同，均质充量压燃燃烧（HCCI）是一种新的燃烧方式，由于其同时具有高热效率和低NOx排放的特点，已经成为发动机领域的一个重要研究方向。但是由于这种燃烧方式本身存在的一些问题，使其实用化推广受到了很大限制。本文主要介绍了当前HCCI燃烧面临的诸多挑战以及研究人员对其实用化推广所作出的努力。

    Abstract: Different from spark ignition combustion used in the traditional gasoline engines and combustion pressure combustion used in conventional diesel engines, Homogeneous charge compression ignition combustion (HCCI) is a new combustion mode. Because HCCI has characteristics like high thermal efficiency and low NOx emissions, it represents a trend of the engine researches. But, some problems existing in HCCI combustion limits its further applications . This paper mainly introduces current challenges from HCCI and the jobs that the researchers have made in promoting  the application of HCCI.
