摘要：本文通过梳理我国有关柴油机烟度排放方面的国家标准、行业标准及企业标准中的烟度单位，揭示了目前我国柴油机行业所用烟度单位多而混乱的状况，分析了其中哪种烟度测量方法合理，准确，更能真实地反映“烟度”，提出了一些涉及柴油机烟度排放的标准应尽快修订，统一采用“光吸收系数—m^-1”烟度单位之建议。

    Abstract:In this paper, by combing the smoke unit of our country national standards, industry standards and enterprise standards about the diesel engine smoke emission, reveals the smoke units currently used diesel engine industry in China is much and chaos of the situation, analyzed which kind of smoke measurement method is reasonable, accurate, and can truly reflect the "smoke intensity", put forward the advice: some involved diesel engine smoke emission standard in our country should be revised as soon as possible, to unified use the "light absorption coefficient - m^-1" smoke unit.
