    • A method for the interpretive identification of a premature ignition in a combustion chamber of an internal combustion engine, wherein a feature (14, 16) which characterizes a combustion in the combustion chamber is determined and, on the basis of a parameter, a distinction is made between a normal combustion and a premature ignition by virtue of a threshold value (24) for the parameter being defined, which threshold value separates a first parameter range (18), assigned to a normal combustion, from a second parameter range (20), assigned to a premature ignition, and it is determined whether a value, assigned to the determined feature (14, 16), of the parameter lies in the first parameter range (18) or in the second parameter range (20), is characterized in that an adaptation for the threshold value (24) is performed by virtue of the interval between a value, assigned to a feature (14), of the parameter, which value lies in the first parameter range, and the threshold value (24) being determined, and an adaptation value (22) for the threshold value (24) being derived from said interval.
    • 一种用于在内燃发动机的燃烧室内的过早点火的解释性识别方法,worin的特征(14,16),其特征在燃烧室中的燃烧是确定性的开采和,一个参数的基础上,一个区别是 正常燃烧,并且由于该参数的阈值(24)的过早点火之间进行限定,其中阈值分离的第一参数范围(18),被分配给一个正常燃烧时,从第二参数范围(20) 中,分配给一个过早点火,并且它确定性开采无论的值,分配给所述第一参数范围(18)读出的参数的确定性开采特征(14,16)或在所述第二参数范围(20)的特征在于 为适应该阈值(24)的DASS借助于一个值之间的时间间隔进行的,分配给所述参数的特征(14),该值位于第一参数范围,以及阈值(24) 存在 确定性开采,以及适配值(22)为阈值(24)与所述间隔得到的。
