| 摘要 |
The present invention relates to a method of measuring engine oil deterioration, including measuring the first absorbance of engine oil using near infrared at a wavelength of 1000 nm or more, measuring the second absorbance of the engine oil during use using near infrared at the wavelength, and comparing the first absorbance and the second absorbance of the engine oil, so that the engine oil may be determined to be in a state of deterioration when the second absorbance may be at least 1.5 times the first absorbance, and to a system for measuring engine oil deterioration therefor. |
