PROBLEM TO BE SOLVED: To provide a system for evaluating/analyzing engine oil consumption, configured to calculate engine oil consumption with high accuracy in a short time.SOLUTION: A temperature of an analysis part 22 of a sulfur analyzer 20 is adjusted before measuring sulfur concentration. The sulfur analyzer 20 having the analysis part 22 with adjusted temperature measures calibration gas G with sulfur of concentration corresponding to the sulfur concentration in exhaust gas. A standard curve S of the sulfur analyzer 20 is corrected on the basis of a result of measurement. The sulfur analyzer 20 with corrected standard curve S measures sulfur concentration in the exhaust gas. An interfering gas analyzer 40 measures concentration of interfering gas in the exhaust gas. On the basis of a measurement result of the interfering gas analyzer 40, the measurement result of the sulfur analyzer 20 is corrected. On the basis of the measurement result of the corrected sulfur analyzer 20, engine oil consumption is calculated. |
