Abstract: PROBLEM TO BE SOLVED: To improve reliability and accuracy of quality determination in the quality determination of fuel such as diesel fuel. SOLUTION: Values of an ignition delay and a flame spread rate regarding fuel to be determined are measured. If the measured value of the ignition delay falls within a range smaller than a reference line 71 or within a range greater than a reference line 72 as a first range according to the reference lines 71, 72 as first criterion for determining, it is determined whether or not the quality of the fuel to be determined is good based on good or poor quality of fuel determined by the first range. If the measured value of the ignition delay falls within a range from the reference line 71 to the reference line 72 as a second range according to the first criterion for determining, it is determined whether or not the quality of the fuel to be determined is good depending on whether or not the measured value of the flame spread rate falls within the range of a good-quality product according to a straight line 81 as a second criterion for determining.
