Abstract

A fuel quality evaluation apparatus and evaluation method enable a reliable evaluation at a low cost. The apparatus includes a combustion chamber which causes an injected fuel to combust, temperature control means which adjusts an interior temperature of the combustion chamber before injection, injection control means which controls the injection, light intensity measurement means which measures flame combustion light intensity, and analysis means which analyzes the measurement result and evaluates a fuel quality. The analysis means causes the fuel to combust a plurality of times, identifies a transformation of a flame light intensity, and evaluates the quality of the fuel based on a variation in the light intensity transformations for each combustion.
