摘要： This fuel property estimation device is used in an internal combustion engine that uses a mixed fuel of three kinds of fuel and includes a first sensor that outputs a signal responsive to a physical property of the fuel in a fuel route and a second sensor outputs a signal responsive to an oxygen concentration of exhaust gas. This device measures a physical property value of the mixed fuel based on a first sensor signal, and calculates an air-fuel ratio value at stoichiometric combustion state using feedback of a second sensor signal. This device estimates a composition ratio of the mixed fuel based on the measured physical property value and the calculated air-fuel ratio value by referring to a relationship between the composition ratio of the mixed fuel and the physical property value and a relationship between the composition ratio of the mixed fuel and a theoretical air-fuel ratio value.
