Abstract: 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.

The apparatus permits the opening timing to advance from the predetermined opening timing after the total intake air amount correlation value reaches the threshold after the engine operation starts.

Abstract: An object of the present invention is to estimate a viscosity of a fuel with high accuracy at all times, irrespective, for example, of fuel properties or conditions of deterioration with time. An internal combustion engine 10 includes a fuel pump 32 for supplying an injection valve with fuel in a tank 24. An ECU 40 detects a transition time t that begins when a drive signal is outputted to the fuel pump 32 and ends when the pump enters a steady operating state. At a start of the fuel pump 32, the higher the viscosity of the fuel, the longer the transition time t tends to be. The ECU 40 therefore detects the viscosity of the fuel based on a deviation ?t between the transition time t and a reference time t0.
