Abstract

In the fuel property estimation apparatus of the invention, when fuel of an engine is cut, an upper-limit rotation speed NEmax is set based on vehicle speed SPD. When the engine rotation speed NE becomes equal to or less than the upper-limit rotation speed NEmax (YES in S102), the fuel injection for estimation of the cetane number of the fuel that is an index value the ignition quality of the fuel is implemented. The cetane number is estimated from the magnitude of engine torque produced by combustion of the injected fuel. By setting the upper-limit rotation speed NEmax to a smaller value as the vehicle speed SPD is higher, the apparatus restrains variations of the ignition delay time, and heightens the accuracy of the estimation of the cetane number.
