SOLUTION: When stopping fuel supply in engine speed reduction operation, cylinder pressure of the respective cylinders 1a is detected by a pressure sensor 50, and a cylinder pressure peak value is specified. The suction air volume is detected when stopping the fuel supply, and an allowable range is calculated on the basis of the suction air volume. When the cylinder pressure peak value exists in the allowable range, a determination is made that the cylinder-filled air volume of the cylinder coincides with the target volume. When the cylinder pressure peak value exists outside the allowable range, a determination is made that the cylinder-filled air volume of the cylinder deviates from the target volume, and an alarm device 55 is operated.

When the idle ON flag is ON and the simulated temperature of a catalyst arranged in an exhaust passage of the internal combustion engine exceeds a preset criterion (Fig. 2(A)), a catalyst deterioration inhibiting flag is set to be ON (Fig.2(C)) to prohibit deceleration F/C. When the catalyst deterioration inhibiting flag is ON, fuel pressure to be supplied to a fuel injection valve 24 is controlled to be higher than reference fuel pressure during normal operation (Fig. 2(E)).
