Abstract: PURPOSE:To prevent the mistake of learning from occurring by prohibiting the renewal of learning items computed in a specified operation condition if an engine is in the specified operation condition and the position of a timer is in the most delayed angle condition and is also in the condition where it needs to be delayed much more. CONSTITUTION:In a specified operation condition, a timing control valve 48 in an electronically controlled diesel engine 10 is controlled according to the deflection between the actual ignition timing due to an ignition timing sensor 38 arranged in the vicinity of a combustion chamber 10B and the target ignition timing computed by an ECU 56 on the basis of the outputs of an accelerator position sensor 20 and an engine revolution sensor 46. The position of a timer piston 42J is adjusted and the injection timing is thus controlled. On the other hand, in the condition other than the specified operation condition, the control valve 48 is controlled on the basis of the learning items computed at the time of controlling. In this case, if the timing position is in the most delayed angle condition and is also in the condition where it needs to be delayed much more at the time of the specified operation, the renewal of learning items can thus be prohibited.
