Claims

[Scope of utility model registration request]

Output increasing means for increasing engine output when a preset condition is satisfied during idling, and feedback correction and learning control based on the feedback correction so that the control result converges to the target result at least in the driving range including the above-mentioned idling. In the engine control device, the engine control device includes feedback control means for stopping feedback correction by the feedback control means after the engine output is increased by the output increase means and learning by the feedback control means is completed. An engine control device comprising:
