Abstract
Provided is an engine working apparatus capable of smoothly decelerating an engine. The engine working apparatus includes: an internal combustion engine including a piston reciprocally movable in a cylinder and a combustion chamber defined by the piston; an ignition plug configured to ignite air-fuel mixture in the combustion chamber; a detector configured to detect a rotation number of the internal combustion engine; and a controller configured to control an ignition timing of the ignition plug based on the detected rotation number, execute feedback control of determining the ignition timing based on a deviation between a target rotation number and the detected rotation number, and to execute the feedback control when the detected rotation number satisfies a predetermined deceleration condition.
