An engine device configured to include an engine, an exhaust gas purification device arranged on an exhaust path of the engine, and an engine control device that controls drive of the engine, configured to execute a plurality of regeneration controls with which particulate matter accumulated in the exhaust gas purification device is combusted and removed and configured to be mounted on a work vehicle, wherein as the plurality of regeneration controls, at least non-work regeneration control, in which an exhaust gas temperature is raised in combination of post-injection, a predetermined high rotational speed that is a parking maximum output and operating portions of the work vehicle are not driven, is included, and wherein the engine control device drives the engine so as to solely combust and remove the particulate matter in the non-work regeneration control and compulsorily executes isochronous control in which a rotational speed of the engine is maintained constant, irrespective of variation in load of the engine characterized in that at least stationary regeneration control that is executable when regeneration control fails during continuous work, and recovery regeneration control that is executable when the stationary regeneration control fails, are included in the non-work regeneration control, wherein when the engine control device executes any of the stationary regeneration control or the recovery regeneration control, the engine control device executes the compulsory isochronous control operation, and wherein the recovery regeneration control reduces the fuel injection amount of the post-injection compared with the stationary regeneration control. wherein as the plurality of regeneration controls, at least non-work regeneration control, in which an exhaust gas temperature is raised in combination of post-injection, a predetermined high rotational speed that is a parking maximum output and operating portions of the work vehicle are not driven, is included, and wherein the engine control device drives the engine so as to solely combust and remove the particulate matter in the non-work regeneration control and compulsorily executes isochronous control in which a rotational speed of the engine is maintained constant, irrespective of variation in load of the engine characterized in that at least stationary regeneration control that is executable when regeneration control fails during continuous work, and recovery regeneration control that is executable when the stationary regeneration control fails, are included in the non-work regeneration control, wherein when the engine control device executes any of the stationary regeneration control or the recovery regeneration control, the engine control device executes the compulsory isochronous control operation, and wherein the recovery regeneration control reduces the fuel injection amount of the post-injection compared with the stationary regeneration control. characterized in that at least stationary regeneration control that is executable when regeneration control fails during continuous work, and recovery regeneration control that is executable when the stationary regeneration control fails, are included in the non-work regeneration control, wherein when the engine control device executes any of the stationary regeneration control or the recovery regeneration control, the engine control device executes the compulsory isochronous control operation, and wherein the recovery regeneration control reduces the fuel injection amount of the post-injection compared with the stationary regeneration control.
