ENGINE DEVICE

An engine device is provided with a fuel vapor processor comprising a first supply pipe configured to supply a vaporized fuel gas including fuel vapor generated in a fuel tank, to a downstream side of a compressor in an intake pipe; a first valve provided in the first supply pipe; a second supply pipe configured to supply the vaporized fuel gas to an upstream side of the compressor in the intake pipe; and a second valve provided in the second supply pipe. When a supercharger operates and the first valve is closed, the engine device performs abnormality diagnosis of the second valve, based on a control state of the second valve and a pressure in the fuel tank.
