Abstract
An engine device is equipped with an engine that is supplied with fuel from a fuel tank and that has a throttle valve arranged in an intake pipe, a supercharger that has a compressor arranged in the intake pipe, and an evaporative fuel treatment device that has a supply pipe for supplying evaporative fuel gas containing evaporative fuel generated in the fuel tank to the intake pipe in a region upstream of the compressor, and a purge valve provided in the supply pipe. Moreover, the throttle valve is controlled such that an opening degree of the throttle valve becomes larger when upstream purge for supplying evaporative fuel gas to the intake pipe via the supply pipe is carried out than when upstream purge is not carried out, while the supercharger is in operation.
