The purpose of the present invention is to provide an engine device capable of implementing a stable operation motion when switching from a gas mode to a diesel mode. An engine device 21 is provided with: an intake manifold 67 for feeding air into a cylinder 77; an exhaust manifold 44 for discharging an exhaust gas from the cylinder 77; a gas injector 98 for mixing a gaseous fuel into the air fed from the intake manifold 67; and a main fuel injection valve 79 for injecting a liquid fuel into the cylinder 77 and combusting the liquid fuel. When switching from a gas mode, in which a gaseous fuel is supplied into the cylinder 77, to a diesel mode, in which the liquid fuel is supplied into the cylinder 77, the time at which the liquid fuel supply starts is delayed relative to the time at which the gaseous fuel supply stops. |
