Abstract: An engine device includes an engine including an in-cylinder injection valve and a spark plug, an exhaust gas control device, and a controller. The controller is configured to perform a last fuel injection from the in-cylinder injection valve in an expansion stroke and to set a fuel injection amount for the last fuel injection in expansion stroke injection driving, based on a coolant start temperature, post-start time, and volumetric efficiency. The expansion stroke injection driving is a control that is performed by performing the ignition by the spark plug in synchronization with the fuel injection in the expansion stroke.
