Abstract
A control apparatus for an engine is configured to control the engine provided with: an exhaust-driven supercharger, provided with an adjusting mechanism which can change supercharging efficiency according to an opening degree, in an exhaust passage, and having a first control mode and a second control mode as a control mode of the adjusting mechanism, the first control mode allowing the opening degree to be maintained at a maximum supercharging efficiency opening degree at which the exhaust-driven supercharger has maximum supercharging efficiency without using a deviation between a target supercharging pressure and an actual supercharging pressure, the second control mode allowing the deviation to be fed back to the opening degree; and an electrically-driven supercharger driven by electric power supplied from a power supply. The control apparatus is provided with: a determining device configured to determine whether or not an electrified amount of the electrically-driven supercharger decreases; and a maintaining device configured to maintain the control mode in the first control mode before it is determined that the electrified amount decreases.
