Abstract:
1. An internal combustion engine comprising: a supercharger; a waste-gate valve provided with the supercharger; and a controller for controlling the waste-gate valve, said controller including a control logic to execute instructions from a non-transitory machine-readable storage medium to: (i) execute automatic stop control to bring the internal combustion engine to an automatic stop when predefined conditions are established during an operation of the internal combustion engine; (ii) control to place the waste-gate valve in an open position with a view toward decreasing a pumping loss of the internal combustion engine, in a case where a revolution speed of the internal combustion engine is equal to or higher than a self-recovery revolution speed at which the operation of the internal combustion engine is recovered by a resumption of fuel injection control without requiring auxiliary motive power generated when an operation resumption request concerning the internal combustion engine is generated in the middle of a stop period provided by the automatic stop control; and (iii) control to place the waste-gate valve in a closed position with a view toward increasing the pumping loss of the internal combustion engine, in a case where the revolution speed of the internal combustion engine is lower than the self-recovery revolution speed when the operation resumption request concerning the internal combustion engine is generated in the middle of the stop period provided by the automatic stop control.
