A friction stir spot welding device (M) performs friction stir welding of an upper plate (31) and a lower plate (32). In a state where the pin (11) is retracted with respect to the upper plate front surface (31A), the controller (C) press-fits the shoulder (12) from the upper plate front surface (31A) to a predetermined reference position set with reference to the lower plate front surface (32A) at a first pressure, and then press-fits the shoulder (12) from the reference position to a press-fitting position deeper than the lower plate front surface (32A) at a second pressure. In a case where the hardness of the upper plate (31) is lower than the hardness of the lower plate (32), the first pressure is set to be lower than the second pressure, and in a case where the hardness of the upper plate (31) is higher than the hardness of the lower plate (32), the first pressure is set to be higher than the second pressure.

Combustion operation of an internal combustion engine (2) a series hybrid vehicle is automatically stopped and automatically restarted according to a power generation request. It is determined whether or not a catalyst temperature at the time of a restart request is equal to or higher than a predetermined activation temperature (S1, S2). If the catalyst temperature is equal to or higher than the activation temperature, substantially simultaneously with a start of motoring of the internal combustion engine (S9), fuel injection and ignition are started (S8). If the catalyst temperature is lower than the activation temperature, a valve timing is changed (S3) and a throttle valve opening is increased (S4) so as to increase volumetric efficiency, and the motoring is started (S5). When an elapsed time t from the start of the motoring reaches a required delay time tD (S6, S7), fuel injection and ignition are started (S8).

In this supercharging system, an exhaust passage forms a curve by means of an upstream part into which exhaust flows from a supercharger or a bypass passage, a curved part that changes the direction of the exhaust that has flowed into the upstream part, and a downstream part that connects the curved part and an exhaust purification catalyst. A waste gate valve has a bulging part that bulges into the bypass passage when the bypass passage is closed. The waste gate valve is configured to swing open so as to move away from the inner course of the curve, toward the downstream side, at the outlet of the bypass passage. Furthermore, the waste gate valve is configured to open within a range less than an angle at which the waste gate valve would become parallel to the central axis of the upstream part.
