摘要： Disclosed is a control device that is for an internal combustion engine with a supercharger and capable of handling an operation resumption request during an internal combustion engine stop period in a situation where waste-gate valve control is exercised in consideration of pumping loss at the time of internal combustion engine stop. The internal combustion engine includes a turbocharger and a waste-gate valve. When the operation resumption request is generated while the internal combustion engine is stopped due to automatic stop control, the waste-gate valve fully opens as far as the engine speed is not lower than a predetermined revolution speed. Further, self-recovery control is exercised over the internal combustion engine (or more specifically, a fuel injection and ignition operation is resumed). Meanwhile, in a case where the engine speed is lower than the predetermined revolution speed when the operation resumption request is generated, the waste-gate valve fully closes. Subsequently, stop control, which has already been initiated, is continuously exercised to bring the internal combustion engine to a complete stop. The waste-gate valve reverts to an open position in preparation for the restart of the internal combustion engine.
摘要翻译： 公开了一种控制装置，其用于具有增压器的内燃机，并且能够在内燃机停止期间处理运行恢复请求，在考虑到泵送损失时执行废气阀控制的情况下 内燃机停机。 内燃机包括涡轮增压器和废气闸阀。 当由于自动停止控制而在内燃机停止时产生操作恢复请求时，废气门阀完全打开，只要发动机转速不低于预定的转速即可。 此外，在内燃机上进行自恢复控制（或者更具体地，燃料喷射和点火操作被恢复）。 同时，在产生运转恢复要求时发动机转速低于规定转速的情况下，废气门阀完全关闭。 随后，已经开始的停止控制被连续地进行以使内燃机完全停止。 废门阀回复到打开位置，以准备重新启动内燃机。
