摘要： It is possible to suppress fluctuations of an air intake amount when the open degree of an air intake control valve is unknown. An engine (200) includes an impulse valve (224) common to all the cylinders arranged in the engine (200). The impulse valve (224) is arranged in a communicating tube (206) provided at the downstream side of a serge tank (205). An ECU (100) executes impulse valve drive control. In the control, the ECU (100) judges whether a rotation angle sensor (225) which detects the open degree of the impulse valve (224) has failed. If it is judged that the rotation angle sensor (225) has failed, the ECU (100) controls a drive motor (224C) and a drive circuit (224D) for driving a valve body so that a valve body (224A) of the impulse valve (224) rotates inside the communicating tube (206). Here, the rotor of the drive motor (224C) which defines the rotation speed of the valve body (224A) has an rpm which is set in accordance with the mechanical rpm NE of the engine (200).
摘要翻译：当进气控制阀的开度未知时，可以抑制进气量的波动。发动机（200）包括设置在发动机（200）中的所有气缸共用的脉冲阀（224）。脉冲阀（224）配置在设置在淹没槽（205）的下游侧的连通管（206）中。 ECU（100）执行脉冲阀驱动控制。在该控制中，ECU（100）判断检测脉冲阀（224）的开度的旋转角度传感器（225）是否失败。如果判断出旋转角度传感器（225）发生故障，则ECU（100）控制用于驱动阀体的驱动电机（224C）和驱动电路（224D），使得冲击的阀体（224A）阀（224）在连通管（206）内旋转。在此，限定阀体（224A）的转速的驱动马达（224C）的转子具有根据发动机（200）的机械转速NE设定的转速。
