摘要： An internal combustion engine control apparatus includes a secondary air supply device having a secondary air supply passage that supplies secondary air pumped by an air pump into an exhaust system of an internal combustion engine and an opening/closing unit that opens and closes the secondary air supply passage. A controller provided in the internal combustion engine control apparatus sets the opening/closing unit in an open condition such that the secondary air is supplied to the secondary air supply passage, and then executes foreign matter removal control in which the opening/closing unit is opened and closed. As a result, foreign matter caught in an ASV during AI control is removed immediately. By implementing OBD after removing the foreign matter, detection of an open sticking abnormality caused by foreign matter caught in the ASV is suppressed.

摘要翻译： 内燃机控制装置包括二次空气供给装置，该二次空气供给装置具有二次空气供给通路，其将由空气泵泵送的二次空气供给到内燃机的排气系统中，以及打开/关闭二次空气供给的打开/关闭单元 通道。 设置在内燃机控制装置中的控制器将打开/关闭单元设置在打开状态，使得二次空气被供给到二次空气供给通道，然后执行打开/关闭单元打开的异物去除控制 并关闭。 因此，AI控制期间陷入ASV的异物被立即取消。 通过在去除异物之后实施OBD，抑制由ASV中捕获的异物引起的开放粘连异常的检测。
