APPARATUS AND METHOD FOR CONTROLLING A FUEL INJECTOR UNDER ABNORMAL CONDITIONS

摘要

A control device (5) for an internal combustion engine including a fuel injection device (3) is provided. The fuel injection device (3) includes an injection hole (31b, 31c), and is configured to inject fuel from the injection hole (31b, 31c) into a combustion chamber (21). The control device (5) includes an actual injection amount output section (53), an injection amount deviation output section (51a), and an abnormality treatment direction section (51a). The injection amount deviation output section (51a) outputs a signal that indicates the deviation between an actual injection amount and a command fuel injection amount. The abnormality treatment direction section (51a) outputs a signal to enable treatment if the deviation exceeds a predetermined value.
