Abstract:
A fuel injection control apparatus including a microprocessor. The microprocessor is configured to perform calculating injection target values per a combustion cycle, controlling a fuel injector so as to inject fuel in accordance with the injection target values, instructing a switching between a first mode injecting the fuel and a second mode stopping the fuel injection, determining whether it is possible to inject the fuel in accordance with the injection target values when the switching from the second mode to the first mode is instructed, and modifying the injection target values by reducing a target injection frequency when it is determined to be impossible to inject the fuel in accordance with the injection target values, and the controlling including controlling the fuel injector, when the injection target values are modified, so as to inject the fuel in accordance with modified injection target values.
