    摘要: 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.

    摘要: An internal combustion engine control apparatus including an electronic control unit having a microprocessor and a memory. The microprocessor is configured to perform switching an injection mode between a first injection mode in which the fuel is injected in a range including an intake stroke and a compression stroke of an internal combustion engine and a second injection mode in which the fuel is injected in the range so that an injection frequency in the compression stroke in the second injection mode is greater than an injection frequency in the compression stroke in the first injection mode; and determining whether the injection mode needs to be switched based on an ignition timing of the ignitor.

    摘要: An internal combustion engine control apparatus is configured to control an internal combustion engine including a piston reciprocating in a cylinder and a fuel injector arranged to inject a fuel into a combustion chamber facing the piston in the cylinder. The internal combustion engine control apparatus includes an electronic control unit having a microprocessor and a memory. The microprocessor is configured to perform controlling the fuel injector so as to inject the fuel in an injectable area from a first crank angle at which an intake stroke is started to a second crank angle at which a compression stroke is ended, and setting an injection frequency of the fuel injected by the fuel injector in the injectable area. The microprocessor is configured to perform the setting including setting the injection frequency between once and four times.
