  • Patent number: 10378465
    Abstract: A fuel injection amount control device controls a fuel injection amount of an injector in an internal combustion engine including a blow-by gas ventilation system. The fuel injection amount control device includes a reflection rate setting section, a dilution correction section, and a dilution learning section. The reflection rate setting section sets a reflection rate proportional to the amount of a blow-by gas discharged to an intake air. The dilution correction section corrects a fuel injection amount by using, as a correction value, the product obtained by multiplying a reflection rate by a dilution learning value. The dilution learning section updates the dilution learning value such that an air-fuel ratio F/B correction value approaches 0 on the condition that a fuel dilution amount of engine oil is equal to or greater than a predetermined value.

  • Patent number: 10344695
    Abstract: An internal combustion engine operatively coupled with a variable load and an electronic control system operatively coupled with the internal combustion engine. The electronic control system is structured to receive an engine speed target value, a first engine speed feedback value, and a second engine speed feedback value. The electronic control system processes the first engine speed feedback value and the second engine speed feedback value to determine a feedforward correction value. The feedforward correction value is determined to correct for first variation between the second engine speed feedback value and the first engine speed feedback value due to variation in the variable load and to distinguish between the first variation and a second variation due to operation of the internal combustion engine.
