の吸気制御装置。 Each cylinder includes a first intake passage connected to the combustion chamber via the first intake valve, and a second intake passage connected to the combustion chamber via the second intake valve, and the second intake passage is connected to the combustion chamber via the second intake valve. An intake control valve is disposed in the intake passage of the first intake passage.
In an internal combustion engine in which an intake passage and a second intake passage are connected to a common intake passage and a throttle valve is disposed within the common intake passage, an accelerator sensor detects the amount of depression of an accelerator pedal and an output signal of the accelerator sensor. An intake control device for an internal combustion engine, comprising: a throttle valve drive device that controls opening and closing of the throttle valve based on the accelerator sensor; and an intake control valve drive device that controls opening and closing of the intake control valve based on the output signal of the accelerator sensor.
