  • Control device for internal combustion engine
    Patent number: 9650979
    Abstract: A target air amount for achieving a requested torque is back-calculated from the requested torque using a parameter that provides a conversion efficiency of an air amount to torque. The value of the parameter gradually changes to lower the conversion efficiency as the requested torque decreases from a second reference value towards a first reference value. The first reference value is calculated based on the engine speed. The second reference value is calculated based on an air amount with which the first reference value is achieved under a second air-fuel ratio, and a first air-fuel ratio. The target air-fuel ratio is set to the first air-fuel ratio when the requested torque is greater than the first reference value, and is switched from the first air-fuel ratio to the second air-fuel ratio when the requested torque decreases to a value equal to or less than the first reference value.

  • Control device for internal combustion engine
    Patent number: 9581094
    Abstract: A target air amount for achieving a requested torque is calculated from the requested torque by using a virtual air-fuel ratio. The virtual air-fuel ratio is changed from a first air-fuel ratio to a second air-fuel ratio in response to a condition for switching an operation mode from an operation by the first air-fuel ratio to an operation by the second air-fuel ratio being satisfied. After the virtual air-fuel ratio is changed from the first air-fuel ratio to the second air-fuel ratio, a target air-fuel ratio is switched from the first air-fuel ratio to the second air-fuel ratio. After the virtual air-fuel ratio is changed from the first air-fuel ratio to the second air-fuel ratio, a target valve timing is switched from a first valve timing to a second valve timing.

  • Control device for internal combustion engine equipped with supercharger
    Patent number: 9567923
    Abstract: A control device to detect abnormality of a supercharging pressure sensor accurately in an internal combustion engine equipped with a supercharger that can change a supercharging pressure by operation of an actuator. The control device operates an actuator so that a supercharging pressure measured by a supercharging pressure sensor becomes a target supercharging pressure, acquires a measured value of a flow rate of air flowing in an intake passage, and calculates an estimated supercharging pressure based on the measured air flow rate. The control device sets a first abnormality flag when a first simultaneous inequality is established, which is a simultaneous inequality evaluating magnitude correlation between the measured supercharging pressure, the target supercharging pressure and the estimated supercharging pressure, and is not established when the supercharging pressure sensor is normal.
