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.

Abstract: A control device of an internal combustion engine according to the present invention executes air-fuel ratio control based on an output of an air-fuel ratio sensor provided at an upstream side of a catalyst, with correction based on an output of an oxygen sensor at a downstream side of the catalyst. When it is determined that a degree of an output tendency in a predetermined lean region is not less than a predetermined lean degree, and that a degree of an output tendency in a predetermined rich region is less than a predetermined rich degree based on lean tendency and rich tendency values representing output tendencies of the oxygen sensor, a limit is set to the correction in a direction to more suppress enriching of an air-fuel ratio as a degree is larger in which the output of the oxygen sensor is shifted to a lean side.

Abstract: When engine is in the lean operation, and a WGV is fully closed, a boundary between a stoichiometric region and a lean region is corrected by learning using a turbocharging pressure obtained from a turbocharging pressure sensor. When the engine is in the lean operation, and the WGV is fully closed, the turbocharging pressure obtained from the turbocharging pressure sensor is equal to the actual maximum value of the engine torque output when a throttle valve is fully opened and the engine is in the lean operation, that is, the turbocharging pressure required to achieve the torque on the actual boundary. Therefore, the boundary can be brought close to the actual boundary by learning using the turbocharging pressure obtained from the turbocharging pressure sensor when the engine is in the lean operation and the WGV is fully closed.

Abstract translation: 当发动机处于稀薄运转状态并且WGV完全关闭时，通过使用从涡轮增压压力传感器获得的涡轮增压压力的学习来校正化学计量区域和贫气区域之间的边界。 当发动机处于稀薄运转状态并且WGV完全关闭时，从涡轮增压压力传感器获得的涡轮增压压力等于当节气门完全打开且发动机处于发动机时的发动机转矩输出的实际最大值 精益运转，即实现实际边界扭矩所需的涡轮增压压力。 因此，当发动机处于稀薄运转并且WGV完全关闭时，通过学习使用从涡轮增压压力传感器获得的涡轮增压压力，可以使边界靠近实际边界。
