摘要： 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.

摘要： A target air amount for achieving a requested torque is back-calculated from the requested torque 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 operation in the first air-fuel ratio to operation in 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, the target air-fuel ratio is changed in accordance with an air-fuel ratio efficiency within the range from the first air-fuel ratio to the second air-fuel ratio. The air-fuel ratio efficiency is calculated based on a proportion of the requested torque relative to a torque that can be achieved by means of a current estimated air amount under the theoretical air-fuel ratio and the optimal ignition timing.

摘要： A control device for an internal combustion engine provided by the present invention is a control device which can enhance precision of realization of required torque while enhancing emission performance by positively changing an air-fuel ratio. The present control device generates a target air-fuel ratio by lessening a change speed of a required air-fuel ratio of an internal combustion engine. However, in a situation in which the required air-fuel ratio is made rich with return from fuel cut, lessening of the change speed of the required air-fuel ratio is stopped, and the required air-fuel ratio is directly outputted as a target air-fuel ratio. The control device calculates a target air quantity for realizing the required torque under the target air-fuel ratio. For calculation of the target air quantity, data in which relationship of torque generated by the internal combustion engine and an air quantity taken into a cylinder is fixed by being related to an air-fuel ratio can be used. The present control device manipulates an actuator for air quantity control in accordance with the target air quantity, and manipulates an actuator for fuel injection quantity control in accordance with the target air-fuel ratio.

摘要： A control apparatus of an internal combustion engine capable of appropriately reflecting various requests relating to the performance of the internal combustion engine. Specifically, the control device of the internal combustion engine acquires various requests relating to the performance of the internal combustion engine, and sets restricted ranges of the value of the control variable in accordance with the details of the requests. At this moment, the control device temporally changes the set restricted ranges for specific requests associated with the time integral value of the control variable rather than the instantaneous value of the control variable. Subsequently, the control device determines a final restricted range on the basis of the overlap between the restricted ranges set for each request, and determines the target value of the control variable in the final restricted range.

摘要： Disclosed is a control device that is used for an internal combustion engine and capable of making various requests concerning the performance of the internal combustion engine be reflected in a target control amount value while the requests need not be expressed in the form of a requested control amount value. The control device acquires various requests concerning the performance of the internal combustion engine and sets a request-specific constraint on a control amount value. More specifically, the control device expresses constraints to be set for control amount values as a set of constraint index values assigned to individual control amount values, and varies the distribution of the constraint index values assigned to the control amount values in accordance with the type of a request. Next, the control device integrates, for each control amount value, the constraint index values assigned to individual requests with respect to each control amount value. Then, in accordance with the distribution of the integrated constraint index value for a control amount, the control device determines a limitation of the control amount, which is defined by an upper-limit value and a lower-limit value. The control device determines a target control amount value within the determined limitation.

摘要： In a control of an internal combustion engine control apparatus, the control apparatus includes: a fuel tank that stores a fuel; a vaporized fuel tank that is connected to an intermediate portion of an intake passageway of an internal combustion engine and that stores a vaporized fuel that is formed by vaporization of the fuel; an in-tank fuel supply device that supplies the fuel from the fuel tank into the vaporized fuel tank; and a normally-closed vaporized fuel supply valve that opens and closes a connecting portion between the vaporized fuel tank and the intake passageway. The control apparatus estimates air/fuel ratio in the vaporized fuel tank, and produces the vaporized fuel in the vaporized fuel tank by driving the in-tank fuel supply device, with the vaporized fuel supply valve closed, until the estimated air/fuel ratio becomes substantially zero, during operation of the engine. At the time of starting the engine, the control apparatus supplies the vaporized fuel stored in the vaporized fuel tank into the intake passageway by opening the vaporized fuel supply valve.

摘要： An object of this invention is, with respect to a torque-demand-control type controller that subjects two kinds of actuators provided upstream and downstream in an intake passage to coordinated operations based on a requested torque for an internal combustion engine, to enable realization of a pulse-like torque change in a torque decreasing direction that is requested, for example, when performing an upshift operation in an electronically controlled automatic transmission. To achieve this object, according to a controller for an internal combustion engine of this invention, when a pulse component in a torque decreasing direction is included in a requested torque, a second requested torque that does not include the pulse component is generated. In this case, a first actuator provided on the downstream side in the intake passage is operated based on the requested torque. On the other hand, although a second actuator provided on the upstream side in the intake passage is operated based on the requested torque when there is not a valid value of the second requested torque, the second actuator is operated based on the second requested torque when there is a valid value of the second requested torque.

摘要： A target air amount for achieving a requested torque is back-calculated from the requested torque 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 being satisfied. After the virtual air-fuel ratio is changed, the target air-fuel ratio is maintained at the first air-fuel ratio until the ignition timing reaches a retardation limit. Subsequently, in response to the ignition timing reaching the retardation limit, the target air-fuel ratio is switched from the first air-fuel ratio to a third air-fuel ratio. After switching of the target air-fuel ratio, in response to a difference between the target air amount and an estimated air amount becoming equal to or less than a threshold value, the target air-fuel ratio is switched from the third air-fuel ratio to the second air-fuel ratio.
