摘要： A fuel supply amount control apparatus for an internal combustion engine uses an idling control amount QISC obtained by reducing an idling control amount Qa by an idling control amount correction value KQISC, when determining the amount of fuel injected for the lean combustion when the vehicle is running. Therefore, during the lean combustion with the D range is selected, there is substantially no difference between the road load amount of fuel injected during the idling state and the road load amount of fuel injected during a low-speed running of the vehicle. Hence, an increase in the amount of fuel injection during the low-speed running of the vehicle based on the lean combustion achieved upon a fuel increase request does not result in an excessively great output torque of the engine, so that the low-speed running of the vehicle becomes stable and good drivability can be maintained.
摘要翻译：一种内燃机的燃料供给量控制装置，在确定在车辆行驶时为稀薄燃烧喷射的燃料量时，使用通过怠速控制量校正值KQISC减少怠速控制量Qa而获得的怠速控制量QISC 。因此，在选择D档的稀燃时，在空转状态下喷射的燃料的路面负荷量与车辆低速行驶期间喷射的燃料的路面负荷量基本上没有差别。因此，根据燃料增加要求实现的基于稀燃的车辆的低速行驶期间的燃料喷射量的增加不会导致发动机的输出转矩过大，从而低速行驶的车辆变得稳定，并且可以保持良好的驾驶性能。

摘要： An upper limit guard is set for a valve overlap amount according to a KCS learning value used to retard-correct an ignition timing in order to suppress knock, and an engine load. As a result, it is possible to make the upper limit guard value a value able to restrict the valve overlap amount to a value equal to, or less than, a value at which an internal EGR amount does not become exvessive during a retard-correction of the ignition timing. By applying the upper limit guard to the valve overlap amount using the upper limit guard value, it is possible to suppress the valve overlap amount from increasing from the optimum value following a retard-correction of the ignition timing, as well as suppress the value of overlap amount from being reduced when it is not deviating from the optimum value and is below the upper limit guard value.

摘要： An engine cooling apparatus includes a flow regulating valve, which adjusts a flow rate of a coolant passing through a radiator provided in a coolant circulation passage of the engine, and an electronic control unit (ECU), which controls an opening of the flow regulating valve such that an engine outlet coolant temperature reaches a necessary target temperature. The ECU sets a basic opening as a feedforward term based on the operation state of the engine. The ECU calculates a final opening from an F/B constant as a feedback term, which is increased or decreased such that the engine outlet coolant temperature reaches the target temperature, and the basic opening. Further, the ECU performs feedback control on the opening of the flow regulating valve based on the final opening. As a result, the responsibility of the coolant temperature control is improved.

摘要： A flow control valve is located in a coolant circuit that extends through an engine. The flow control valve is operated in accordance with a control mode selected from a full closing control mode, a full opening control mode, and a feedback control mode. When switching from one control mode to another, the flow control valve is controlled in accordance with a transitional control procedure selected from different types of transitional control procedures. The transitional control procedure to be performed is selected depending on which control modes are performed before and after the control mode switching and/or the current condition of the engine. Transitional controlling of the flow control valve is thus appropriately conducted.

摘要： An engine output for bringing the drive power of a motor vehicle to a requested value is determined as a target output. One of the lean burn and the stoichiometric burn is selected as a combustion form that achieves a best fuel consumption performance in terms of the control of the actual engine output to the target output. That is, an output value that serves as a criterion for determining whether to switch the combustion force is determined based on the minimum fuel consumption rate during the stoichiometric-burn operation and the minimum fuel consumption rate during the lean-burn operation in which the fuel consumption involved in the rich spike control is taken into account. If the target output is less than the output value, the lean-burn operation is performed. If the target output is greater than the output value, the stoichiometric-burn operation is performed.

摘要： An engine cooling system includes a flow control valve and an electronic control unit (ECU) for controlling the flow control valve. The flow control valve regulates the flow rate of coolant flowing through a radiator in a coolant circuit. The ECU feedback controls the opening size of the flow control valve such that the temperature of coolant at an engine outlet seeks a predetermined target value. During the feedback control, the ECU controls the flow control valve such that the opening size of the flow control valve remains above a predetermined lowest value. As a result, the flow control valve is prevented from falling in a small opening size range in which in which it is difficult to cause the engine outlet coolant temperature to seek the target value, and the engine outlet coolant temperature is favorably adjusted.

摘要： A vehicle drive power control apparatus and method control the speed ratio of a transmission based on a speed shift line that is set so that, within a practical region, the speed shift line is in a low revolution speed side of an optimal fuel consumption line determined based on the efficiency of the engine and the efficiency of the transmission. Therefore, the width of increase in revolution speed from the speed occurring at the beginning of the practical region is curbed. Hence, the fuel consumption resulting from inertia torques caused by fluctuations in engine revolution speed, that is, fluctuations in the revolution speed of the input shaft of the transmission and a fluidic power transfer mechanism, is reduced, so that the efficiency as a whole increases and the fuel economy improves in comparison with the case where the optimal fuel consumption line is used as a control basis.
