摘要： A system and method for controlling an engine include determining a desired engine brake torque and modifying the desired engine brake torque based on current engine operating conditions to determine a requested engine brake torque prior to determination of control parameters, including at least one of an airflow and a fuel quantity, to effect the requested engine brake torque. Preferably, the desired engine brake torque is modified by combining the desired engine brake torque with an idle speed torque to generate a first intermediate torque, comparing the first intermediate torque to an actual engine brake torque to generate a second intermediate torque, generating a feedback correction torque based on the second intermediate torque, and combining the first intermediate torque, the feedback correction torque, and a third intermediate torque to determine the requested engine brake torque, where the third intermediate torque represents accessory load or a frictional torque loss which varies with temperature.

摘要： A basic fuel injection amount is calculated based on the intake air amount detected by an air flow meter (19), and the basic fuel injection amount is corrected based on a phase delay of an intake air amount variation between the engine (10) and air flow meter (19) so as to calculate a first correction injection amount. The first correction injection amount is corrected to a second correction injection amount based on an increase amount which is different according to whether or not the engine (10) is in the idle running state. A fuel injector (17) performs fuel injection based on this second correction injection amount. The aforesaid increase amount is determined by multiplying a difference between the first correction injection amount and basic fuel injection amount, by a predetermined gain. Due to this, a shift of the air-fuel ratio to the lean side when a new load such as an air conditioner is exerted on the engine (10) in the idle running state, is suppressed.

摘要： The invention prevents engine speed from being decreased (or engine stall) by a disturbance (such as turning on the air conditioner) during idling. During idle control, a target idle speed is used as an engine speed parameter in place of the actual engine speed to calculate intake air, so that the engine speed is not decreased by a disturbance for very long. Also, target generation torque can be set so as to maintain target idle speed.

摘要： An apparatus for controlling the idle speed of an engine (2) is disclosed. The apparatus includes an electric control unit (ECU) (71) for controlling the engine speed, an air conditioner switch (65) for detecting application and removal of an external engine load, or air conditioner (37), and sensors (36, 66, 77) for detecting that the engine (2) is idling when the vehicle is stationary and when the vehicle is moving. The ECU (71) gradually increases the engine speed by a predetermined amount to shift the engine (2) to a raised idle state when the external engine load (37) is applied and gradually decreases the engine speed by the predetermined amount when the external engine load (37) is removed. The ECU (71) adjusts the engine speed at a certain rate when the vehicle is stationary and at a different rate when the vehicle is traveling.

摘要： When an electric current is supplied to an electrically heated catalyst (5) mounted on a vehicle, oxygen that is required is supplied by setting the air-to-fuel ratio to become lean, and the engine (1) during this period is prevented from losing stability. When the electrically heated catalyst is in a condition to be supplied with an electric current, the alternator (9) driven by the internal combustion engine is disconnected from the battery (8) and the current is supplied to the electrically heated catalyst. At the same time, the air-to-fuel ratio of the internal combustion engine is set to the lean region, and a deviation is found between the present engine running speed and the target running speed found from the operation conditions of the engine. The field current of the alternator is controlled toward a direction in which the deviation decreases and, at the same time, the amount of electric power supplied from the alternator to the electrically heated catalyst is monitored. When an average amount of electric power supplied within a predetermined period of time becomes smaller than a predetermined value, the running speed of the internal combustion engine is forcibly increased to promote the rise of temperature based upon the reaction of the catalyst with the fuel and, at the same time, the internal combustion engine is prevented from losing stability even under the lean conditions.

摘要： When an air conditioner is turned on during homogeneous operation, an equivalence ratio correction factor Δφ is increased sharply and suddenly in such a manner as to show a jump for thereby increasing an engine output torque, and thereafter is decreased gradually with increase of a cylinder intake air quantity, whereby to maintain the engine output toque constant. However, when switching to a homogeneous mode occurs in the middle of the above control, it is not carried out switching to proper torque correction at the time of a homogeneous combustion mode, i.e., torque correction by the use of ignition timing but the torque correction by the equivalence ratio correction factor Δφ continuously. By this, in contrast to the case the torque correction is switched to such one that is carried out by the use of ignition timing correction quantity, a sharp and sudden variation of engine output toque can be prevented. In the meantime, after completion of the torque correction by the above mentioned control, the torque correction at the time of the homogeneous combustion mode is carried out by ignition timing correction. Further, when the combustion mode is switched to stratified combustion during execution of torque correction by ignition timing correction at the time of the homogeneous combustion mode, the torque correction is switched to such one that is carried out by the use of the equivalence ratio correction factor simultaneously with switching of the combustion mode.
摘要翻译：在均匀运转时空调机开启时，等效比校正系数DELTA phi急剧急剧地急剧上升，从而显示出跳跃，从而提高发动机输出转矩，此后随着气缸的增加而逐渐减小进气量，从而维持发动机输出功率的恒定。然而，在上述控制中，当切换到均质模式时，在均匀燃烧模式时不进行适当的扭矩校正，即通过使用点火正时的扭矩校正，但是转矩校正通过等效比率校正因子DELTA phi连续。由此，与通过使用点火正时校正量进行转矩修正的情况相反，可以防止发动机输出转矩的急剧变化。同时，在通过上述控制完成扭矩校正之后，通过点火正时校正来进行均质燃烧模式时的扭矩校正。此外，当在均匀燃烧模式时通过点火正时校正在执行扭矩校正期间将燃烧模式切换到分层燃烧时，转矩校正被切换到通过使用等效比校正因子同时切换燃烧模式。
