摘要： The invention provides torque correction during both homogeneous combustion and stratified combustion. Torque correction is made in response to a torque correction demand (produced when, for example, a gear shift is effected, the air conditioner is turned on, or fuel cut recovery is effected) by correcting the spark timing (or the spark timing and air-fuel ratio) during homogeneous combustion and by correcting the air-fuel ratio during stratified combustion.

摘要： An engine rotation speed during idle running is feedback controlled to a target rotation speed. A basic ignition timing is set based on the rotation speed during idle running, and the ignition timing is feedback corrected based on a difference between a target rotation speed and a measured rotation speed. This feedback correction process and other processes including the setting of the basic ignition timing are separated. A high response ignition timing feedback control is performed by advancing the measuring timing of the rotation speed to a point earlier than the correction timing by at least the processing time required to perform the feedback correction process, and preferably by a value near the processing time. A high response fuel injection amount feedback control may also be performed by a similar process.

摘要： When an air conditioner is turned on during homogeneous operation, an equivalence ratio correction factor &Dgr;&phgr; 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 torque constant. However, when switching to a homogeneous mode occurs in the middle of the above control, switching to proper torque correction is not carried out 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 &Dgr;&phgr; continuously. By this, in contrast to the case in which the torque correction is switched to one that is carried out by the use of ignition timing correction quantity, a sharp and sudden variation of engine output torque 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 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： 当均匀运转时空调开启时，等效比修正系数DELTAphi急剧急剧地增大，从而显示跳跃，从而提高发动机输出转矩，此后随着气缸进气量的增加而逐渐减小 空气量，从而维持发动机输出转矩恒定。 然而，在上述控制的中间发生切换到均匀模式时，在均匀燃烧模式时不进行切换到适当的扭矩校正，即通过使用点火正时进行转矩校正，而是通过使用点火正时的转矩校正 等效比率校正因子DELTAphi不断。 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，转矩校正被切换为通过使用当量比校正因子同时进行的转矩校正 随着燃烧模式的切换。

摘要： When an operation causing a decrease of the engine load is requested, for example, by switching off an air conditioner switch, an idle speed control system calculates a fuel decrease quantity from an engine load decrease quantity, and further calculates an air decrease quantity in accordance with a desired air fuel ratio after the engine load decrease, and the fuel decrease quantity. The control system decreases the air supply quantity to the engine by the air decrease quantity. Then, after the elapse of a preset time interval, the system controls the external load such as the air conditioner so as to reduce the engine load (for example, by turning off the air conditioner), and decrease the fuel injection quantity by the fuel decrease quantity. When the air conditioner is switched on, for example, the control system calculates a fuel increase quantity from the engine load increase, and further calculates an air increase quantity in accordance with the fuel increase quantity and a desired air fuel ratio after the engine load increase. Then, the control system controls the external load to increase the engine load, increases the fuel injection quantity and increases the air supply quantity.

摘要： An intake-air quantity control apparatus for an internal combustion engine with a variable valve timing system associated with at least an intake valve, comprises a control unit controlling an intake-air quantity of air entering the internal combustion engine based on at least one of an intake valve open timing and an intake valve closure timing of the intake valve. The control unit determines a desired internal pressure in an intake-air passage based on a predetermined operating parameter, and detecting an operation delay-time fluctuation rate for at least the intake valve. A desired intake-air quantity is arithmetically calculated on the basis of engine operating conditions. The control unit includes a compensation section which compensates for the desired internal pressure based on at least one of the operation delay-time fluctuation rate and the desired intake-air quantity to produce a compensated internal pressure. A throttle opening is controlled depending on both the compensated internal pressure and the desired intake-air quantity. Also, the intake valve open timing and the intake valve closure timing are controlled depending on both the compensated internal pressure and the desired intake-air quantity.
