摘要： In the method of feedback controlling the air-fuel ratio of an internal combustion engine, the feedback control is stopped for a predetermined period of time at a specified time or condition of the engine, and the air-fuel ratio is controlled in accordance with a control signal having a value corresponding to the average value of the integrated compensation signals. In addition, a factor affecting the center value of the controlled air-fuel ratio is adjusted in accordance with the output signal of a comparator circuit generated during the time that the feedback control is being stopped.

摘要： An apparatus for controlling an ignition timing of an internal combustion engine for each ignition cycle. The apparatus fetches digital signals representing an intake pipe negative pressure and the number of revolutions of the internal combustion engine, and a digital signal representing a fuel injection time, and computes a basic timing of ignition spark by using the intake pipe negative pressure and the number of revolutions. When the intake pipe negative pressure and the number of revolutions, both being sensed currently, have ratios of changes falling within given values, compared with those sensed precedingly, correction values read out from a memory device on the basis of the intake pipe negative pressure and the number of revolutions are corrected so as to reduce the fuel injection time in accordance with the result of a comparison of the fuel injection time of the fuel injection currently performed with that of the fuel injection precedingly performed. An ignition timing is determined by correcting the basic ignition timing depending on the corrected correction value of the ignition timing. The corrected correction value is loaded into the memory device in place of the correction value before correction. When the intake pipe negative pressure and the number of revolutions, both being sensed currently, changes with ratio which falls out of fixed values, compared with those sensed precedingly, the basic ignition timing is corrected by the correction value of ignition timing read out on the basis of the intake pipe negative pressure and the number of revolutions, without correcting by the fuel injection time, thereby to determine an ignition timing. An ignition signal is applied to an internal combustion engine igniting device in accordance with the ignition timing determined.

摘要： An O2 amount in the intake air is determined based on a fresh air and an EGR gas. A consumed O2 amount is determined with a command injection amount Qr. Then, the consumed O2 amount is subtracted from the O2 amount in the intake air to obtain an exhaust O2 amount. An exhaust O2 concentration is estimated based on the exhaust O2 amount. According to the invention, the system is not affected by a delay for the exhaust gas to reach an O2 sensor and a delay of the chemical reaction in the O2 sensor. Therefore, the exhaust O2 concentration can be highly precisely estimated compare to the case in which the exhaust O2 concentration is detected by the O2 sensor.

摘要： In a fuel infection valve, a valve chamber of a three ways valve is selectively communicated to drain and high pressure conduits and also communicated, via a main orifice, to a control chamber for controlling valve opening and closing operations of a nozzle needle. The control chamber may be communicated via the main orifice and the valve chamber to the drain conduit or the high pressure conduit, when a valve body is driven by a piezo actuator to open or close the drain conduit and close or open the high pressure conduit. The control chamber is always communicated via a sub orifice to the high pressure conduit without bypassing the three ways valve. Accordingly, hydraulic pressure in the control chamber is slowly decreased at a valve opening time and is rapidly increased at a valve closing time so that a lift characteristic of the nozzle needle is improved.

摘要： An air-fuel ratio control apparatus for an internal combustion engine which is equipped with an air-fuel ratio sensor for sensing an actual air-fuel ratio of a mixture to be introduced into the engine and a target air-fuel ratio setting section for setting a target air-fuel ratio of the engine. Also included is a controlled-amount calculating section for setting an optimal feedback gain on the basis of a predetermined dynamic model of the engine to calculate a controlled amount in accordance with the predetermined optimal feedback gain so that the actual air-fuel ratio becomes equal to the target air-fuel ratio. A fuel supply amount to the engine is determined on the basis of the calculated controlled amount, and the control responsiveness of the controlled-amount calculating section is suppressed when the engine is in a speed-decreasing state. This arrangement can adequately control the air-fuel ratio of the engine irrespective of the engine speed-decreasing state.
