    摘要： A knock control system for an internal combustion engine has a knock discrimination level. If an output signal from a knock sensor is higher than the knock discrimination level, then the knock control system determines that the engine is subjected to knock and retards the ignition timing. If the knock sensor output signal is lower than the knock discrimination level, i.e., if no knock or detonation is detected over a prescribed period of time, then the ignition timing is advanced. The knock discrimination level is corrected such that a probability that the maximum value of the knock sensor output signal will exceed the knock discrimination level is greater in a knock control range than outside of a knock control range.

    摘要： In a system for retarding an ignition timing of the engine depending on a signal from a knock detector, the knocking intensity and the knocking frequency are discriminated in accordance with the signal of the knock detector. On the basis of the discriminated results, the system provides a small amount of retard angle for ignition timing per one knocking when the knocking frequency is low, that is, the interval between knocking signals is long and the intensity of knocking is light. On the contrary, the system provides a large amount of retard angle when the interval is short and the intensity is heavy.

    摘要： A spark timing control apparatus controls the spark timing to retard or advance in accordance with the output signal from a knock sensor. An accelerating condition of the engine is determined depending on a particular knock occurence patterns including; whether the interval of knock occurences is larger or small, the total amount of retard angles is larger or small, or the frequency of knock occurences. When the accelerating condition is determined, the advancing rate of the spark timing is increased until a steady state of the engine operation is determined based on the output signal of the knock sensor.

    摘要： A fourth cylinder is mounted with a cylinder pressure sensor. The injection timing of the fourth cylinder is operated so as to feedback control the ignition timing of the fourth cylinder, which is detected by the cylinder pressure sensor, to a target ignition timing. The ignition timings of the first cylinder to the third cylinder are indirectly controlled by operating the injection timings so as to make output torques produced by combustion in the first cylinder to the third cylinder correspond to an output torque produced by combustion in the fourth cylinder.

    摘要： A compression ignition internal combustion engine includes injectors, each of which injects fuel into a corresponding cylinder. An ECU determines target ignition timing based on engine operational information and adjusts fuel injection start timing and a fuel injection quantity of each injector based on the target ignition timing. The engine further includes an air/fuel ratio sensor, which senses an oxygen concentration of exhaust gas. The ECU corrects the target ignition timing based on the oxygen concentration, which is sensed with the air/fuel ratio sensor, with reference to a predefined relationship between the oxygen concentration and ignition timing for achieving a generally equal constant torque of the engine.

    摘要： A gas concentration detector prevents deviation in output due to a difference in oxygen reactivity between electrode materials to accurately detect a specific gas component in a gas to be measured, such as NOx in an exhaust gas. A sensor element in an NOx sensor has a pump cell in a first chamber and a sensor cell for decomposing NOx and any remaining oxygen and a monitor cell for decomposing only remaining oxygen in a second chamber. An NOx concentration is detected based on a difference in current output between the sensor cell and the monitor cell. Since the sensor cell and the monitor cell have different oxygen reactivities, an output of the monitor cell is smoothed through a band-pass filter or the like so that output responses of the sensor cell and the monitor cell are made to substantially match each other, thereby eliminating any deviation in output.

    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.
