摘要： The ignition timing of an internal combustion engine is controlled to an optimum by compensating for engine knock. A microcomputer includes a memory for storing steady-state and transient-state ignition timing variables which are derived as a function of an operating condition of the engine. If engine knock occurs during a steady running state, the stored steady-state ignition timing variable is trimmed and if engine knock occurs during a transient state, the stored transient-state ignition timing variable is trimmed. Ignition is caused to occur in response to the stored value of the trimmed steady-state or transient-state ignition variable according to the detected engine condition.

The ignition timing of the engine is retarded in response to the detection of knocking in the engine and the amount of retard is increased as compared with the amount of retard provided under the steady-state condition when the knocking occurs during the acceleration operation of the engine and the frequency of occurrence of knocking is high.

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 knocking vibration detecting unit (1) and a knock deciding unit (c) are integrated, and the communications of a knock intensity between the knock deciding unit (c) and an engine controlling microcomputer (7) are carried out in combination of a change from the previous value of a signal line level. In the engine controlling microcomputer (7), the ignition timing is controlled by a predetermined retard angle in case of combination of no change of the present read signal line level from the previous signal line level.Thus, an internal combustion engine is prevented from any damage by relieving a failure without fail when a signal line (10) is troubled, while minimizing the influences of noises and reducing the space and size of an ECU.

摘要： In a knocking discriminating system for an internal combustion engine, a knocking detecting signal obtained from a knocking sensor is passed through a band-pass filter for obtaining a sinusoidal waveform of approximately 8 KHz. The sinusoidal waveform signal is then applied to an A/D converter, the operational timing of which is controlled by a microcomputer, so that only a part of the knocking detecting signal nearby the peak portion is converted into digital values. A discrimination level is prepared from the average value of the digital values, and the knocking status is discriminated by comparing the maximum value of the digital values thus converted with the discriminating level.

摘要： An ignition timing control arrangement for an internal combustion engine having a plurality of cylinders. It is determined whether the same cylinder is knocking on successive engine cycles or whether different cylinders are knocking. The ignition timing of only a single cylinder is retarded to cause a non-knocking ignition if the same cylinder is knocking on successive engine cycles. However, ignition timing of all cylinders is retarded to minimize the knocking and maximize the engine torque if different cylinders are knocking.

摘要： There is disclosed a fuel property detector for detecting a property of fuel injected by a fuel injector into a cylinder of an internal combustion engine. The fuel property detector includes an injection commander, a change detector, and a fuel property determiner. The injection commander commands the fuel injector to perform a fuel injection for fuel property detection into the cylinder of the engine. The change detector detects a change in the rotational speed of the engine which is caused by the fuel injection for fuel property detection. The fuel property determiner determines the property of the fuel based on the change in the rotational speed of the engine detected by the change detector.

摘要： In a system, an actuator is linked to a valve rotatably installed in a passage through which gas flows. The actuator changes torque to be applied to the valve so as to adjust a rotational position of the valve based on a deviation between a current position and a target position. In the system, a first storing unit stores therein a first threshold. The first threshold is defined in a variation range within which a torque parameter is variable depending on change in the torque to be applied to the valve. The first threshold allows whether there is a possibility that an operation of the actuator is unstable. If the torque parameter substantially shifts either to or through the first threshold in the variation range, a restricting unit restricts variation in the torque parameter with the gas-flow being substantially kept through the passage.
