    摘要： An ignition timing control system for an internal combustion engine in which an angular position of the internal combustion engine is detected, and on the basis of the signal thus obtained by detection, the ignition timing of the internal combustion engine is determined by calculation in a computing device. A knocking condition is judged by a detection signal produced from a knocking detector of the internal combustion engine, and the ignition timing is corrected by the judgement of knocking. In view of the fact that the knocking occurs only during a certain period of the driving cycle of the internal combustion engine, a knocking condition is judged by comparing a detection signal produced from the knocking detector during the time in the absence of knocking with a detection signal produced during the time in the presence of knocking.

    摘要： It is discriminated in an ignition timing control system for an internal combustion engine whether the ignition timing arithmetically calculated on the basis of sensed operating conditions of the engine lies within a predetermined range of ignition timing. When the result of discrimination indicates that the calculated ignition timing lies within the predetermined range, ignition occurs at that instant, while when the result of discrimination indicates that the calculated ignition timing does not lie within the predetermined range, the result of calculation is disregarded, and ignition occurs at a predetermined instant.

    摘要： An ignition timing control system is provided with an ignition timing computing unit which determines a maximum acceleration ignition advance .alpha. ACMAX in accordance with an intake pressure difference P and a water temperature T of the engine. When an acceleration is detected by a rapid movement of an acceleration pedal, the maximum acceleration ignition advance is added to the normal ignition advance. Thereafter, the maximum acceleration ignition advance is gradually reduced to zero in accordance with the lapse of time or a change in the engine speed.

    摘要： An ignition system for an internal combustion engine comprises knock detecting means for detecting knocking of the engine, and ignition timing control means for controlling the ignition timing of the engine in response to the presence or absence of the knocking condition. The knock detecting means detects the pressure in the cylinders of the engine to detect the occurrence of knocking by the fact that the detected pressure includes a high frequency pressure variation. The ignition timing control means is responsive to the output of the knock detecting means, whereby as long as no knocking is detected the ignition timing is controlled to provide the minimum advance for best torque (MBT) and ensure improved engine power efficiency and fuel consumption, whereas when knocking is detected the ignition timing is retarded in relation to the minimum advance for maximum torque (MBT) to prevent the engine from knocking.

    摘要： Method and system for controlling ignition timing includes the steps of and means for discriminating when the time interval between knocking indicative signal pulses is shorter than a particular time period, and controlling ignition timing at a rate related to the frequency of occurrence of knocking to prevent the knocking from occurring. A pulse train is generated having an interval shorter than that of the knocking signal pulse train when the interval of the knocking signal pulse is shorter than the particular time period. The generated pulse train is fed to a control circuit for determining the time by which ignition pulses should be delayed.
