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： 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 system for internal combustion engines wherein an ignition timing computer circuit starts the computation of an ignition timing in response to the detection of a predetermined angular position of the crankshaft of an internal combustion engine by an angular position detector, and an ignition device ignites the engine according to the computed ignition timing. A pressure detector detects variations of the pressure in the cylinders caused by the ignition of the engine and a retard-advance detector determines whether the angular position of the engine crankshaft corresponding to the maximum cylinder pressure agrees with the desired angular position. This retard-advance detector compensates the computation of ignition timing in the ignition timing computer circuit in accordance with its determination. In this way, the ignition timing of the engine is feedback controlled in such a manner that the pressure in the individual cylinders reaches a maximum value at the desired angular position of the crankshaft.
