摘要： A spark plug includes a body of dielectric substance mounted on one of central and earth electrodes and having polarization effects. A gap for capacitive discharge is defined between the body of dielectric substance and the other of the electrodes, and a gap for inductive discharge is defined between the electrodes, which gap for inductive discharge is larger in dimension than the gap for capacitive discharge. With the arrangement, capacitive discharge to be produced in the early stage of discharge is caused at low discharge breakdown voltage due to polarization effects of the body of dielectric substance, and inductive discharge taking the main part of discharge for ignition is produced by utilizing the capacitive discharge of low voltage as trigger, thereby lowering discharge breakdown voltage to improve ignition performance of the spark plug.

摘要： Method and apparatus is provided for calculating an optimum ignition timing for an internal combustion engine on the basis of values set in dependence on operating conditions of the engine. With a view to prevent ignition times in two successive cycles from differing remarkably from each other, the ignition time or angle for the current cycle is controlled with reference to the ignition time or angle in the just preceding cycle. As one example of the control, in the case where the ignition time electronically anticipated for the current cycle appears to have deviated from the preceding ignition time by more than a predetermined value, the anticipated ignition time is modified to result in the optimum ignition time by adding to or subtracting from the anticipated ignition time a predetermined value. Alternatively, the optimum ignition time may be given by a mean value of the anticipated ignition time and a plurality of the preceding ignition times.

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.
