    摘要： A system for controlling ignition timings in an engine wherein ignition signals in the specific cylinders are previously advanced by a predetermined value over ignition signals in other cylinders, the knockings in the specific cylinders are detected, and ignition timings in all the cylinders are delayed in accordance with said knockings, whereby strong knockings which would otherwise be caused to all the cylinders are prevented in advance, the ignition timing control of knockings in the engine can be effected irrespective of the accuracies of a knocking sensor.

    摘要： A device for controlling the vacuum advancing of ignition timing including a vacuum advancer, a diaphragm valve, a first vacuum port opened to an intake passage which is positioned so as to be immediately upstream of a throttle valve when it is fully closed and downstream of the throttle valve when it is slightly opened. A second vacuum port is located absolutely downstream of the throttle valve, wherein the diaphragm valve produces a fraction of the intake manifold vacuum when the throttle valve is fully closed while it communicates therethrough the intake manifold vacuum supplied from the second vacuum port when the throttle valve is opened so as to position the first vacuum port at the downstream thereof.

    摘要： A spark timing control device for use in an internal combustion engine, which includes a pressure control valve wherein when an input vacuum is not higher than a given vacuum level, an output vaccum remains at a zero level, and when the input vacuum is not lower than the given level, the output vacuum will be a product of a proportional constant and the difference between the input vacuum and the aforesaid given vacuum level; a pressure source; and a vacuum advance control mechanism. The pressure source is connected to the input side of the pressure control valve, while the output side of the pressure control valve is connected to the vacuum advance control mechanism.Various modifications of the pressure control valve employable in the spark timing control device are also presented.

    摘要： An ignition timing control system in a spark ignition type internal combustion engine which has multiple cylinders, wherein ignition pulses generated in accordance with the operating condition of the engine are delayed in response to knockings detected to control the ignition timings to the optimum advance conditions free from knockings, has such characteristic features that respective cylinders of the engine are controlled in ignition timing independently of one another, a detected knocking signal is divided for the respective cylinders and only the ignition pulses corresponding to the cylinders of knocking is delayed so that the optimum advance conditions for the respective cylinders can be obtained.
