    摘要: An ignition apparatus for an engine limits the primary winding current of an ignition coil to a prescribed level. The conducting time of drive transistors which control the primary winding current is controlled on the basis of the voltage across a capacitor which is charged by a signal generator. At normal engine speeds, when the primary winding current reaches the prescribed level, current is bypassed around the capacitor by a bypass transistor. When the engine is cranking and the signal generator voltage is low, a switching transistor disables the bypass transistor, and the capacitor is not bypassed, thereby preventing misfiring.

    摘要: An ignition device for an internal combustion engine includes a transistor circuit used to turn a primary current of an ignition coil on and off to produce a high voltage for spark ignition. A reference voltage generator produces a temperature compensated reference voltage. A primary current detecting circuit produces a voltage corresponding to a primary current of the ignition coil. A comparator compares the temperature compensated reference voltage with the voltage produced by the primary current detecting circuit. A control circuit responsive to an output of the comparator controls a base voltage of the transistor circuit to a predetermined constant value.

    摘要: An ignition coil for an internal combustion engine with a compact height and width includes an actuated magnetic portion of an iron core around which a primary coil is wound having an axis line crossing an ignition plug axis line of the internal combustion engine at a right angle; and a switching unit which is disposed at an end of the actuated magnetic portion vertically to the axis line of the actuated magnetic portion and intercepts a primary current flowing through the primary coil. This ignition coil can be manufactured at a greatly reduced cost, compared to the conventional ignition coil in which only one of the height or width is made compact, by reducing the required size of the press mold for the case and by reducing the initial investment for the equipment.
