2. Description of the Related Art An internal combustion engine ignition device according to the conventional basic technology instantaneously generates a high voltage in a secondary coil of an ignition coil by an interrupter by a mechanical switch action, and applies the high voltage to a spark plug. This is a device that generates a capacity discharge to facilitate ignition. The spontaneous spark generation that occurs in this manner is a well-known technique of a contact ignition type electric circuit for igniting a fuel-fuel mixture. In recent years, the number of devices used in combination, such as a transistor ignition device, has increased.

[0003] Although there is a specific example of an electric ignition device for an internal combustion engine, the circuit configuration as in the present invention has not been found. Also, for reference, the spark plug ignition operation will be described as an example.
The spark plug is caused to discharge at a predetermined timing after the start of the fuel injection. However, as an example, the fuel injection timing is about 10 degrees before the start of compression at the start and 5 degrees before the compression top dead center at the time of idling. It is common that the spark plug discharge operation is ignited in a single shot.

[0004] A mechanical switching action and a switching action of a transistor are mainly used. This intermittent action instantaneously generates a high voltage due to the electromagnetic induction action of the primary and secondary coils of the ignition coil. The current in the primary coil is cut off sporadically, and a current is induced in the secondary coil, so that a spark discharge occurs in the spark plug. However, when the rotation speed is high, a limit point of the rotation speed with respect to the discharge of the electric spark occurs. This is because the current flowing through the primary coil decreases, and it becomes difficult to perform an operation of inducing a high voltage in the secondary coil. It is a characteristic of the coil,
This is because its own impedance has a great influence. In addition, the floating capacitance C and the reactance L existing in the coil are also involved, and the function of the resonance circuit is also involved, so that a current component higher than the resonance frequency hardly flows. As a result, a high voltage is not generated as the induced voltage decreases in the ignition coil.

Even if the spark plug is ignited before or near the compression top dead center, there has been a limit to the spark discharge at high speed rotation in the past. There was a need for an ignition method that would not cause this ignition to misfire. Therefore, the ignition coil, which is a feature of the present invention, has an improvement factor. However, the structure of the conventional ignition coil is impossible and requires another improvement measure. In particular, there was no problem during low-speed rotation, but in the high-speed rotation range, the impedance of the coil greatly affected the generation of electric spark,
It was difficult to generate stable electric energy. This is because the impedance peculiar to the ignition coil became an obstacle. That is, it is because the concept of time, which is the action of electromagnetic induction, is related to the (2πfL) frequency (rotational speed) of electric energy. Therefore, the problem can be solved by designing the ignition coil in consideration of the influence of the frequency.

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides an ignition device for an internal combustion engine and a spark plug arranged on a cylinder, which divides the ignition of the ignition plug into a plurality of ignition coils. If the time period in which the current flows alternately to reduce the time period in which each current flows is shortened,
The effect is reduced in the same relation as the coil impedance is reduced in relation to the f frequency of L). In addition, an HD diode (a slight change even if it is removed) is provided as a current check valve on the secondary side of the coil between the ignition coil and the spark plug, and a high voltage is alternately supplied to the spark plug.
