Claims

[Scope of utility model registration request]

First and second non-contact ignition circuits are provided for supplying high voltage for ignition to first and second spark plugs installed in one cylinder of the internal combustion engine, respectively, and the first and second
An ignition system for an internal combustion engine that triggers a non-contact ignition circuit using a common ignition timing signal includes a flip-flop circuit that inverts each time the ignition timing signal is generated; comprising first and second semiconductor switches that operate, the operation of the first semiconductor switch inhibiting the ignition operation of the first ignition circuit, and the operation of the second semiconductor switch inhibiting the ignition operation of the second ignition circuit; an alternate ignition control circuit that prevents ignition operation; and an alternate ignition control circuit that detects the temperature of the internal combustion engine and prevents the operation of the first and second semiconductor switches when the temperature is below a set value. An ignition device for an internal combustion engine, comprising a simultaneous ignition control circuit that allows the operation of the ignition circuit.
