Claims

[Scope of utility model registration request]

A pulser, an ignition coil, and a spark plug, upon receiving a signal from the pulser, control the energization and interruption of the primary side current of the ignition coil to send an electric spark to the spark plug connected to the secondary coil. In an electronic advance ignition system for an internal combustion engine consisting of a control circuit that controls the position, an idle switch is provided on the internal combustion engine side to detect whether the throttle position of the internal combustion engine is in an idle state or in a running state, An electronic advance ignition system characterized in that the operating level of a spark position control circuit is changed depending on the state of an idle switch, and the ignition position is delayed in an idling state compared to a running state.
