  "textContent": "The invention simplifies the structure of a magneto generator and stabilizes the operation of an internal combustion engine at the time of start-up, thereby providing an ignition device simplified in structure and reduced in size and providing improved safety to the internal combustion engine. In an ignition device for a capacitive discharge internal combustion engine, an ignition timing signal is calculated with a cycle detection signal obtained at a timing at which a forward voltage portion of an output voltage from a generator coil has reached a cycle detection voltage for making continual ignition operations available, and a peak voltage detection signal and a start-up voltage detection signal are obtained in accordance with a delayed reverse voltage portion of the output voltage from the generator coil. In a preset normal region speed or less in which a load is coupled to the engine, an ignition signal is output immediately after the peak voltage detection signal hasbeengenerated. In a normal region speed or more , anignition signal is output after the duration of the ignition timing signal from the point in time of output of the cycle detection signal. At the time of start-up, an ignition signal is output in response to the start-up voltage detection signal according to the cycle detection signal. This eliminates the need of a coil for generating a timing signal and provides a safe start-up operation.",
