FIELD: mechanical engineering; internal combustion engines; electronic ignition devices. SUBSTANCE: high frequency generator supplies high frequency generator supplies high frequency square waveform alternating current to spark plug electrodes at two modes with different voltage amplitudes. Amplitudes of alternating current of first mode is not sufficient to make spark jump, while amplitude of second mode is sufficient for sparking. EFFECT: improved reliability of ignition system. 1 cl, 2 dwg |
