1. , the ignition control method in a kind of internal-combustion engine ignition control system comprises the crank reference position detector that detects a plurality of reference angles of a motivation bent axle position in described internal-combustion engine ignition control system;

  • Respond the electric control device of the pulse signal of described crank reference position detector, this device further comprises a CPU and a memory that has processor in advance;

    Described internal-combustion engine ignition control system also comprises the control signal of a described electric control device of response, the ignition mechanism that is used for control ignition time and electric current supply starting time that is made of a power switch element and spark coil;

    Described ignition control method in said system is characterised in that;

    Receive the pulse signal of described crank reference position detector and measure time lag between the described pulse signal, thereby determine the interval speed of rotation in each time lag;

    Calculate according to the above-mentioned interval speed of rotation, determine the mean speed of speed pulsating quantity and crankshaft rotating one circle;

    Mean speed according to the above-mentioned speed pulsating quantity that calculates and crankshaft rotating one circle calculates ignition advance angle and stagnation time or actuation duration, and according to these results, determines firing time and electric current supply starting time.
