    摘要: In an ignition system for an internal combustion engine, a digital system for computing the timing advance is provided. Constants approximating the curve of timing advance v. engine speed are stored in a microprocessor. The positive half waves of primary current in the magneto generate the ignition energy and also generate a reference signal for controlling the actual ignition time. The sequence of reference signals is also used to generate a digital value indicative of engine speed. The latter is used to address the read only memory in which the constants for approximating the timing advance curve are stored. After each reference signal, the value read out from the read only memory is counted down by a counter. When the counter reaches the value of zero, ignition is started.

    摘要: An additional diode is provided in series with the charging diode through which the storage capacitor of a magneto ignition system is charged and the shutdown switch for the engine is connected between the common connection of the two diodes and the common connection of the magneto generator, and the capacitor diodes, because of their high back resistance, prevent any high positive or negative voltages from appearing across an open shutdown switch.
