Abstract

PURPOSE:To stably generate a secondary voltage enough for firing a spark plug of an engine, by permitting power transistors into a state of electric conduction to flow a current by the output of an L coil. CONSTITUTION:The output of an L coil 12, provided in a magneto 1 and used for charging a battery 10 and lighting a lamp 11, is fed to the base of a power transistor 4 through a resistor 3. The output of sail L coil 12 produces a state of conduction to flow a current in the power transistor 4 that shorts the output of a B coil 2. While at the timing of ignition the output of a P coil 5 permits a transistor 6 into a state of electric conduction to short the output of the L coil 12, and this causes the power transistor 4 to be in a state of cutoff thus a spark plug 8 is ignited.
