<p>An ignition device for an internal combustion engine having transistor means (301) for on-off controlling a primary current of an ignition coil (2) to produce a high voltage for spark ignition, comprises a reference voltage generator (301) for producing a temperature compensated reference voltage, a primary current detecting circuit (302) for producing a voltage corresponding to a primary current of the ignition coil (2), a comparator (314,315,316) for comparing said temperature compensated reference voltage with said voltage produced by said primary current detecting circuit (302) and a control circuit (308) responsive to an output of said comparator (314,315,316) to control a base voltage of said transistor means (301) to a predetermined constant value.</p> |
