Ignition controller

Abstract

Abstract PURPOSE:To prevent from an abnormal engine operation and vibration for an ignition controller provided with a timer circuit generating an output signal in producing an ignition signal not more than a rated time allowing to prevent from an ignition of a spark plug while generating said power signal. CONSTITUTION:An internal combustion engine is operating till a time t1, a collector current of a driving transistor Tr5 repeating intermittently as designated by c. Then, in stopping rapidly an internal combustion engine at a time t1, the output of a timer circuit 8 allows to be in a high level at a time t2 after elasping a time T1, turning on a control Tr7 and turning off Tr5. However, since a condenser 9b is connected between base collectors of Tr7, the collector current thereof is increasing slowly during the timer T2 as shown in d, accordingly the collector current of Tr5 being reduced slowly during the time T2, and preventing from igniting the spark plug 6 at the time t2.
