PURPOSE:To prevent a false motion caused by a noise without processing a signal by means of a C-R circuit, by shutting off a signal course ranging from a pick up coil to an ignition coil in the case of a spark discharge from an ignition plig. CONSTITUTION:An ignition coil 210 generates a high voltage in synchronization with the rotation. An ignition position correcting circuit is theoretically composed of a proper voltage value of a voltage generated at a pick up coil B and an intermediate output of an amplifying circuit I, and reduces an ignition delay. A noise killer circuit K cuts off forcibly a signal course ranging from the pick up coil B to an ignition coil 210 for the duration of a proper period after a primary current is interrupted, and thus, an output will be prevented from being influenced by a spark noise. |
