Study on ignition timing feedback control using the knock sensor

노크센서를 이용한 점화시기 피이드백 제어에 관한 연구

The ignition timing feedback control system was studied to enhance the engine power and to reduce the fuel consumption by optimizing the spark timing. The signal of a piezo-electric vibration transducer attached to the engine block was compared with that of a pressure transducer in order to determine the knock intensity. With the result of comparison the ignition timing feedback control system which detect the knock and correct the spark timing was set up. The ignition could be more advaced with this control system than the existing system without the continuous knocking, therefore the engine torque was increased.
