PURPOSE:To obtain optical ignition timing by detecting the knock signal from the output of vibration acceleration sensor for engine without subject to disturbance of various noise component and controlling the ignition timing in accordance with said knock signal. CONSTITUTION:Referential ignition signal from referential ignition signal generator 8 is provided through a wave shaper 10 and a phase shifter 8 to a switching circuit 11 to produce a ignition signal in a ignition coil 12. Upon occurrence of knocking the output from an acceleration sensor 1 includes a knocking signal. In the signal passed through a frequency filter 2 and an analog gate 3, a knocking signal is lapped over an ignition noise of mechanical and electrical noises. A pulse is produced at the output of a comparator 6 and the output from an integrator 7 shifts the output from the wave shaper 10 to be applied on a phase shifter 7 to the lagging side. Consequently the ignition timing is lagged to suppress the occurrence of knocking. |
