Title: Ignition timing controlling system for internal combustion engine
Inventor: IWATA TOSHIO
IPC: F02P5/153
Filed: 1979-05-14
Abstract: PURPOSE: To obtain optimal ignition timing of an internal combustion engine, by detecting a knock signal from the output of a sensor for detecting vibration and acceleration of engine, in the manner not disturbed by various noise components involved in the output, and controlling the ignition timing of engine in response to the knock signal.  
     CONSTITUTION: Rotation signal, produced by rotation signal generator 9 along with rotation of engine in the manner corresponding to particular characteristics of ignition timing, is shaped in wave-form shaping circuit 10 into on-off pulses having a required time duration, and switching circuit 11 is driven via phase shifter 8, thereby interrupting current supply to ignition coil 12. Here, engine vibration is detected by acceleration sensor 1. When knocking is caused, knock signal is superposed on mechanical noises since output of sensor 1 is passed through frequency filter 2 and analogue gate 3. The output of sensor 1 is then furnished via comparator 6 to integrator 7, and by the integration voltage, phase of the signal in circuit 10 is delayed by phase shifter 8, thus preventing knocking of engine.
