PURPOSE:To secure an ignition point characteristic in high speed lag angles excellent in ignition point accuracy, by having a pulser made up in detecting only a reference point in order to hardly receive any effect from outside conditions and simultaneously designing the ignition point to be always controlled by means of electronic circuits. CONSTITUTION:In an electronic lead angle non-contact ignition system with an ignition point detecting pulser 3, an ignition point control electronic circuit and an ignition circuit 8, a pulser output is inputted into an FF circuit 9 via a delay circuit 6 after being rectified and, thanks to the output of this FF circuit 9, the ignition point is to be determined in design. Then, the pulser 3 is made to detect only a reference point in order to calculate the ignition point, from a reluctor 1 which is synchronously rotated with an engine, thereby making any effect from outside conditions unreceivable. |
