| Abstract: | Based on the structural features of the special IC engine, the demands of its ignition system are first outlined.The internal diagram of the L497 electronic ignition controller and its typical application circuit are introduced.The digital direct ignition system(DDI) is developed by replacing Hall Effect sensors with electronic control unit(ECU) and corresponding external circuit.Ignition voltages of the DDI secondary coil varying with the charge time and the supply voltage are measured.The experimental results indicate that the DDI system is reliable and feasible for the studied IC engine prototype. |
