ABSTRACT:
An energy-on-demand vehicular ignition system with a programmable re-striking and minimum single-strike energy output whereby at idle engine speed and lowest load, each coil will be re-struck or discharged the maximum number of times permitted by the coil design within a limited time interval representing the beginning of the combustion event and occurring within 0-2% MFB of the ignitable air fuel mixture within the combustion chamber. The system strategy also includes programmable re-striking whereby the system will default to a single-strike at conditions above a predetermined range of operating conditions, in particular, at a particular engine speed condition and a particular engine partial load condition. In between the conditions at (i) idle engine speed and lowest load on the one hand and, (ii) a predetermined engine speed and partial load condition. The ignition strategy includes the coil being re-struck more than once, with the particular number of re-strikes being determined in accordance with a preset schedule as predetermined to be ideal for complete combustion at the operating conditions being sensed.
