Research on the New Ignition Control System of Lean- and Fast-Burn SI Engines

In order to make SI engines have a stable and reliable running under lean-burn condition, the authors had put forward and made researches on a new ignition control system, namely superposed-energy ignition system. Then, the authors had mainly studied the charge and discharge control time of the system that was controlled based on the 51 series single-chip microcomputer. Moreover, the control circuit and program had been developed. Finally, the control program was debugged and compiled by Keil technical platform. The results showed that the feasibility of the control time of charge and discharge using the 51 series SCM was validated.
