Abstract: This paper designs a two-stroke engine digital ignition system(DCI) using MC68HC908 microcontrollers.The DCI system solves the problem that the capacitive discharge ignition(CDI) breaks off fire at low speed and backflash at high speed,which has lower fuel consumption and exhaust emission compared with the CDI system.

Keywords: Digital Ignition System(DCI);Ignition Advance Angle;MC68HC908JK3
