This paper presents a solution to improve performance of AC capacitor discharge-ignition (AC-CDI) systems for most of motorcycles presently used in Vietnam. Due to low cost, these AC-CDI systems normally use very simple structures and electrical electronic-components, especially their electronic control units (ECUs). Their main disadvantages are high power loss and only one or several different constant ignition timings. With a low cost micro-processor and good control algorithms, a new design for AC-CDI ECU could reach both higher power efficiency for the system and highly variable ignition timing related to engine rpm. These advantages could lead to more powerful spark, better power, higher fuel economy, lower exhaust emissions and smoother driveability for engine.
