INTERNAL COMBUSTION ENGINE CONTROL SYSTEM

摘要

According to one embodiment, an internal combustion engine ignition system, including: a plurality of spark coils each having a primary coil and a secondary coil, each secondary coil being coupled to a common spark plug to apply a high voltage thereto; a plurality of primary current generation module provided correspondingly with the spark coils and configured to asynchronously generate primary currents respectively flowing through the primary coils; one or a plurality of primary current detection module configured to detect each of the primary currents; and a primary current control module configured to adjust an output power supplied to each primary coil in accordance with a change in the primary current to thereby control an increase rate of the primary current.
