IGNITION CONTROL DEVICE OR IGNITION CONTROL METHOD FOR INTERNAL COMBUSTION ENGINE

摘要

PROBLEM TO BE SOLVED: To provide an ignition control device or an ignition control method, which can supply optimal discharge energy in accordance with the operation situation of an internal combustion engine. SOLUTION: The ignition control device includes an ignition plug which ignites a fuel-air mixture for every cylinder and an ignition coil used for supplying electric energy to the ignition plug. The ignition coil is provided with at least two or more primary coils and one or more secondary coil, or two or more ignition coils are provided in parallel. The ignition control device is also provided with a means of predicting required secondary voltage from the internal combustion engine. The discharge energy which is supplied to the ignition plug is increased or decreased by controlling an ignition signal simultaneously or individually based on the required secondary voltage.
