| Summary: | The present invention relates to an ignition device for an internal combustion engine having multiple cylinders and direct gasoline injection, at least one ignition coil being provided for each cylinder, the primary side of the ignition coil being switched by an ignition switch controlled by a microprocessor and a spark plug being connected to the secondary side of the ignition coil.
An ignition device for an internal combustion engine having multiple cylinders and direct gasoline injection is described, so that the secondary current conduction time of the ignition coil can be prolonged controllably without increasing the primary current. At least one ignition coil is provided for each cylinder of the internal combustion engine. The primary side of the ignition coil is switched over an ignition switch which is triggered by a microprocessor. A spark plug is connected to the secondary side of the ignition coil. An external voltage can be applied to the ignition coil to prolong the secondary current conduction time, thus supplying the power required for the prolonged secondary current. |
