An ignition coil system comprises a direct current voltage booster, a coil winding, an electronic switch and a spark plug. The low-voltage end of the direct current voltage booster is used for being connected with a vehicle-mounted power supply. The upper end of the coil winding is connected to the high-voltage end of the direct current voltage booster, and the lower end of the coil winding is connected with the high-voltage center pole of the ignition plug. One current transmitting end of the electronic switch is connected with the lower end of the coil winding; the other current transmitting end of the electronic switch is grounded, and the control end of the electronic switch is used for being connected with an ignition signal. According to the ignition coil system, only one coil winding is needed, and the coil winding is directly acted on the ignition plug so that the electromagnetic coupling loss is reduced; the energy utilization efficiency of ignition is greatly improved, and the cost is lowered. |
