Ignition module and a spark plug

The ignition module is single-channel and generates low-frequency pulse voltage to the spark plug. The main characteristics are:

• Nominal voltage: 28 V

• Nominal current consumption: < 1.5 A

• Input voltage range: 14 V to 30 V

• Output voltage: 2.5 kV to 3 kV

• Output energy: > 0.6 J

• Discharge frequency at 14 V: 3 Hz to 6 Hz

• Discharge frequency at 30 V: 4 Hz to 7 Hz

The type of spark plug is not strictly specified. A preliminary review of existing options indicates high efficiency when using shunted surface-discharge spark plugs (surface-gap spark plugs / erosion-type plugs). Therefore, we'd like to obtain initial information on:

• Feasibility of manufacturing a surface-discharge spark plug with operating conditions that match the parameters of the ignition module given above;

• Feasibility of using alternative spark plug options (simplified or off-the-shelf standard).
