Abstract
An ignition system supplies high-voltage to spark plugs via field emitters. An ignition control device produces the ignition cycle for the ignition system and controls the ignition process of the ignition system. The field emitters couple the ignition control device to the spark plugs. The field emitters switch and regulate the high-voltage for the spark plugs.
Claims12
An ignition system comprising:
- a spark plug;
- a high-voltage source coupled to the spark plug and for generating and maintaining an ignition spark in the spark plug;
- an ignition control device coupled to the spark plug and the high-voltage source, for producing an ignition cycle in the ignition system, and for controlling an ignition process of the ignition system;
- a field emitter for coupling the spark plug to the high-voltage source and the ignition control device;
- an operating voltage source;
- and
- a second field emitter for coupling the operating voltage source to the field emitter.
