Ignition system for an internal combustion engine

Patent ·
OSTI ID:6045143

This patent describes an ignition system for an internal combustion engine. It consists of spark plugs, a low dc voltage supply, an ignition coil, a distributor, two dc-dc converters, and a capacitor. The ignition coil has a primary and secondary winding. The current flow of low dc voltage supply through the primary winding is interrupted in order to generate a high voltage surge at the secondary winding whenever the engine rotates through a predetermined angle. The distributor connects the secondary winding of the ignition coil to the spark plugs. The dc-dc converters provide first and second highly boosted dc voltages. The first dc voltage from the converters passes through the secondary winding in order to continue the supply of energy to one of the spark plugs by way of the distributor. The second dc voltage is discharged by the distributor to the capacitor through one of the spark plugs.
