Abstract
A new high-energy, electronic ignition (HEI) system with substantially improved performance and durability has been developed for automotive gasoline engines. All components of the system are integrated within the distributor, and no scheduled parts replacement or adjustment of system components is required. The requirements of system performance and durability, which guided the development of the new system, are outlined. New concepts, materials, and technology used in the design and development are illustrated and explained. A discussion of the operation and limitations of both breaker-operated and transistor systems explains the need for dwell time control and coil primary current regulation. These are new control functions incorporated in the HEI system which result in reduced component size and power dissipation which is essential for the integral design.
