The high-speed performance of the conventional multi-cylinder coil ignition system is limited by the reduced contact dwell times with increasing speed, and by the mechanical limitations of cam operated contact breakers.The introduction of semiconductor devices, and their continued development, has enabled a racing eight-cylinder contactless ignition system to be produced, capable of providing ignition for engine speeds up to 15,000 rpm. This system is described, along with a transistor assisted contacts system and a contactless system for conventional vehicles.
