Abstract
An ignition system for an internal combustion engine is designed so that it can be inexpensively produced in a manner advantageous from a standpoint of production engineering. The ignition system includes a shaft in a cylinder head of an internal combustion engine and a coil rod, which can be inserted over a portion of its longitudinal extension into the shaft. The coil rod forms an open magnetic circuit which is controlled by a tubular, longitudinally slit return plate. This return plate is set apart from the coil rod, in the shaft of the cylinder head. The ignition system is intended to be used in the automobile industry.
