Ignition Systems for Gasoline Engines Bosch Technical Instruction

At the dawn of the automotive age, designing a suitable ignition system for the spark-ignition engine represented ? as formulated by automotive pioneer Carl Benz ? ?the crux of all our problems. ?Among the exceptional talents focused on resolving the thorny issues of the day was that of Robert Bosch. The ultimate result was the Bosch high-voltage magneto. The company registered a patent on this epoch-making system on 7 January, 1902, in the same year that the first units were delivered to customers in the automotive industry. At the same time, Bosch embarked upon the development and manufacture of yet another vital ignition component, the spark plug, an event which celebrated its 100th anniversary in 2002. This brochure from our ?automotive technology? series starts with a thumbnail sketch tracing the evolution of ignition systems. It then proceeds to the design and operation of modern inductive ignition systems as installed in current passenger cars with spark-ignition engines. Two of this brochure's central topics are the ignition coil and the spark plug, to which special sections have been devoted. These sections furnish detailed descriptions of the design, versions and operating concepts of various coil and plug models. Also included are descriptions of the particular demands imposed by direct gasoline injection and their implications for the selection of ignition components. The chapter on service technology offers insights into the methods employed to test ignition systems along with an overview of the test equipment used in service operations.
