Ignition Systems For Gasoline Engines

The volume includes selected and reviewed papers from the 3rd Conference on Ignition Systems for Gasoline Engines in Berlin in November 2016. Experts from industry and universities discuss in their papers the challenges to ignition systems in providing reliable, precise ignition in the light of a wide spread in mixture quality, high exhaust gas recirculation rates and high cylinder pressures. Classic spark plug ignition as well as alternative ignition systems are assessed, the ignition system being one of the key technologies to further optimizing the gasoline engine.

For decades, scientists and engineers have been working to increase the efficiency of internal combustion engines. For spark-ignition engines, two technical questions in particular are always in focus: 1. How can the air/fuel mixture be optimally ignited under all possible conditions? 2. How can undesirable but recurrent early and self-ignitions in the air/fuel mixture be avoided? Against the background of the considerable efficiency increases currently being sought in the context of developments and the introduction of new fuels, such as hydrogen, methanol, ammonia and other hydrogen derivatives as well as biofuels, these questions are more in the focus than ever. In order to provide a perfect exchange platform for the community of combustion process and system developers from research and development, IAV has organized this combined conference, chaired by Marc Sens. The proceedings presented here represent the collection of all the topics presented at the event and are thus intended to serve as an inspiration and pool of ideas for all interested parties.

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 brochures 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. Covers: -Historical retrospective-Design of inductive ignition systems-Ignition coils and spark plugs-Service technology

The call for environmentally compatible and economical vehicles necessitates immense efforts to develop innovative engine concepts. Technical concepts such as gasoline direct injection helped to save fuel up to 20 % and reduce CO2-emissions. Descriptions of the cylinder-charge control, fuel injection, ignition and catalytic emission-control systems provides comprehensive overview of today ́s gasoline engines. This book also describes emission-control systems and explains the diagnostic systems. The publication provides information on engine-management-systems and emission-control regulations.
