Sparks of Genius for the Gasoline Engine of Tomorrow

November 6, 2012 // Berlin. IAV is holding the first international conference on “Ignition Systems for Gasoline Engines” in Berlin on November 12 and 13. Attention will be centering on the question of whether the classic spark plug needs to be replaced with alternative systems in tomorrow’s gasoline engines. Experts from manufacturers, component suppliers and research will be providing a glimpse at the latest progress being made by the developers.

By 2020, CO2 emissions from the passenger car fleets are to fall to 95 grams per kilometer. At the moment, manufacturers are improving the efficiency of their engines mainly by using a combination of reduced displacement and supercharging at significantly higher mean pressure (downsizing). Further optimization potential could be harnessed by diluting the cylinder charge – but this involves shifting ignition limits. The latest research results show that this can only be done by replacing the classic spark plug. In conjunction with broad variation of mixture quality and high EGR rates, reliable and precise ignition can only be guaranteed with alternative systems.

IAV presents criteria for configuring corona ignition systems

The first international conference on “Ignition Systems for Gasoline Engines” will be looking at alternatives to the classic spark plug, matters concerning all aspects of combustion thermodynamics, methods for simulating and developing flame kernels and propagation as well as algorithm development for controlling ignition.

IAV is working on a completely new system for igniting fuel on the basis of CORONA discharge. This conference will be presenting design criteria for using corona ignition systems in combustion engines. In contrast to the spark plug, this produces a far higher number of ignition centers spread over a large area in the combustion chamber. Even with lean mixtures, this results in complete and efficient combustion and is capable of cutting gasoline-engine fuel consumption by as much as ten percent. A conference paper will be describing how the spark position can be optimized for supercharged tumble-assisted combustion processes while taking account of in-cylinder flow.

Experts from manufacturers (including Volkswagen, Daimler and Toyota), component suppliers (such as Delphi, AVL and BERU) as well as universities (Vienna University of Technology, Stuttgart University and Aachen University of Applied Sciences) will also be talking about the latest developments taking place on the ignition systems front.
