Abstract:

Innovative automotive engine concepts using direct gasoline injection demand for new ignition concepts. A novel spark-plug concept based on a microwave coaxial resonator is proposed, which generates a free-standing plasma flame. In this paper, design and realization of such a quarter-wave resonator at 2.45 GHz is presented and first experimental results are given showing the plasma-ignition properties of this resonator.
