Title:
内燃機関における空気燃料混合気の点火装置
Document Type and Number:
Japanese Patent JP2005536684
Kind Code:
A
Abstract:
A device is described for igniting an air-fuel mixture in an internal combustion engine using a high-frequency electric power source having a coaxial waveguide structure ( 5 ) into which the high-frequency electric power may be coupled and whose one end protrudes into the individual combustion chamber of a cylinder of the internal combustion engine. The one end of the coaxial waveguide structure ( 5 ) is designed as an igniter ( 7 a) in such a way that, when a voltage potential is applied, a field structure ( 22 ), protruding into the combustion chamber, and thus a free-standing plasma in the air-fuel mixture at the inner conductor ( 7, 7 a), projecting from the waveguide structure, is generatable via an abrupt and/or smooth cross-section change ( 21 ) of the inner conductor ( 7 ) and/or the outer conductor ( 6 ).
