Abstract
An ignition device 11 for a multi-cylinder internal combustion engine is to be designed so that it operates reliably even under conditions of vibration acceleration of the internal combustion engine. Ignition device 11 has, depending on the number of cylinders of the internal combustion engine, rod-shaped ignition coils 12. An end section 22 of each ignition coil 12 is formed by a part of a core 23 of ignition coil 12 that protrudes from a housing 20 of ignition coil 12. A damper 29 is mounted on the part of core 23. The other end section 21 of ignition coil 12 is formed by a high-voltage dome 27, which is mounted in a socket 39 made of elastic material and placed in a spark plug pit 15 of a cylinder head 13 of the internal combustion engine. Ignition device 11 is elastically held by fastening element 33 and secured at both end sections 21, 22 on cylinder head 13 of the internal combustion engine. The high voltage is transferred in an elastic manner to a corresponding spark plug 16 via a high-voltage contact element 48, designed as a spring.
