Ignition device for rotary piston internal combustion engine, comprises high voltage generator for generating electric arc at center electrode of spark plug in spark plug borehole in shell housing with spark plug housing

摘要

The ignition device comprises a high voltage generator for generating an electric arc at a center electrode (13) of a spark plug (2) in a spark plug borehole (8) in a shell housing (1) with a spark plug housing (6), a threaded portion (7), and an insulator (9), which is surrounded by a hollow chamber (10). The spark plug borehole in the shell housing has a constriction (11) close to a trochoid runway (4). An independent claim is also included for a spark plug comprises an ignition channel.
