Technique and spark plug to ignite very lean fuel air mixtures, particulary for gas engines

摘要: A method and a spark plug construction to ignite very lean fuel air mixtures with the aid of an ignition chamber separate ignition, which is arranged in main combustion internal engine, connected 20 through transfer channels 21. Transfer may be provided proceed tangentially, whereby rich admixtures or additional brought, valve timed, area at least one channel 21 outside supply 24. During compression stroke mixture pressed into 16 channels, results good intermixing admixture due turbulent movement long path gap. This guarantees safe ignition.
