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