Arrangement for igniting fuel mixture in motor vehicle engine has ignition plugs arranged in pairs in engine block and ignition takes place between center electrodes of the two ignition plugs

摘要

The arrangement has ignition plugs (2) arranged in pairs in the engine block and ignition takes place between the center electrodes (3) of two ignition plugs. The two center electrodes are of different polarity. The width of the spark gap (4) is selected depending on compression pressure, component geometry and/or the composition of the fuel mixture for the maximum applied voltage between the center electrodes.
