FIELD: engines and pumps.SUBSTANCE: ignition plug is fitted with at least one additional lateral electrode designed similarly to the first one and located symmetrically opposite to it with reference to the central electrode axis, and the end face surfaces of both lateral electrodes are inclined at sharp angle to the central electrode axis towards one or another side from the normal line to the axis of this electrode and are formed by the second order surface, for example a cone the axis of which coincides with the central electrode axis, or end face surfaces are implemented in the same plane passing through the flat end face of the central electrode perpendicular to its axis.EFFECT: increase of service life of ignition plugs and reliability of ignition of fuel-air mix.3 cl, 6 dwg |
