FIELD: engines and pumps.
SUBSTANCE: invention relates to prechamber spark-plug. Proposed spark-plug comprises mid electrode 2, at least one side electrode 3 spaced from said mid electrode 2 to make spark gap 7 and at least one via 9 in prechamber cover 4. Note here that said side electrode 3 has inner peripheral surface facing said mid electrode and outer peripheral surface directed therefrom. Note that said inner peripheral surface in prechamber lengthwise direction features concaved shape subjected to stretching stress. Note that said outer peripheral surface in prechamber lengthwise direction features convexed shape subjected to compressing stress.
EFFECT: longer life.
