Beschreibung
Zusammenfassung:	FIELD: electrical equipment of internal-combustion engines; fuel injection in carburetor and injection-type engines. ^ SUBSTANCE: proposed spark plug has body accommodating insulator with central stick electrode; butt-end of body dipped into engine cylinder has hemispherical depression whose center is on longitudinal horizontal axis and tangential holes are made on cylindrical part of body between butt-end and threaded surface of body to provide communication between precombustion chamber and engine cylinder space; depression depth h is interrelated with hemisphere radius R by expression 0.2
