Ama-Spark plugs, ajwayele owaziwa ngokuthi ama-plugs omlilo, azosebenza njengokuphuma kokuphuma kwamandla okuhola okuphezulu okuvela ku-high-voltage eholwa yi-electrodes yama-electrork ama-spark, akhiqize izinhlansi zikagesi zokukhipha umxhwele we-cylinder. Izimo eziyisisekelo zenjini yokusebenza ephezulu: I-High Energy Exerter Stable Spark, ingxube eyunifomu, isilinganiso esiphakeme sokucindezela. Izimoto ezinezinjini zangaphakathi zokuhlanganisa zisebenzisa uphethiloli kaphethiloli kanye nodizili. Emakethe yemoto yaseChina, izimoto zikaphethiloli zihlala ingxenye enkulu. Izinjini zikaphethiloli zihlukile ezinjini zedizili ngoba uphethiloli unendawo ephakeme yokulahla (cishe ama-400 degrees), adinga ukuthi ucindezelwe ama-digres ukudonsa ingxube. Ngokukhipha phakathi kwama-electrodes ukukhiqiza ama-spark, injini kaphethiloli ngokusebenzisa uphethiloli kanye nophethiloli wengxubevange wesikhathi sokukhiqiza amandla okukhiqiza amandla, ukuze kuthi lapho kunesimo sokushisa esiphakeme kakhulu ukukhiqiza amandla okuzenzakalelayo, ukuze kudingeke ukuthi kube nokukhanya kwayo okuphezulu kubalulekile ukusebenzisa "umlilo" ukusula. Lapha okulahla i-spark kungukusebenza kwe- "spark plug"
