Q: Uyini umehluko phakathi kwephampu yesidingo kanye nephampu ye-bypass kuzifafazi?

A: Amaphampu adingekayo avalwa ngokuphelele lapho i-trigger ivala, kuncike ekushintsheni kokucindezela ukuze kuphule isekethe kagesi. Amaphampu e-Bypass ayaqhubeka nokusebenza ngisho nalapho i-trigger ivaliwe; bahambisa uketshezi olunomfutho ngaphakathi emuva ethangini ukuze balondoloze umfutho wesistimu ngaphandle kokumisa injini.
