Eminyakeni yamuva, izicelo ze-fuel injector pump 294000-1691 zishintshile ukuze zisebenze ngaphansi kwezimo ezicindezelayo, okuye kwanda izidingo zokushisa ezishisayo. Kwezinye izimo, umsindo udinga ukuncishiswa, futhi nokugcinwa kwamandla kuyadingeka, okwenza iphampu yomjovo kaphethiloli ibhekane nomsebenzi onzima kakhulu. Ngakho-ke, lokhu kube ngesinye sezizathu ezinkulu zokuthi kungani siqhubeka nokuthuthukisa ukusebenza kwamaphampu ethu okujova uphethiloli.
