Iprototype yesistimu yezitimela ezivamile yezinjini zezimoto yathuthukiswa ngasekupheleni kwawo-1960 ngu-Robert Huber waseSwitzerland, futhi ubuchwepheshe babuye bathuthukiswa nguDkt. Marco Ganser e-Swiss Federal Institute of Technology eZurich, kamuva kwe-Ganser-Hydromag AG e-Oberägeri.
Uhlelo lwesitimela olujwayelekile lufanele zonke izinhlobo zezimoto zomgwaqo ezinezinjini zikadizili, kusukela ezimotweni zasedolobheni (njengeFiat Panda) kuya ezimotweni eziphezulu (njenge-Audi A8). Abahlinzeki abakhulu bezinhlelo zesimanje zikaloliwe ezivamile yi-BOSCH, Delphi, Denso, ne-Siemens VDO (manje ephethwe yi-Continental AG)
Ezinhlelweni zikaloliwe ezivamile, iphampu enomfutho ophezulu wegazi igcina inqolobane kaphethiloli lapho kunengcindezi ephezulu-kufika nangaphezulu kwamabha angu-2,000 (200 MPa; 29,000 psi). Igama elithi "isitimela esivamile" libhekisela eqinisweni lokuthi wonke ama-injection kaphethiloli ahlinzekwa yisitimela esivamile sikaphethiloli esingeyona into engaphezu kwe-accumulator yokucindezela lapho uphethiloli ugcinwa khona ngomfutho ophezulu. Le accumulator inikezela ngama-injection kaphethiloli amaningi anophethiloli wengcindezi ephezulu. Lokhu kwenza kube lula injongo yephampu yomfutho ophezulu ngoba idinga kuphela ukugcina ukucindezela okuqondiwe (okungaba ngomshini noma okulawulwa ngogesi). Ama-injection kaphethiloli ngokuvamile alawulwa yiyunithi yokulawula injini (ECU). Uma ama-injection kaphethiloli esebenza ngogesi, ivalvu edonsa amanzi (ehlanganisa umlomo wombhobho ne-plunger) ivulwa ngomshini noma ngomshini wokudonsa amanzi bese uphethiloli ufuthwa kumasilinda ngomfutho ofunekayo. Njengoba amandla omfutho kaphethiloli egcinwa ukude futhi ama-injection acushwe ngogesi, ingcindezi yomjovo ekuqaleni nasekupheleni komjovo iseduze kakhulu nokucindezela ku-accumulator (isitimela), ngaleyo ndlela kukhiqiza izinga lomjovo wesikwele. Uma i-accumulator, iphampu, kanye namapayipi kulinganiswa ngokufanelekile, ingcindezi yomjovo kanye nesilinganiso kuzolingana kumcimbi ngamunye womjovo omningi.
Udizili wesitimela ovamile wesizukulwane sesithathu manje unezijovo ze-piezoelectric ukuze uthole ukunemba okuthuthukisiwe, nokucindezela kukaphethiloli kufika kumabha angu-2,500 (250 MPa; 36,000 psi).
