I-China Yenze I-Valve Yevaluvu Yokulawula I-Valve Evamile Evamile Yesitimela F00RJ01924 ye-Injector 0445120296 & 0445120102

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, kanye ne-Siemens VDO (manje ephethwe yi-Continental AG)

Ezinhlelweni zikaloliwe ezivamile, iphampu enengcindezi ephezulu igcina indawo yokugcina uphethiloli 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 inikeza ama-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 okucindezela kukaphethiloli 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).
