I-China Yenze iNdibano eNtsha yoLawulo lweValve yesiBonelo esiQhelekileyo sikaLoliwe F00RJ01924 ye-Injector 0445120296 & 0445120102

Iprototype yenkqubo kaloliwe eqhelekileyo yeenjini zeemoto yaphuhliswa ekupheleni kweminyaka yoo-1960 nguRobert Huber waseSwitzerland, kwaye iteknoloji yaphuhliswa ngakumbi nguGqr Marco Ganser kwiSwiss Federal Institute of Technology eZurich, kamva yeGanser-Hydromag AG e-Oberägeri.

Inkqubo kaloliwe eqhelekileyo ifanelekile kuzo zonke iintlobo zeemoto zendlela ezineenjini zedizili, ukusuka kwiimoto zedolophu (ezifana neFiat Panda) ukuya kwiimoto ezilawulayo (ezifana ne-Audi A8). Ababoneleli abaphambili beenkqubo zikaloliwe eziqhelekileyo zangoku yiBOSCH, Delphi, Denso, kunye ne-Siemens VDO (ngoku ephethwe yi-Continental AG)

Kwiinkqubo zikaloliwe eziqhelekileyo, impompo yoxinzelelo oluphezulu igcina i-reservoir yamafutha kuxinzelelo oluphezulu-ukuya kuthi ga nangaphezulu 2,000 imivalo (200 MPa; 29,000 psi). Igama elithi "umzila kaloliwe oqhelekileyo" libhekisa kwinto yokuba zonke ii-injector zepetroli zibonelelwa ngomzila kaloliwe oqhelekileyo wamafutha ongeyonto ngaphandle kwe-accumulator yoxinzelelo apho isibaso sigcinwa kuxinzelelo oluphezulu. Le accumulator ibonelela ngee-injection ezininzi zepetroli nge-fuel yoxinzelelo oluphezulu. Oku kwenza lula injongo yempompo yoxinzelelo oluphezulu kuba ifuna kuphela ukugcina uxinzelelo olujoliswe kuyo (mhlawumbi ngoomatshini okanye ukulawulwa ngombane). Izitofu zamafutha ngokuqhelekileyo zilawulwa yiyunithi yokulawula injini (ECU). Xa ii-injection zamafutha zisebenza ngombane, ivalve yehydraulic (ebandakanya umlomo wombhobho kunye neplunger) ivulwa ngoomatshini okanye ngehydraulically kwaye i-fuel itshizwe kwiisilinda ngoxinzelelo olufunekayo. Ekubeni amandla oxinzelelo lwamafutha egcinwa kude kwaye ii-injection zisebenza ngombane, uxinzelelo lwenaliti ekuqaleni nasekupheleni kwesitofu lusondele kakhulu kuxinzelelo lwe-accumulator (umzila), ngaloo ndlela uvelisa ireyithi yesikweri sokutofa. Ukuba i-accumulator, impompo, kunye ne-plumbing zilinganiswe ngokufanelekileyo, uxinzelelo lwe-naliti kunye nomlinganiselo uya kufana kwisiganeko ngasinye sokutofa.

Isizukulwana sesithathu[esingaqondakaliyo] iidizili zikaloliwe eziqhelekileyo ngoku zinee-injection ze-piezoelectric zokuchaneka okwandisiweyo, kunye noxinzelelo lwamafutha ukuya kuthi ga kwi-2,500 bar (250 MPa; 36,000 psi).
