Ikhwalithi Enhle Ethengiswa Kakhulu 0 445 110 699 Diesel Injector 0445110699 yakwaToyota

Isistimu yomjovo wesitimela diesel high-pressure common ihlanganisa i-hydraulic system kanye ne-electronic control system. Uhlelo lwe-hydraulic luhlukaniswe nge-low-pressure hydraulic system kanye ne-high-pressure hydraulic system. I-low-pressure hydraulic system ihlanganisa ithangi likaphethiloli, ipompo yokudlulisa uphethiloli, isihlungi samafutha kanye nepayipi likawoyela elinomfutho ophansi; uhlelo lwe-hydraulic high-pressure luhlanganisa ipompo yokucindezela okukhulu, isitimela se-fuel-pressure fuel, ama-injection kanye namapayipi kawoyela aphezulu; uhlelo lokulawula i-elekthronikhi (i-EDC ngamafuphi) luhlanganisa izinzwa, i-Electronic Control Unit (ECU), ama-actuator (okuhlanganisa ama-injection anamavalvu e-solenoid, ama-valve okulawula ukucindezela, amayunithi okulawula amapulaki akhanyayo, izilawuli ze-boost pressure, izilawuli zokujikeleza kwegesi ephumayo, ama-throttle valves, njll. ) kanye nezintambo zokuhlanganisa. Phakathi kwazo, i-injector, i-high-pressure pump, i-high-pressure fuel rail, kanye ne-electronic control unit izingxenye ezine ezibalulekile zesistimu yesitimela esivamile sikadizili.

Isijojo sikaphethiloliiyingxenye eyenza ama-athomu futhi isabalalise uphethiloli egunjini lokusha injini. Isikhathi somjovo kanye nobude bomjovo ojwayelekile wesitimela kubalwa ngokunembile iyunithi yokulawula ye-elekthronikhi bese inikezwa isignali, esuke ilawulwa ivalve ye-solenoid.

Umsebenzi weiphampu enengcindezi ephezuluukucindezela uphethiloli usuke esimweni somfutho ophansi uye endaweni enengcindezi ephezulu ngokusebenzisa i-plunger ukuze uhlangabezane nezidingo zesistimu kanye nenjini yokucindezela komjovo kaphethiloli kanye nevolumu yomjovo kaphethiloli.

Umsebenzi weujantshi wamafutha ocindezelwa kakhuluokokugcina uphethiloli ngenkathi kucindezela ukushintshashintsha kwengcindezi okubangelwa ukunikezwa kukaphethiloli kwepompo yokucindezela okuphezulu kanye nomjovo wesijovo sikaphethiloli ukuze kuqinisekiswe ukuzinza kwengcindezi yesistimu. Isitimela sikawoyela esinengcindezi ephezulu sijwayelekile kusilinda ngasinye futhi siwuphawu lwesistimu yezitimela ezivamile.
Iyunithi yokulawula ye-elekthronikhikufana nobuchopho benjini. Iqoqa amapharamitha okusebenza enjini, yenze izibalo nokucubungula ngokusekelwe kumamephu wesici agciniwe, futhi idlulisele amasignali kuma-actuator ukuze ibone ukulawula ukusebenza kwenjini, ukuhlonzwa kwamaphutha neminye imisebenzi.
