I-Diesel Injector Fuel Injector 0445120240 Bosch for Case / New Holland Cummins Engine

Ukuze kunwetshwe impilo yesevisi yomjovo futhi kuthuthukiswe isivinini sokuvala sevalve yenaliti, umjovo ophansi we-inertia kufanele usetshenziselwe injini yedizili enejubane lokujikeleza elingaphezu kuka-3000r/min. Kodwa i-inertia ephansi ye-spring diameter ye-inertia incane, ukucindezeleka komshini kanye nokucindezeleka okushisayo kukhulu, ngakho izidingo zekhwalithi yasentwasahlobo ziyathuthukiswa uma kuqhathaniswa. Ukwengeza, ukuze kuqhutshekwe nokunciphisa inertia yokunyakaza, indlela yokunciphisa ububanzi be-valve yenaliti ingasetshenziswa ukuze kuqhutshekwe nokunciphisa inertia yokunyakaza komjovo kaphethiloli. I-inertia ephansi yomjovo kaphethiloli ilungele ukuvimbela i-cavitation ebusweni besihlalo senaliti, ukugwema ukunqwabelana kwekhabhoni ebhajwe kubhobho likaphethiloli okubangelwa ukubuya kwegesi, kanye nomjovo obambezelekile obangelwa ukusabela okungasebenzi kwevalvu yenaliti. Isibonelo, injini yedizili ye-YG6105QC isebenzisa isijojo sikaphethiloli esine-inetia ephansi.

Ingcindezi yomjovo (force j) yenjini kadizili iyipharamitha ebalulekile yesistimu yokujova uphethiloli. Uma amanye amapharamitha wohlelo lomjovo eqinisekile, ingcindezi yomjovo inqunywa ingcindezi yomjovo. Umfutho ojwayelekile womjovo wenjini kadizili ongu-12150L ungama-MPa angama-21, kodwa uzokwehla kancane kancane ngokukhula kwempilo yesevisi. Ngemva kokuphelelwa yisikhathi kwesevisi, ngokuvamile iyehla ibe ngu-17.3 ~ 19.4 MPa. Ukwehla kwengcindezi yokuqala kuzoqhubeza umjovo, kwandise isikhathi somjovo, kwandise ukutholakala kukawoyela, futhi kuholele ekwenyukeni kwamandla enjini kadizili. Ngasikhathi sinye, izinga lomjovo kaphethiloli liyehla, uhla lwemishayo kawoyela luyancishiswa, ububanzi obumaphakathi bezinhlayiyana zikawoyela ze-v buyanda, izinga lokufafaza liyawohloka, ukusha kuyawohloka, okuholela ekwehleni komnotho wenjini yedizili. Ngaphezu kwalokho, ukwehla kokucindezela kokuqala nakho kulula ukwenza idiphozi ye-carbon ekhanda le-valve yenaliti.
