I-Cummins QSNT855 Engine Assembly
Isicelo se-Portduct
I-NTA855 inokusetshenziswa okuningi.Kungenziwa ifakwe amasethi generator.Isibonelo, ingafakwa ngamasethi e-generator emikhumbi.Ingase futhi ifakwe izimoto.Uma ifakwe izimoto, ikakhulukazi imishini yokwakha, ama-bulldozers, ama-excavators, ama-cranes, njll.
Idizayini ethuthukisiwe nokusebenza okuthembekile:
I-cylinder block: eyenziwe nge-high-strength alloy cast iron, enokuqina okuhle, ukudlidliza okuphansi nomsindo ophansi.
Ikhanda le-cylinder: Idizayini enamavalvu amane isilinda, isilinganiso sengxube ye-air/fuel elungiselelwe, sithuthukisa ngempumelelo ukusha nokukhipha umoya;ikhanda elilodwa isilinda, ukugcinwa lula.
I-Camshaft: Idizayini eyodwa ye-camshaft ingalawula ngokunembile isikhathi se-valve nesikhathi somjovo, futhi iphrofayili yekhamera eyenziwe kahle inganciphisa amandla omthelela futhi ithuthukise ukwethembeka nokuqina.
I-Crankshaft: I-crankshaft ehlanganisiwe eyenziwe ngensimbi ekhandiwe enamandla amakhulu.Inqubo yokwenza ukuqina kwe-induction ye-fillet kanye nejenali ingaqinisekisa amandla aphezulu okukhathala kwe-crankshaft.
I-Piston: Ngokusebenzisa ubuchwepheshe bakamuva be-aluminium alloy casting, idizayini yekhanda elimise okuka-ω nesiketi esimise okomgqomo singanxephezela ukunwetshwa nokufinyela okushisayo ukuze kuqinisekiswe ukulingana okuhle.
Manje sithatha i-NTA855-G1 njengesibonelo, sihlaziye imingcele ethile yale injini
