Cummins QSNT855 Injini Musangano
Portduct application
NTA855 ine zvakawanda zvekushandisa.Inogona kuve yakagadzirwa nejenareta seti.Semuenzaniso, inogona kuve yakagadzirwa nejenareta seti yezvikepe.Inogona zvakare kuve yakashongedzerwa nemotokari.Kana yakashongedzerwa nemotokari, inonyanya kuve muchina wekuvaka, mabulldozer, vanochera, cranes, nezvimwe.
Dhizaini yepamusoro uye yakavimbika kuita:
Cylinder block: yakagadzirwa nepamusoro-simba alloy cast iron, ine yakanaka kuomarara, yakaderera vibration uye yakaderera ruzha.
Cylinder head: Four-valve design per cylinder, optimized air/fuel musanganiswa ratio, zvinobudirira kuvandudza kupisa uye kubuda;musoro mumwe pahumburumbira, kugadzirisa kuri nyore.
Camshaft: Iyo imwe chete camshaft dhizaini inogona kunyatso kudzora vhavha uye jekiseni nguva, uye yakagadziridzwa cam profile inogona kuderedza simba rekuita uye kugadzirisa kuvimbika uye kusimba.
Crankshaft: Integral crankshaft yakagadzirwa nesimbi yakakwirira-yakasimba.Iyo induction kuomesa maitiro efillet uye jenari inogona kuve nechokwadi chepamusoro chekuneta kwesimba re crankshaft.
Piston: Uchishandisa ichangoburwa aluminium alloy casting tekinoroji, dhizaini ye ω-yakaita musoro uye siketi yakaita sedhiramu inogona kubhadhara kuwedzera kwekupisa uye kuputika kuti ive nechokwadi chekuenderana.
Iye zvino tinotora NTA855-G1 semuenzaniso, ongorora iyo chaiyo paramita yeinjini iyi
