The bushing imazunguliridwa - kuwonongeka kwakukulu kwa injini
Bushings ndi zinthu zofunika za injini iliyonse. Ngati alephera, njingayo iyenera kukonzedwanso kapena kusinthidwa ndi yatsopano.
Dongosolo la crank la injini limathandizidwa ndi mayendedwe a manja. Zolemba za shaft zimazunguliridwa ndi tchire. Mapangidwe a bushings si ovuta. Awa ndi mbale zozungulira zozungulira zokhala ndi kuuma koyenera, zomwe zimatha kuperekedwa ndi ma tchanelo ndi mabowo kuti zitsimikizire kuti zinthu zozungulira zimadzaza bwino.
Zomera zimatha kuvala zachilengedwe. Kumanga koyenera, zipangizo zoyenera, kugwira ntchito moyenera ndi kukonza bwino zimabweretsa mazana a zikwi ngati si mamiliyoni a mailosi.
Sikuti nthawi zonse moyo umalemba zolemba zabwino. Zomera, ngakhale kuti ndizosavuta kupanga, zimatha kuwonongeka. Ndikokwanira kuchedwetsa tsiku losintha mafuta kapena osayang'ana momwe alili - mafuta ogwiritsidwa ntchito kapena ocheperako amatha kufulumizitsa kwambiri mavalidwe a tchire.
Komanso sakakamiza injini kukakamizika. Vuto silimangogwiritsa ntchito molakwika kuthamanga kwambiri kapena kuyendetsa galimoto kwanthawi yayitali mumsewu waukulu ndi chopondapo cha gasi pansi. Kukweza kwambiri kwa injini yozizira kapena kuyesa kuthamanga kuchokera kumayendedwe otsika pamagiya apamwamba ndikowopsanso - crankshaft ndi zolumikizira ndodo zimalemedwa ndi katundu wambiri.
Panevkom imathanso kukhudza kuwongolera kwakukulu kwa injini. Ma bushings okhazikika sangathe kupirira kuchuluka kwa torque. Zachidziwikire, m'mabuku amakampani apadera, mutha kupeza ma bushings omwe amasinthidwa kuti atumize mphamvu zazikulu.
Kuzungulira kwa manja kungayambitsidwe ndi kusewera kwambiri kapena kutayika kwamafuta komanso kuwonjezereka kwamphamvu kwamakangana pakati pa mawondo ndi shaft. Mavuto a acetabular nthawi zambiri amakhala nsonga ya madzi oundana. Pambuyo pochotsa injini, nthawi zambiri zimakhala kuti crankshaft imapindika. Zikavuta kwambiri, gawo la powertrain likhoza kuwonongeka. Pankhani yamagalimoto odziwika azaka zambiri, kukonzanso kwathunthu kwa injini nthawi zambiri kumanyalanyazidwa - kugula injini yogwiritsidwa ntchito ndikopindulitsa kwambiri pazachuma.
Injini zina zimadziwika chifukwa cha zomangira zozungulira zolumikizira. Izi zikuphatikizapo 1.5 dCi ndi 1.9 dCi ya mgwirizano wa Renault-Nissan, Fiat ndi Lancia 1.8 16V, Alfa Romeo 1.8 ndi 2.0 TS kapena BMW M43 unit.
Kuzindikira kolondola kwa mkhalidwe wa mayendedwe sikutheka popanda kusokoneza injini. Kuyandikira kwa chiyambi cha mapeto kumawonetsa maonekedwe a zitsulo zachitsulo mu mafuta a injini. Ndiosavuta kunyamula mukasintha mafuta. Amapezekanso pamwamba pa fyuluta yamafuta. Phokoso lalikulu lachitsulo pamene kuchuluka kwa injini kumasintha kungasonyeze tchire lalikulu.
