Cummins QSNT855 Injini yeNdibano
Ukusetyenziswa kwemveliso
I-NTA855 inosetyenziso oluninzi.Inokuxhotyiswa ngeeseti zejeneretha.Ngokomzekelo, inokuxhotyiswa ngeesethi zejeneretha kwiinqanawa.Inokuxhotyiswa nangezithuthi.Ukuba ixhotyiswe ngezithuthi, ubukhulu becala oomatshini bokwakha, iibulldozers, abembi, iikhreyini, njl.
Uyilo oluphezulu kunye nokusebenza okuthembekileyo:
Ibhlokhi ye-cylinder: yenziwe ngentsimbi ephezulu yamandla e-alloy, enokuqina okuhle, i-vibration ephantsi kunye nengxolo ephantsi.
Intloko ye-cylinder: Uyilo lwe-valve ezine nge-cylinder, ulungelelwaniso lomxube we-air / fuel mix, ngokufanelekileyo ukuphucula ukutshisa kunye nokukhutshwa;intloko enye kwisilinda, ukugcinwa lula.
I-Camshaft: Idizayini enye ye-camshaft inokulawula ngokuchanekileyo i-valve kunye nexesha le-injection, kwaye iphrofayili yekhamera ephuculweyo inokunciphisa amandla empembelelo kunye nokuphucula ukuthembeka kunye nokuqina.
I-Crankshaft: I-Integral crankshaft eyenziwe ngentsimbi ekhandiweyo yokuqina okuphezulu.Inkqubo yokwenza lukhuni kwe-fillet kunye nejenali inokuqinisekisa amandla aphezulu okudinwa kwe-crankshaft.
I-Piston: Ukusebenzisa iteknoloji ye-aluminium yamva nje yokuphosa i-alloy, idizayini ye-ω-shaped head and barrel-shaped skirt inokuhlawula ukwanda kwe-thermal kunye nokunciphisa ukuqinisekisa ukufaneleka kakuhle.
Ngoku sithatha i-NTA855-G1 njengomzekelo, sihlalutye iiparamitha ezithile zale injini
