Diesel Injector Fuel Injector 0445120064 0445120136 0445120137 Bosch for Renault Engine 240 Premium II

Ubulukhuni obuncinci bamasuntswana akrobayo adubulayo enza ukuba unyango lomphezulu wentwasahlobo lungadluli;· Ukukhathala kwe-fracture akhawunti malunga ne-1.7% yokungaphumeleli ngokupheleleyo, kwaye abanye baphumla ngokukhathala.· Ukuphumla ukudinwa bekusoloko kuyingxaki edida ishishini lasentwasahlobo.Ekubeni izinyithi azikho i-elastomer ngokupheleleyo, i-micro-deformation (i-creep) iya kwenzeka naphantsi kwesenzo soxinzelelo olungaphantsi komda we-elastic, kwaye impembelelo ye-deformation esisigxina kwi-drop pressure yokuvula i-injector ngokubanzi i-0.5 Ngaphandle kwe-MPa, ukuhla koxinzelelo ubukhulu becala kubangelwa ukunxitywa kwebhola yentsimbi okanye i-sphere kumsila wevalve yenaliti kunye nentonga ye-ejector, kunye nefuthe layo kwi-drop drop pressure phakathi kwe-0.5 kunye ne-2.5 MPa.

(2) Ukunxitywa kweegaskets ezisicaba: (1) Iigaskithi ezisicaba zineentsimbi, ukuya kuthi ga kwi-0.4mm;②Imathiriyeli ye-gasket ecaba ithambile, intsimbi eqhelekileyo ephantsi kwekhabhoni, kunye nokuqina HRC47 ~ 54 isiphelo sentlakohlaza yoqhagamshelwano kulula ukuyinxiba kunye noguquko.

(3) intonga yokugqogqa.Isikrufu sokulawula uxinzelelo (okanye umkhono wesijiyu) kunye noxinzelelo lokulawula isikrufu sobuso besiphelo senqwelomoya ukunxitywa kwenqwelomoya :40% yesitofu se-fuel ibonakala igugile apha.Kukho izizathu ezibini:①ukusetyenzwa komphezulu woqhagamshelwano kurhabaxa kakhulu, iRa 12.50 Hn, kubangele ukuhla koxinzelelo olungaphezulu kwe-1 MPa;(2) Inqwelo-moya yoqhagamshelwano ayilingani, nto leyo ebangela ukuba ubuso obungalinganiyo entwasahlobo bubangele ukunxitywa kwebhanti eqaqambileyo, ukunxiba ubunzulu obuninzi ukuya kuthi ga kwi-0.15mm.

(4) Impembelelo yokucoceka kwesitofu se-fuel: Ngenxa yokuba impembelelo yokutshatyalaliswa kwezixhobo zokulahla i-fuel injector yabakhiqizi abaninzi basekhaya abanakukwazi ukuhambelana neemfuno zemigangatho yelizwe, kukho inani elithile leenwele kunye ne-abrasive processing kumzimba wesitofu se-fuel. ibangela ukuguga okungaqhelekanga kweendawo zokudityaniswa kwesitofu se-fuel, okukhokelela ekwandeni kococeko olufanelekileyo, ukuwohloka kwetywina kunye nokwehla koxinzelelo.
