I-injector ye-Diesel Fuel Injector 0445120240 Bosch for Case / New Holland Cummins Injini

Ukuze ukwandise ubomi benkonzo ye-injector kunye nokuphucula isantya sokuvala i-valve yenaliti, i-injector ephantsi ye-inertia kufuneka isetyenziswe kwi-injini ye-diesel kunye nesantya sokujikeleza esikhulu kune-3000r / min. Kodwa i-inertia ephantsi ye-injector ye-spring-diameter incinci, uxinzelelo lomatshini kunye noxinzelelo lwe-thermal lukhulu, ngoko ke iimfuno zomgangatho wentwasahlobo ziphuculwe. Ukongezelela, ukwenzela ukunciphisa ngakumbi i-inertia yokunyakaza, indlela yokunciphisa i-diameter ye-valve yenaliti ingasetyenziselwa ukunciphisa ngakumbi i-inertia yentshukumo ye-injector fuel. I-inertia ephantsi ye-injector ye-fuel ilungile ekukhuseleni i-cavitation kumphezulu wesihlalo senaliti, ukuphepha ukuqokelelwa kwekhabhoni ebambekile kwi-nozzle ye-fuel ebangelwa ukubuya kwegesi, kunye nokulibaziseka kwenaliti ebangelwa kukungasebenzi kakuhle kwevalve yenaliti. Umzekelo, i-YG6105QC injini yedizili isebenzisa isitofu esisezantsi se-inertia.

Uxinzelelo lwenaliti (i-force j) ye-injini ye-diesel luphawu olubalulekileyo lwenkqubo yokutofa kwamafutha. Xa ezinye iiparameters zenkqubo yokutofa ziqinisekile, uxinzelelo lwenaliti lumiselwa ngoxinzelelo lwenaliti. Uxinzelelo oluqhelekileyo lwesitofu lwe-12150L injini ye-diesel yi-21 MPa, kodwa iya kuncipha ngokuthe ngcembe ngokukhula kobomi benkonzo. Emva kokuphelelwa kwenkonzo, ihla iye kuthi ga kwi-17.3 ~ 19.4 MPa. Ukuhla koxinzelelo lokuqalisa kuya kuqhubela phambili inaliti, konyuse ixesha lokutofa, ukonyusa unikezelo lweoyile, kwaye kukhokelele ekonyukeni kwamandla enjini yedizili. Kwangaxeshanye, izinga lokutofa kwepetroli liyehla, uluhlu lwe-oyile luncitshiswe, umyinge we-avareji ye-oyile ye-v iyanyuka, umgangatho wokutshiza uwohloka, ukutsha kuyancipha, okukhokelela ekuhlahleni koqoqosho lwe-injini ye-diesel. Ukongeza, ukuqala ukwehla koxinzelelo kulula ukwenza idiphozithi yekhabhoni kwintloko yevalve yenaliti.
