Isitofu se-Diesel Fuel Injector 0445120387 iyahambelana ne-Bosch injector

Uyilo lwesakhiwo se-accumulator fuel injection

I-accumulator cavity ibandakanya i-accumulator orifice kunye ne-accumulator cavity. Umngxuma we-throttle ubekwe kuluntu lwe-accumulator cavity, evelisa isiphumo esinamandla sokuntywila kwinkqubo yokutofa kweoyile, inqanda ukuguquguquka koxinzelelo oluveliswa yi-injector ukuba lusasazeke kwinkqubo, kwaye ikwanciphisa ifuthe lokuguquguquka koxinzelelo oluveliswa yi. ezinye ii-injector kwi-injector. Igumbi le-accumulator lifumaneka kwintloko ye-injector, eyona nto isetyenziselwa ukulungiselela ukufakwa kwepetroli nge-injector. Idlala indima ye-accumulator kwaye ithatha ukuguquguquka koxinzelelo olubangelwa ukuvulwa kunye nokuvalwa kwevalve yenaliti kwi-injector, ehambelana nokulawulwa ngokuchanekileyo kwenaliti. Ngethuba lokutofa kwepetroli, ubuninzi be-fuel ye-injector kufuneka bongezwe kuphela emva kwesitofu ngasinye. Ke ngoko, ukuhla koxinzelelo kunye nencopho yoxinzelelo kumbhobho ekupheleni kwesitofu kunokugcinwa ngaphakathi koluhlu oluchaziweyo ngokuyila igumbi le-accumulator ngomthamo ofanelekileyo, onokuqonda ulawulo oluchanekileyo lwesitofu sobuninzi bombhobho ngexesha ngalinye kwaye ngaloo ndlela ufezekise. injongo yokunciphisa ubungakanani benaliti engalinganiyo yesilinda ngasinye.

(1) Ummandla we-cross-sectional orifice we-accumulator kunye nomthamo we-accumulator unempembelelo enkulu kwiimpawu zokuhamba kwe-accumulator injector nozzle.

(2) Ngokunyuka kwendawo ye-orifice, i-volume fraction yegesi kwi-orifice iyanda kwaye umphumo we-cavitation uphuculwe; Isantya sokuhamba kwamafutha siyancipha kwaye ukuphuma kwe-outlet kuyancipha.

(3) Xa umthamo wegumbi le-accumulator ukhula, umphumo we-cavitation uphuculwe, kwaye umthamo we-fuel bubbles emgodini uba mkhulu; I-petroli enesantya esiphezulu ithatha indawo eninzi emngxunyeni, kwaye isantya samafutha ezantsi komngxuma siyancipha ngokuthe ngcembe, kwaye utshintsho lwalo alubonakali njengeqhezu lomthamo.
