I-Diesel Injector Fuel Injector Lr006496 A2c59513553 7h2q9K546CB 7h2q-9K546-CB ye Land Rover 276dt Siemens Injector

1.Impazamo eyenzekayo

I-atomization embi ye-injector ye-fuel (injection kwimigca emincinci okanye i-post-dripping) Ukubonakaliswa kwangaphandle kukuba ukushisa kwe-injini ye-diesel kuphezulu kwaye umsebenzi ubuthathaka. Inxalenye ephezulu yesilinda inesandi sokunkqonkqoza. Umbhobho wokukhupha ukhupha umsi omnyama. isandi

2 izizathu zokusilela

Ukusuka apha ngasentla, kunokubonwa ukuba i-atomization embi ye-injector ibangelwa ubukhulu becala uxinzelelo lwamafutha angena kwigumbi le-oyile ye-annular ye-injector iphantsi kunoxinzelelo lwe-injection yokuqala echazwe kumaxwebhu obugcisa kunye ne-viscosity yamafutha. ukuba phezulu kakhulu. Ezona zizathu ziphambili zezi (1) Ufakelo olungafanelekanga lwesitofu se-fuel okanye umphezulu wodibaniso oluchanekileyo umdaka okanye kukho ukuvuza kwerhasi ngasemva, okubangela ukuba isitofu sesibaso sibe shushu kakhulu kwaye kubangele ukungasebenzi kakuhle kwe-atom yesitofu samafutha (2) Ubume bobugcisa be isitofu samafutha. Zonke izibonakaliso zeoli yeoli ziyahlangabezana neemfuno. Ukuba i-atomization yamafutha ye-injector ye-fuel ihlwempuzekile, ininzi ibangelwa ukuwohloka kwemeko yobugcisa be-fuel injector. (3) Uxinzelelo olulawula intwasahlobo yesitofu sesibaso sincinci kakhulu. Ingabonwa ukuba i-fuel pressure in annular oil room of the injector change with pre-tighten force force by the pressure regulating spring. Ukuba i-pre-tighten force force ebekwe ngoxinzelelo olulawula intwasahlobo incinci kakhulu, i-fuel pressure in annular oil chamber iya kuba yincinci. Ubuninzi beemolekyuli ze-fuel buncinci kwaye uxinzelelo aluzange luqhubekile ukunyuka. Ubuninzi beemolekyuli zamafutha abukafikeleli kubuninzi obufanelekileyo ngexesha lokutofa. Ivalve yenaliti ityhalwa ivuleke ngamafutha kwaye i-fuel iyatofwa ngenxa yokuba ubuninzi beemolekyuli ze-fuel abukho phezulu, ngoko ke ukwanda kunye namandla okusasaza amafutha atshizwe ngaphandle komzimba wesitofu mancinci. Oko kukuthi, i-atomization ihluphekile (4) I-injector yamafutha ayivalwanga ngokuqinileyo. Xa isitofu samafutha sisebenza, ivalve yenaliti kunye nesihlalo sevalve iya kungcangcazela, nto leyo eya kubangela ukuqhekeka kokudinwa kwindawo yokusebenza yevalve yenaliti kunye ne-delamination deformation. Ukongeza, kukho ukungcola komatshini, ukhukuliseko lokuhamba kwehydraulic kunye nokuCorrosion kunye nezinye iimpembelelo ezinciphisa uburhabaxa bomsebenzi wevalve yenaliti kunye nesitulo sevalvu, kwaye ukusebenza kokutywina kuba mbi kwaye ukuvuza kweoyile, okuchaphazela ukonyuka koxinzelelo lwamafutha ngaphakathi. igumbi le-oyile ye-annular kunye nokungakwazi ukunyusa ubuninzi beeathomu ze-fuel, okubangela ukuba i-atomization ihlupheke.
