I-Diesel Injector Fuel Injector 0445110484 Bosch ye-Deutz

Izijovo zikagesi ziyizingxenye zikagesi ezincane ezisetshenziselwa ukuletha uphethiloli ngesifutho ngqo endaweni eningi ewuthathayo phambi kwevalvu yokudonsa enjinini yedizili. Ama-injection ka-diesel fuel ayinkimbinkimbi; i-injector inesihlungi se-micron esiphezulu ohlangothini lwe-inlet oluphezulu oluhambisana nezimbobo ezincane ezinosayizi we-hypodermic phansi ukuze kusetshenziswe i-athomu kaphethiloli wedizili. Isibaseli sikadizili sisebenza njengomthombo wokugcoba wezingxenye zangaphakathi zomjovo. Umthombo oyinhloko wokwehluleka kwama-injection amanzi kuphethiloli. Lapho amanzi kuphethiloli esusa izici zokugcoba izingxenye zangaphakathi ziguga ngokushesha futhi i-injector iyonke ingahluleka ngokushesha.

Ama-injection ayingxenye yenjini ebaluleke kakhulu. I-valve yokujova ivula futhi ivale nge-rpm efanayo nenjini ye-diesel. I-RPM ejwayelekile yezinjini zikadizili eNyakatho Melika icishe ibe ngu-1800. Lokhu kulingana cishe nezikhathi eziyi-140,000 ngehora! Ngokungeziwe emanzini kuphethiloli, ama-injection angaphansi kwe-carbon kanye nezinhlayiya zokungcola ezethulwa kuyunithi kusetshenziswa into embi yokuhlanza umoya. Uhlobo lukaphethiloli, ibanga nezithasiselo ezisetshenzisiwe nazo zinomthelela omkhulu esikhathini esilindelekile sokuphila komjovo kaphethiloli. I-ECM (Engine Control Module) ilawula ama-injector kaphethiloli ezinjinini eziningi zikadizili zikagesi. Ama-injection kadizili ahlala enamandla uma ukhiye uvuliwe noma ngabe injini ivuliwe. I-ECM igxilisa umjovo, igcwalise isekethe futhi ibangele ukuthi umlomo womjovo uvuleke. I-ECM ngemva kokuthola ulwazi oluvela kuzinzwa zokulawula ezihlukahlukene inquma ubude besikhathi ama-injection okudingeka abekwe phansi ukuze ajove inani eliqondile likaphethiloli uma kubhekwa isidingo sokukhipha amandla enjini.

Inqubo yokuvula, ukuvala kanye nokukhipha ama-injection kadizili inani elifanele likaphethiloli kwenzeka ngama-millisecond. Ukudubula komjikelezo womjovo ngokwesilinganiso kuqedwa kuma-milliseconds angu-1.5 kuya kwangu-5. Ama-injection kaphethiloli kadizili ahlukene ngomumo nosayizi kuye ngokuthi injini yenziwe kanjani nemodeli kanjalo nesidingo samandla. Ama-injection ezimoto mancane kakhulu kunezinhlelo zedizili ezisindayo futhi akalwa ngamayintshi ayi-cubic. Kunezinhlobo ezimbili zama-injection ka-diesel fuel: eyokuqala ibizwa ngokuthi umjovo womzimba we-throttle lapho ama-injection angu-1-2 atholakala ku-throttle body ngokwayo enjinini ye-diesel futhi anikeze inani elilinganisiwe le-mist fuel spray endaweni eningi. Lolu hlelo lokulethwa lukhokhisa inkatho futhi i-valve yokudonsa idonsa uphethiloli kusilinda senjini. Isistimu yokulethwa kwesibili, eyaziwa ngokuthi i-port ngayinye yohlobo lwe-fuel injector, yintsha futhi iyonga kakhulu kuphethiloli. Uhlobo lomjovo wembobo lusebenza kahle kakhulu kune-carburetor njengoba lulungisa ukuminyana komoya nokuphakama futhi aluncikile ku-vacuum ehlukahlukene.

Ngokungasebenzi kahle komjovo we-throttle spray kufika lapho amasilinda aseduze kakhulu nama-injection enengxube engcono kunalawo akude kakhulu. Ngohlobo lomjovo wechweba leli phutha liqedwa ngokujova inani elifanayo likaphethiloli kusilinda ngasinye enjinini.
