Isebenza kanjani imitha yesisindo somoya futhi kungani kufanele uyinakekele?
Okuqukethwe
Ihlelwa kanjani imitha yokugeleza komoya futhi yini ephuka kuyo?
Ucabangani - siyini isilinganiso sengxube kaphethiloli nomoya? Kulelo nalinye ilitha likaphethiloli, kuno-14,7 kg womoya, onikeza ngaphezu kwamalitha ayi-12 XNUMX. Ngakho-ke umehluko mkhulu, okusho ukuthi kunzima ukulawula injini ukuze ibe nokubunjwa okuyikho kwengxube enikezwa endaweni yenjini. Yonke le nqubo ilawulwa yi-processor equkethwe kulokho okubizwa ngokuthi injini ye-ECU. Ngokusekelwe kumasiginali atholwe kuzinzwa, yenza i-injection metering, i-throttle opening nezinye izenzo eziningi ezithinta ukusebenza kwenjini yomlilo yangaphakathi.
Izinhlobo zamamitha okugeleza ezinjinini ezivuthayo zangaphakathi
Ngokuhamba kweminyaka, lezi zisetshenziswa ziye zanemba futhi zithembekile. Okwamanje kunezinhlobo ezi-3 zama-flowmeters asetshenziswayo:
● i-valve;
● okukhulu;
● i-ultrasonic.
Ihlelwa kanjani i-petal flow meter?
Imitha yokugeleza komoya enjalo yayisetshenziswa emiklamo emidala. Iqukethe ama-dampers (yingakho igama) exhunywe kunzwa yomoya kanye ne-potentiometer. Ngaphansi kwethonya lokuphambuka kwe-shutter, ecindezelwa ngokumelene nokumelana komoya, i-voltage ye-potentiometer iyashintsha. Umoya omningi ofinyelela ku-multifolded, i-voltage yehla futhi ngokuphambene nalokho. I-damper meter nayo ine-bypass evumela injini ukuthi ingenzi lutho uma i-damper ivimbela ukungena komoya.
Iyini imitha ye-air mass futhi isebenza kanjani?
Lona umklamo ofakwe ugesi kakhulu uma uqhathaniswa nemitha yomswakama. Iqukethe umzila okudlula kuwo umoya, ucingo olushisayo kanye neyunithi yokufudumeza. Yiqiniso, idivayisi ihlanganisa nokulawula izinto zikagesi nezinzwa ezithumela isignali kukhompuyutha. Imitha yokugeleza komoya yezimoto ikala ukugeleza komoya okukhulu. Lokhu kwenziwa kusetshenziswa ucingo lweplatinamu, olugcinwa ekushiseni okungaguquki okungaba ngu-120-130°C. Ngenxa yomklamo olula kanye nokusebenza kahle okuphezulu, ama-flowmeters alolu hlobo awakhawuleli amandla amadivaysi omlilo futhi awadali ukumelana komoya.
Ultrasonic flow meter emotweni
Lolu uhlelo lokulinganisa ukugeleza komoya oluyinkimbinkimbi kakhulu. Inhliziyo yale divayisi iwumshini wokudlidliza obangela ukunyakaza komoya okunezimo ezihlukahlukene kuye ngenani lomoya. Ukudlidliza kuthathwa umbhobho, obese udlulisela isignali ku-transducer eyenza izibalo. Imitha yokugeleza komoya enjalo iyona enembe kakhulu, kodwa ukuze uthole imiphumela ethile, kudingeka uhlelo olubanzi lokulinganisa nokuhlaziywa kwemiphumela.
Imitha ye-air mass - kungani iphuka?
Usuvele uyazi ukuthi i-flow meter iyini nokuthi isebenza kanjani, kodwa kungani ihluleka? Okokuqala, izinhlobo ze-damper azimelani kakhulu nokusebenza okungalungile kokufakwa kwegesi. I-damper ku-flowmeter ivala ngokushesha ngaphansi kwesenzo se-backfire futhi yonakaliswe.
Ukunukubezeka komoya kuyinkinga evame kakhulu kumishini eyinqwaba. Ngakho-ke, inkinga ihlotshaniswa nesimo sengqondo sokunganaki ekusebenzeni, isibonelo, ukuntuleka kokushintshwa okujwayelekile kwesihlungi somoya. Umphumela ungase futhi ube isihlungi sezemidlalo esiyikhonikhi esinikeza ukuhudula okuncane nokusebenza okungcono, kodwa uma sisetshenziswa ngokungalungile, asibambi ukungcola okuningi njengesihlungi sephepha esinabile.
Imitha ye-air mass - izimpawu zomonakalo
Inkinga yemitha yesisindo somoya elula ukuyixilonga ukulahlekelwa amandla enjini. Amanani okugeleza komoya okungalungile adluliselwa kusilawuli senjini, esikhiqiza umthamo kaphethiloli olungiswa yisiginali, hhayi inani langempela lamagesi afakwe egumbini elivuthayo. Ngakho-ke, imoto ingase ingabi namandla, isibonelo, ebangeni eliphansi lejubane lenjini.
Ungahlola kanjani ukuthi imitha ye-air mass yonakele?
Indlela yokuhlola imitha yokugeleza emotweni? Indlela elula ukuxhuma imoto kusixhumi esibonakalayo sokuxilonga noma ukuthola imoto efanayo phakathi kwabangane bese uhlela kabusha imitha yokugeleza ukusuka kwelinye ukuya kwelinye. Ukuhlanza imitha yokugeleza kuyanconywa futhi ngokunyuka kwesidingo sikaphethiloli kanye nokwakheka okungalungile kwegesi yokukhipha umoya.
Indlela yokuhlanza imitha yokugeleza emotweni?
Ungasebenzisi amanzi kulokhu! Kungcono ukusebenzisa amalungiselelo okufutha futhi uhlanze imitha yokugeleza yemoto ngawo. Linda ukuthi umuthi uhwamuke ngokuphelele. Uma ukungcola okuningi kuye kwanqwabelana kuwo, hlola futhi umzimba we-throttle futhi uwuhlanze uma kunesidingo.
Amasistimu okulinganisa ukugeleza komoya angasiza kakhulu ukusebenza kwenjini evuthayo yangaphakathi. Ukusebenza okulungile kwemitha yokugeleza kubaluleke kakhulu, ngoba uma kunezinkinga ngalesi sici, kuzoba nokwehla kokusebenza kwenjini. Ukuqapha isimo sayo nokuhlanza kuyimisebenzi okufanele yenziwe lapho kuvela izimpawu ezishaqisayo.
