Izinzwa zezimoto zingamathuluzi okokufaka wesistimu yekhompyutha yezimoto.Badlulisela ulwazi lwezimo ezihlukahlukene zokusebenza ngesikhathi sokusebenza kwemoto njengejubane lemoto, izinga lokushisa lemidiya ehlukahlukene, isimo sokusebenza kwenjini kusignali kagesi ukuze ithunyelwe kumakhompyutha ukugcina injini isesimweni esihle sokusebenza.
Njengoba izimoto ziya ngokuya zihlakanipha, i-transformer imisebenzi eminingi emotweni isetshenziswa amakhompyutha.Kunezinzwa eziningi emotweni eyodwa, zingahlukaniswa zibe inzwa ye-oxygen, inzwa yokugeleza komoya, inzwa yejubane, inzwa ye-nitrogen oxide, inzwa yokushisa kanye nenzwa yokucindezela ngokusho komsebenzi wayo.Uma enye yezinzwa yehlulekile, idivayisi ehambisanayo ngeke isebenze noma isebenze ngendlela engavamile.Bese, ake sethule ezinye izinzwa eziyinhloko kanye nomsebenzi wazo.
Inzwa yokugeleza
Inzwa yokugeleza isetshenziselwa ukukala ukugeleza komoya wenjini nokugeleza kukaphethiloli.Isilinganiso sokugeleza komoya sisetshenziswa isistimu yethrekhi kagesi yokulawula injini ukuze kunqunywe izimo zokuvutha, ukulawula isilinganiso sephethiloli yomoya, ukuqala, ukuthungela, njll. Kunezinhlobo ezine zezinzwa zokugeleza komoya: i-rotary vane (uhlobo lweblade), uhlobo lwe-carmen vortex. , uhlobo lwezintambo ezishisayo kanye nohlobo lwefilimu eshisayo.Isakhiwo se-flowmeter yomoya yohlobo lwe-rotary vane silula futhi ukunemba kokulinganisa kuphansi.Ukugeleza komoya okukaliwe kudinga isinxephezelo sezinga lokushisa.I-Carmen vortex yohlobo lwe-air flowmeter ayinazo izingxenye ezihambayo, ezinokubonisa okubucayi nokunemba okuphezulu.Idinga futhi isinxephezelo sethemomitha yezinga lokushisa.
I-hot wire air flowmeter inokunemba okuphezulu kokulinganisa futhi ayidingi isinxephezelo sezinga lokushisa, kodwa kulula ukuthintwa ukushaywa kwegesi nokuphuka kwentambo.Isimiso sokulinganisa se-hot film air flowmeter siyafana nesocingo olushisayo lwe-air flowmeter, kodwa ivolumu incane, ifanele ukukhiqizwa ngobuningi kanye nezindleko eziphansi.Sonke siyazi ukuthi kukhona ukushaja i-USB ezimotweni eziningi, singashaja ifoni yethu ngeshaja ephathwayo engenantambo.
Umsebenzi wenzwa yokugeleza
Ijubane le-impeller lilingana nokugeleza, futhi inani lokuguquguquka kwe-impeller lilingana nokugeleza okuphelele.Okukhiphayo kwe-flowmeter ye-turbine isignali eshintshiwe yefrikhwensi, engathuthukisi nje kuphela ukuthikamezeka kwesekethe yokuthola, kodwa futhi yenza kube lula isistimu yokuthola ukugeleza.Isilinganiso sobubanzi bayo singafinyelela ku-10:1 futhi ukunemba kwayo kungaphakathi kuka-± 0.2%.Isikhathi esingaguquki se-turbine flowmeter ene-inertia encane nosayizi omncane singafinyelela imizuzwana engu-0.01.
Inzwa yokucindezela
Inzwa yokucindezela isetshenziswa kakhulu ukuthola ingcindezi engalungile yesilinda, ingcindezi yasemkhathini, i-boost ratio yenjini ye-turbine, i-cylinder pressure yangaphakathi, ingcindezi kawoyela, njll.Izinzwa zengcindezi yezimoto zisetshenziswa kabanzi ku-capacitive, piezoresistive, differential transformer (LVDT) kanye ne-surface elastic wave (SAW).
Imisebenzi yenzwa yokucindezela
Inzwa yokucindezela ivamise ukwakhiwa ngento ezwela ukucindezela kanye neyunithi yokucubungula isignali yenethiwekhi yokubona.Ngokusho kwezinhlobo ezahlukene zengcindezi yokuhlola, izinzwa zokucindezela zingahlukaniswa zibe inzwa yokucindezela kwe-gauge, inzwa yokucindezela okuhlukile kanye nenzwa yokucindezela okuphelele.Inzwa yokucindezela iyinzwa evame ukusetshenziswa kakhulu ekusebenzeni kwezimboni.Isetshenziswa kabanzi ezindaweni ezahlukahlukene zokulawula okuzenzakalelayo ezimbonini, okubandakanya ukongiwa kwamanzi kanye namandla kagesi, ezokuthutha zikaloliwe, isakhiwo esihlakaniphile, ukukhiqiza ukulawula okuzenzakalelayo, indiza, imboni yezempi, i-petrochemical, umthombo kawoyela, amandla kagesi, umkhumbi, ithuluzi lomshini, ipayipi nezinye izimboni eziningi.
Inzwa yokungqongqoza
Inzwa ye-Knock isetshenziselwa ukubona ukudlidliza kwenjini, ukulawula nokugwema ukungqongqoza kwenjini ngokulungisa i-engeli yokuthungela kusengaphambili.I-Knock ingatholwa ngokuthola umfutho we-cylinder, ukudlidliza kwe-injini nomsindo wokusha.Izinzwa ze-Knock ziyi-magnetostrictive ne-piezoelectric.Izinga lokushisa lesevisi yenzwa yokugoqa kazibuthe ngu-40 ℃ ~ 125 ℃, futhi ububanzi befrikhwensi ngu-5 ~ 10kHz;Enkabeni yefrikhwensi engu-5.417khz, ukuzwela kwenzwa yokugoqa kwe-piezoelectric kungafinyelela ku-200mV / g, futhi inomugqa omuhle kububanzi be-amplitude obungu-0.1g ~ 10g.
Umsebenzi we-knock sensor
Isetshenziselwa ukukala i-jitter yenjini futhi ulungise i-engeli yokushisa ngaphambi kwesikhathi lapho injini ikhiqiza i-knock.Ngokuvamile, ziyi-ceramics ye-piezoelectric.Lapho injini inyakaza, izitsha zobumba ngaphakathi ziyampintshana ukuze zikhiqize isignali kagesi.Ngenxa yokuthi isignali kagesi ibuthakathaka kakhulu, intambo yokuxhuma yezinzwa ezijwayelekile zokugoqa isongwe ngocingo oluvikelwe.
Ngokufigqiwe
Izimoto zanamuhla zisebenzisa izinzwa eziningi ezihlukene, futhi inzwa ngayinye inezinjongo eziwusizo.Imoto yesikhathi esizayo cishe izoba nezinzwa ezingamakhulu ambalwa ezidlulisela ulwazi kuma-ECU anamandla futhi yenze izimoto zisebenze kahle kakhulu futhi ziphephe kangcono ukushayela.Izinzwa zethu zikhethekile ezinhlotsheni ezahlukene zezimoto, njengathi esinazoI-VW Oxygen Sensor.Izinzwa zibaluleke kakhulu emotweni.Ukuze uthole ulwazi olwengeziwe mayelana nezinzwa ezizenzakalelayo, pls vula ku-YASEN.
