Ziyini izinzwa zezimoto?
Izinzwa zemoto noma izinzwa zemoto ziyizinto zikagesi ezilandelela izici ezihlukene zemoto. Bangakwazi ukuqapha izinga lokushisa lemoto, umfutho, nesivinini, futhi bazise umshayeli ukuba enze izinguquko ezifanele. Bangakwazi futhi ukuthumela ulwazi ngokuzenzakalelayo kuyunithi yokulawula kagesi (ECU) ukuze benze izinguquko ezidingekayo.
Kunezinhlobo eziningi zezinzwa zemoto eziklanyelwe imisebenzi ehlukene. Zifakwe ezingxenyeni ezihlukene zemoto, okuhlanganisa injini, ithangi likaphethiloli, i-exhaust manifold, kanye negumbi lomlilo.
Amathrendi emakethe yezinzwa zezimoto zomhlaba wonke
The imakethe yezinzwa zezimoto emhlabeni jikelele ilinganiselwa ku-US $ 10.10 billion ngo-2021 futhi izofinyelela uphawu lwe-US $ 15.6 billion ngo-2028. Kulindeleke ukuthi ikhule ngezinga lokukhula elihlanganisiwe lonyaka (CAGR) lika-6.38%.
Ukukhula kwemakethe okusheshayo kuvela ezinzuzweni zezinzwa. Basiza abashayeli ukuthi baqaphe ukuthi izimoto zidla kangakanani uphethiloli, isivinini sazo kanye nesikhathi sokulungisa izingxenye zezimoto ezahlukene. Ngaphezu kwalokho, baxwayisa abashayeli ngengozi ezayo ngokubona izithiyo nokushintsha kwesimo sezulu.
Imakethe yomhlaba wonke yezinzwa zezimoto kulindeleke ukuthi ikhule ngo-2023 nangale kwalokho njengoba abashayeli bemukela izimoto ezidijithali ukuze zishayele kalula futhi ziphephile. Ngaphandle kwalokho, izinzwa zibalulekile ekunqandeni izingozi zomgwaqo ngokuthumela izixwayiso kubashayeli.
Imisebenzi yezinzwa zezimoto
Umsebenzi oyinhloko wezinzwa zemoto ukuthola izinguquko ekusebenzeni nezimo zemoto nokuthumela ulwazi ku-ECU. Iyunithi yokulawula ye-elekthronikhi ingenza ukulungiswa okudingekayo noma ithumele isixwayiso kumshayeli ukuze enze izinguquko ezifanele.
Eminye imisebenzi yezinzwa ezahlukene ihlanganisa:
- Ukuqapha izici ezihlukahlukene zemoto njengezinga lokushisa, inani le-oxygen, nesivinini
- Ukuthumela ulwazi ku-ECU ukuze yenze izinguquko ezifanele ngokuzenzakalelayo noma ukuxwayisa umshayeli
- Ukwazisa umshayeli ukuthi uzoyilungisa nini imoto
- Ukubona ukuba khona kwamagesi ayingozi njenge-nitrogen dioxide ku-exhaust futhi uxwayise umshayeli ukuthi athathe izinyathelo zokuphepha
- Ukuqinisekisa ukuthi ingxube kaphethiloli ethangini ivutha ngendlela efanele ukugwema ukumoshakala
Izinhlobo zezinzwa zezimoto
Ziningi izinhlobo zezimoto izinzwa emakethe namuhla. Zenzelwe imisebenzi ehlukene, kusukela ekuqapheni ukusetshenziswa kukaphethiloli isimo somoya kanye nesivinini semoto. Zihlanganisa okulandelayo:
Inzwa yokugeleza komoya
Ukugeleza komoya inzwa iqapha ukuminyana komoya endaweni evuthayo yenjini. Lokhu kuyisiza ukuthi igcine isilinganiso esifanele sengxube ye-air-fuel ukuze ikhiqize amandla amaningi. Amanani aphansi omoya-mpilo aholela ekushiseni okungaphelele kukaphethiloli, okubangela ukungcola.
Le nzwa isiza ukunciphisa ukumosheka kukaphethiloli nokunqanda ukwehluleka kwenjini.
Inzwa yokushaya injini
Inzwa yokushaya injini ibekwe endaweni evuthayo yenjini. Ithola ukuthuthwa kukaphethiloli okungalungile, okungase kubangele ukungqongqoza futhi kuphazamise ukusebenza kahle kwenjini.
Lapho ingxube ye-fuel air ivutha ngaphambi kokuba ipulaki iqhume, i- injini yokushaya inzwa ixwayisa umshayeli ukuthi enze ukulungisa okufanele.
Inzwa yesivinini senjini
Le divayisi ilandelela isivinini senjini ngokuqapha indawo kanye nesivinini se-crankshaft. Ifakwe ku-shaft, ibona indawo yayo bese idlulisela imininingwane ku-ECU, enquma isikhathi sokujova uphethiloli.
Lokhu kusiza i-ECU ukuthi yenze i-spark plug isebenze ngesikhathi ukuze ikhiqize inhlansi yokuthungela kukaphethiloli.
Inzwa yendawo ye-Camshaft
Le divayisi iqapha isikhundla nesivinini se-camshaft. Ithola ukuvulwa nokuvalwa kwamavalvu e-camshaft nezinzwa lapho isondela endaweni ephezulu efile (TDC). I-camshaft position sensor isebenza nenzwa yenjini ukuqinisekisa ukuthuthwa kukaphethiloli okulungile.
Inzwa ye-Manifold absolute absolute (MAP).
The Inzwa ye-MAP iqapha ukucindezela okuningana kwemoto futhi idlulisele ulwazi kukhompuyutha yenjini. Lokhu kuqinisekisa isilinganiso esifanele se-air-fuel sokukhiqiza amandla afanele. Yazisa futhi i-ECU ngokumoshwa kukaphethiloli.
Isivinini inzwa
The inzwa yesivinini semoto (VSS) iqapha isivinini sesondo. Ithumela ulwazi kuyunithi yokulawula injini, elungisa isilinganiso sikaphethiloli womoya kanye nesikhathi sokuthungela ukuze ilawule isivinini.
Inzwa ye-voltage
The inzwa ye-voltage ilawula isivinini sesondo futhi iqinisekisa ukuthi liyakhuphuka noma lehliswa ngendlela efanele. Lapho isivinini semoto sifinyelela ubukhulu baso, inzwa idlulisela ulwazi kuyunithi ye-elekthronikhi ukuze imise imoto, ukuze igweme ukulimala kwenjini.
Inzwa ye-oxygen
The inzwa ye-oksijini ilandelela amazinga komoyampilo enjinini yakho. Njengoba iseduze ne-exhaust eningi, iqhathanisa izinga le-oxygen enjinini nangaphandle ukuze kuqinisekiswe ukuthi kunokwanele ukusebenzisa uphethiloli ngendlela efanele.
Inzwa yokuma kwe-Throttle
The inzwa isikhundla mpintsha (I-TPS) itholakala ku-butterfly shaft futhi iqapha ukuthi injini ingenisa umoya kanjani. Ikala izinga lapho i-throttle valve ivuleka noma ivaliwe ngayo ukuze kulinganiswe inani lokungenisa umoya. Okunye ukusunduzela phansi kwe-pedal kusho ukudonsa komoya okuphezulu, futhi inzwa ikhombisa i-ECU ngokufanele.
Inzwa yokushisa
Uyaziwa nangokuthi inzwa yokushisa epholisayo, le divayisi iqapha izinga lokushisa kwenjini. Uma ukufundwa kuphezulu, iwathumela eyunithi yokulawula injini, elungisa ukuvutha kukaphethiloli ukuze kulawuleke izinga lokushisa.
Inzwa yemvula
A inzwa yemvula yemoto ithola imvula bese idlulisela umlayezo ohlelweni lokulawula ngogesi. I-ECU ithumela okokwesula i-windscreen ukuvimbela ukungena kwamanzi emvula phakathi nemoto. Iphinde ithuthukise ukubonakala ngokugcina i-windscreen icacile.
Izinzuzo kanye nokubi kwezinzwa zemoto
Izinzwa zezimoto zisiza abashayeli ukuthi bagibele ngokuphepha futhi zibaxwayise ngengozi ezayo. Nazi ezinye izinzuzo kanye nebubi izinzwa imoto.
Izinzuzo
- Basiza abashayeli ukuthi babone izingxenye ezilimele
- Basiza ukugcina injini
- Ukulawula imoto okuzenzakalelayo kwenza ukushayela kube lula
- Bathumela izexwayiso kubashayeli futhi basize ukugwema izingozi
- I-ECU yenza izinguquko ezifanele ngesikhathi ukuze kuncishiswe ukulimala kwezimoto nokumoshakala kukaphethiloli
Okumbi
- Izinzwa ezinephutha ziholela ekulimaleni kwenjini
- Kuyabiza ukuzifaka nokuyinakekela
- Izinzwa zekhwalithi ephansi zidinga ukushintshwa njalo okumba eqolo
- Babona kuphela izithiyo ngaphambili noma ngemuva kwemoto kodwa bayehluleka ukubona ezisemaceleni
Imibuzo ejwayelekile ukubuzwa
Iyini inzwa yemoto?
