Kanjani inzwa-mpilo?

iziqondiso Modern kwemvelo abasakwazi esiqinile, futhi indlela yokwakheka kwezinkambiso of qeda amagesi achazwa ngokukhanyayo. Yingakho amadivayisi ekhethekile esetshenziswa umkhakha lanamuhla yezimoto. Lokhu converters okhanda amanye amathuba, okuyinto bathonywa ezingeni ezinobuthi ku qeda is kakhulu ziyancipha. Ngeshwa, amadivayisi njenge asebenza kahle kuphela ngaphansi kwezimo ezithile. Yilokho budinga nomoya-mpilo inzwa. Le mininingwane emincane efeza umsebenzi obaluleke kakhulu.

Uyini inzwa-mpilo?

Ukwakheka kahle ingxube fuel-air - lapho 1 ingxenye fuel kumele mayelana 14.7 izingxenye emoyeni. Kulokhu, lo Coefficient emoyeni ngokweqile (L) lilingana 1. ukusebenza Eyonga kulethe izotholakala kuphela uma L ilingana 1, ngephutha ka 0.01. Umsebenzi oyinhloko inzwa - ke ukulawula indlela yokwakheka ingxube uphethiloli emoyeni.

Inzwa umoya-mpilo idivaysi encane, yazalwa impahla ukungena nakwamanye amazwe. ingxenye yayo oyinhloko zirconia. Top embozwe ucezu-platinum-kuhlinzwa. idivayisi enjalo iphendula umehluko phakathi okuqukethwe oksijini emkhathini kanye negesi qeda. Ngaphezu kwalokho, edonsa ngesikhathi okukhipha efanayo umehluko ezingaba khona.

Umgomo we operation ye-probe ilula ngokwanele. Ngokunciphisa ezingeni oxygen qeda kwabangela ukusabela zirconium dioxide yokutakula. Phela, lo kulethe amatjhuguluko anjengalawa-platinum. Njengoba ukusabela ukunciphisa phezu kwelinye inzwa namachibi izinqubo, ubuqotho kanye operability we probe inakekelwa ngokuzenzakalelayo.

Kuze kube manje, kukhona onobuhle eziningana eziyisisekelo mishini. Ethandwa kakhulu kubhekwa Bosch-mpilo inzwa. Lokhu apharathasi libhekene sensitivity high futhi workability.

Two-iphuzu-mpilo inzwa

Lona omunye onobuhle eyinhloko kule divayisi. Uphenyo linanyathelisiwe a neutralizer nangasemva ke, okuyinto lusenza ulungise kahle Coefficient emoyeni ngokweqile. I electrode ngakolunye uhlangothi lwale idivayisi nabo emoyeni kuma, futhi ngakolunye - ne amagesi qeda ekuphenduleni isizukulwane umehluko ezingaba khona. Okuqukethwe oxygen ephakeme qeda, ephansi voltage elakhiwe.

Kulezo zimo lapho ezingeni oxygen ingxube uphethiloli emoyeni incipha, futhi voltage iba high, ekhiqizwa isignali kagesi, okuyinto adluliselwa uhlelo lokulawula injini.

Broadband-mpilo inzwa

Le divayisi kancane ukuhluka lowo odlule kokubili isakhiwo futhi izimiso msebenzi. It liqukethe izingxenye ezimbili Ceramic, kuba abavamile ezimbili iphuzu uphenyo futhi injected ingxenye. Phakathi ezimbili electrode ezimbili iphuzu ingxenye probe njalo voltage 450 mV elakhiwe. Ngesikhathi esifanayo, i-oksijini evela igesi qeda sidlula ingxenye akhishwa we inzwa. I ephansi ezingeni umoya-mpilo, ayanda voltage phakathi electrode amabili. Ezimweni ezinjalo, isiginali idluliselwa kuya electronic control unit. Phela, ngokuvumelana leliqhinga usebenza Vaz-mpilo inzwa.
