Oxygen haska: da na'urar da saduwa

Na'urar haska lambda bincike (ko in ba haka ba masu motoci kalmomi, da lambda bincike) - a inji cewa shi ne alhakin da taro da kuma rabo na man fetur da kuma iska a cikin man fetur-iska cakuda a lokacin da shirye-shiryen da kuma ciyar da ta man fetur tashoshi a cikin engine Silinda. A kan tushe na shaidar na'urar dogara a kan man fetur total amfani, ikon da muhimmancin da mota. A gaskiya, da muhimmancin da Na'urar haska ne m tare da carburetor da injector, tun biyu ana kai tsaye da hannu a cikin shirye-shiryen da na man fetur cakuda. A yau labarin da muka koya cewa irin wannan lambda bincike, yadda yake aiki da kuma abin da ake nufi.

na'urar

Akai (yafi aiki memba), da haska ne porous yumbu abu wanda aka samar zirconium dioxide. The sosai guda zane na wannan na'urar ya shafi wadannan sassa:

• karfe casing.
• waya cuff.
• yumbu insulator.
• tuntube dumama kewaye.
• wayoyi.
• O-zobe.
• Zirconia yumbu tip.
• sanda da wani karkace filament.
• ciki garkuwa da wani musamman rami domin shaye gas.
• da matsanancin garkuwa da wani bude ga yanayi iska.
• tara sakonni.

Ina shi located?

Sau da yawa lambda bincike (VAZ-2110 ciki har da) dake a cikin shaye tsarin, a waje na shaye da yawa. Har ila yau, ka sani cewa wasu motocin iya zama biyu irin wannan na'urorin. Daya daga cikinsu na iya zubar cirewa daga mai kara kuzari, da kuma na biyu - bayan shi. Aiki na biyu lambda bincike muhimmanci ƙara dafa abinci yadda ya dace da kuma daidaito na man fetur-iska cakuda kara zuwa ta samar da ciki konewa engine konewa jam'iyya.

manufa na aiki

A algorithm na wannan na'urar dogara ne a kan kaddarorin da zirconium oxide. Saboda haka, an sarrafa at zazzabi na akalla 350 digiri Celsius. A wasu lokuta, domin hanzarta dumama tsari, amfani da musamman hita. A dukan manufa na lambda bincike za a iya raba da dama, saukarwa:

1. Ciyar shaye gas wuce ta hanyar kara kuzari da kuma shaye bututu. Duk da haka, da suka gudãna daga ƙarƙashinsu a kusa da aiki surface na haska lambda bincike wanda aka located cirewa daga mai kara kuzari.
2. Bugu da ari, wannan na'urar nazarin matakin O2 a shaye gas da kuma kwantanta da data tare da matakin a cikin yanayi.
3. Lokacin aiki na haska samar da wani m bambanci, sa'ilin da dabarar da aka aika wani gajeren sakonni ga engine ECU.
4. Bayan nan, cikin kwamfuta tafiyar matakai da bayanai da kuma kai da siginar zuwa wani takamaiman adadin na'urorin, game da shi, daidaitawa da aiki na actuators.

Ya kamata a lura da cewa a cikin hali na karancin oxygen a cikin tsarin, wato, da iska-man fetur cakuda, konewa kayayyakin ba su cikakken oxidized. A irin wannan yanayin, da abin hawa ya fara rasa ta lokacinta da kuma karuwa a fetur amfani auku (ramammu cakuda kafa a cikin masallãci). Idan iska a cikin tsarin da yawa, wannan take kaiwa zuwa wani bai cika bazuwar na nitric oxide, wanda shi ne ma ba da hanya mafi kyau da aka nuna a kan aiki na engine.
