Indlela yokuhlola i-lambda probe

Uma unesithakazelo kumbuzo wokuthi ungabheka kanjani i-lambda probe, usufike endaweni efanele. Ukuze wenze lokhu kuhlolwa, uzodinga izinto ezilandelayo: incwadi yokufundisa yomkhiqizi wemoto (kudingeka futhi uthole ukuthi ikuphi), i-oscilloscope, futhi ekugcineni, i-voltmeter. Uma uqoqa konke lokhu, qhubeka uvuselela injini yemoto ukushisa.

Siyazi kahle imfundo, okuyiziphi izinkomba eziyisisekelo i-lambda probe yakho. Ukuhlolwa kuhlanganisa imingcele elandelayo, ephendula ukusebenza okungalungile kwenzwa ye-oxygen. Le voltage enethiwekhi kagesi, lapha ihlanganisa nokuthuthukiswa kokushisa, kanye nokusebenza kwesistimu enesibopho sokunikeza uphethiloli. Kufanele futhi uqaphele ukufakwa kwangaphandle kwezimo ezihlukahlukene, okungukuthi, ukukhipha ukutholakala kwanoma yikuphi ukulimala komshini kubo, emzimbeni wabo noma ku-wiring.

Okulandelayo, bhekani egumbini lejini, lapho sithola khona i-llama yethu probe. Kumele kuhlolwe kusukela phezulu kuya phansi bese uqaphela izinga lokungcola kwalo. Uhlaka lwe-soot, ukuhola noma i-gray-white coating on the tip utshela inkosi ukuthi idinga ukushintshwa. Lokhu kubonisa ukusetshenziswa kwephethiloli enhle. Uma kungekho ukungcola, qhubeka endaweni elandelayo.

Uma usenesithakazelo sokuthi ungabheka kanjani i-lambda probe, yinqamule kusuka pad bese uyixhuma ngokushesha nge-voltmeter. Siqala injini futhi siphakamise ukuguqulwa kwesilinganiso sezinguquko ezinkulungwaneni ezimbili nengxenye ngomzuzu. Manje, ngosizo lwedivaysi yokucebisa, wehlisa isivinini sejinini kumaki wezinguquko eziyinkulungwane ezimbili ngomzuzu.

Uma umshini wakho unesimiso sokuthi uphethiloli olawulwa ngekhompiyutha, kufanele udonsa ithubhu ye-vacuum ngaphandle kwe- regulator control regulator yakho. Manje bheka ukufundwa kwe-voltmeter. Uma kubonisa inani eliseduze ne-0.9 Volts, khona-ke inzwa isendleleni ephelele. Uma ingabonisi lutho noma inani lingaphansi kuka-0.8 Volts - lokhu kubonisa ukungasebenzi. Kodwa umbuzo wokuthi ungahlola kanjani i-lambda probe engakaveli ngokugcwele.

Isinyathelo esilandelayo sizoba ukuhlolwa kobumpofu benhlanganisela. Sithatha ithubhu lokugcoba futhi sivusa umoya ophuza umoya. Ngomqondo omuhle we-oxygen, ukufundwa kwe-voltmeter kufanele kube ngu-0.2 Volts noma ephansi.

Manje kufanele sihlole ukusebenza kwe-lambda probe ku-dynamics. Ukuze wenze lokhu, kufanele uyixhume kwisixhumi se-feed feed. Ngemva kokwenza lokhu, xhuma i-voltmeter ngokufana nayo. Bese ukwandisa isivinini sejinini kumakhilomitha ayikhulu namashumi amabili ngomzuzu. I-voltmeter kumele kube manje yi-0.5 volts. Uma kungenjalo, inzwa ayilungile.

Lapha, ngokuyisisekelo, futhi konke ukuhlakanipha kokuhlola i-lambda probe. Ayikho ulwazi olukhethekile oludingekayo, futhi konke kungenziwa ekhaya, ngaphandle kwezinkinga. Hlola ngezikhathi ezithile le mininingwane, ngoba ikhwalithi yamafutha esiteshini samagesi awahlangabezani nezindinganiso, futhi lokhu kunomthelela ekunciphiseni okusheshayo kwemithombo ye-lambda probe hhayi nje kuphela. Uma usuthole ukuthi sesingasetshenziswa - yenza ngokushesha indawo. Inhlanhla endleleni kanye nokuhluleka okuncane.
