1.E le hore u fumane tekanyo e phahameng ea ho hloekisa khase le ho fokotsa likarolo tsa (CO) carbon monoxide, (HC) hydrocarbons le (NOx) nitrogen oxides ka khase ea ho qeta, likoloi tsa EFI li tlameha ho sebelisa li-converter tse tharo tsa catalytic. Leha ho le joalo, e le hore u sebelise ka katleho mochine oa motlakase oa litsela tse tharo, ho hlokahala hore u laole ka mokhoa o nepahetseng tekanyo ea mafura a moea e le hore e lule e le haufi le karo-karolelano ea moea le mafura a moea. Hangata, "catalyst" e kenngoa pakeng tsa "exhaust manifold" le "muffler". Sensor ea oksijene e na le tšobotsi ea hore motlakase oa eona o tsoang ka tšohanyetso o fetoha haufi le karo-karolelano ea mafura a moea (14.7: 1). Tšobotsi ena e sebelisetsoa ho bona hore na oksijene e teng ka har'a khase ea mouoane ebe e e khutlisetsa khomphuteng ho laola tekanyo ea mafura a moea. Ha tekanyo ea sebele ea mafura a moea e e-ba holimo, khatello ea oksijene ka khase ea ho qeta e eketseha 'me mochine oa oksijene o tsebisa ECU ka boemo bo fokolang ba motsoako (matla a manyenyane a electromotive: O volts). Ha karo-karolelano ea mafura a moea a le tlase ho feta tekano ea moea le mafura a moea, khatello ea oksijene ka khase ea ho qeta e fokotseha, 'me boemo ba sensor ea oksijene (matla a maholo a electromotive: 1 volt) e tsebisoa k'homphieutha ea ECU.

2.ECU e ahlola hore na karo-karolelano ea mafura a moea a tlase kapa a phahame ho latela phapang ea matla a electromotive ho tloha ho sensor ea oksijene, 'me e laola nako ea ente ea mafura ka tsela e nepahetseng. Leha ho le joalo, haeba transmitter ea oksijene e fosahetse 'me matla a electromotive a hlahisoang a sa tloaeleha, k'homphieutha ea ECU e sitoa ho laola ka nepo karolelano ea mafura a moea. Ka hona, sensor ea oksijene e ka boela ea etsa phoso ea karolelano ea mafura a moea e bakoang ke ho roala ha mechine le likarolo tse ling tsa tsamaiso ea EFI. Ho ka boleloa hore ke eona feela sensor e "bohlale" tsamaisong ea EFI.

3. Mosebetsi oa sensor ke ho fumana hore na ho na le oksijene e feteletseng ka har'a khase ea enjene ka mor'a ho tuka, ke hore, litaba tsa oksijene, le ho fetola litaba tsa oksijene hore e be lets'oao la motlakase ebe o li fetisetsa k'homphieutheng ea enjene. hore enjene e ka fumana taolo e koetsoeng e nang le moea o feteletseng e le sepheo; Netefatsa hore sesebelisoa sa mekhoa e meraro se nang le matla a ho fetola li-hydrocarbon (HC), carbon monoxide (CO) le nitrogen oxides (NOX) ka har'a khase e tsoang, 'me se fetola le ho hloekisa litšila tse lahliloeng ka mokhoa o fetisisang.

Li-sensor tsa oksijene li sebelisoa haholo ho petroleum, indasteri ea lik'hemik'hale, mashala, metallurgy, ho etsa pampiri, ts'ireletso ea mollo, tsamaiso ea masepala, meriana, koloi, leihlo la khase ea khase le liindasteri tse ling.
