Whakataki hua
Tono matua
1.Ki te whiwhi i te tere o te purenga o te hau rewharewha me te whakaiti i nga waahanga o te (CO) waro monoxide, (HC) hydrocarbons me (NOx) hauota waikura i roto i te hau whakamomori, me whakamahi nga waka EFI e toru-ara nga huringa catalytic. Engari, kia pai ai te whakamahi i te kaitahuri catalytic e toru-ara, he mea tika ki te whakahaere tika i te tauwehenga hau-wahie kia tata tonu ki te tauwehenga hau-wahie. I te nuinga o te wa ka whakauruhia te whakakorikori i waenga i te manifold me te muffler. He āhuatanga te pūoko hāora ka huri ohorere tana ngaohiko whakaputa tata ki te ōwehenga hau-wahie (14.7: 1). Ka whakamahia tenei ahuatanga ki te kite i te kukū o te hāora i roto i te hau whakapau ka whakahokia ki te rorohiko hei whakahaere i te ōwehenga hau me te wahie. A, no te nui ake te ōwehenga hau-wahie tūturu, ka piki ake te kukū o te hāora i roto i te hau whakapau ka whakamohio te pūoko hāora ki te ECU o te ahua kikokore o te ranunga (te kaha hikohiko iti: O volts). A, no te he iti iho te ōwehenga rangi-wahie i te ōwehenga rangi-wahie ariā, te kukū o te hāora i roto i te hau pau, me te āhua o te pūoko hāora (te kaha electromotive nui: 1 volt) ka whakamōhiotia ki te rorohiko ECU.
Ka whakatauhia e 2.ECU mehemea he iti, he teitei ranei te tauwehenga hau-wahie i runga i te rereketanga o te kaha hikohiko mai i te puoro hāora, me te whakahaere i te roanga o te werohanga wahie. Heoi, ki te he te kaiwhakawhiti hāora, me te mea he rereke te kaha o te hikohiko whakaputa, kaore e taea e te rorohiko ECU te whakahaere tika i te tauwehenga hau-wahie. Na reira, ka taea hoki e te kaitao hāora te hanga i te hapa o te tauwehenga hau-wahie na te kakahu o nga miihini me etahi atu waahanga o te punaha EFI. Ka taea te kii koinei anake te puoro "maramarama" i roto i te punaha EFI.
3.Ko te mahi a te pukoro ko te whakatau mehemea he nui atu te hāora i roto i te hau paura o te miihini i muri i te wera, ara, ko te ihirangi hāora, me te huri i te ihirangi hāora ki te tohu ngaohiko me te tuku ki te rorohiko miihini, na reira ka taea e te miihini te mohio ki te whakahaere kati-koropiko me te nui o te hau hei whainga; Me whakarite ko te kaitahuri catalytic e toru-ara te tino pai o te hurihanga mo te waiwaro (HC), te waro monoxide (CO) me te hauota waikura (NOX) i roto i te hau pau, me te huri me te purea i nga parahanga kua tukuna ki te nui rawa atu.
Te whakataki whakamahinga
He nui te whakamahi i nga hiko o te hau i roto i te hinu, te ahumahi matū, te waro, te whakarewa, te hanga pepa, te tiaki ahi, te whakahaere a te taone, te rongoa, te motuka, te aro turuki i te hau me etahi atu ahumahi.
