Izinhlobo ezahlukene zokuthungela okubi ezikhiqiza ama-burrs.

Ukuthungela okungekuhle okubangelwa umjovo ongalinganiseli wezimbobo kusezinjini zokujova ezinamaphoyinti amaningi. Ukuthungela okungekuhle okubangelwa ingxube ecebile noma engenamandla kawoyela kusilinda owodwa kubangelwa amafutha amaningi kakhulu noma amancane kakhulu ajovwe ngombhobho ngamunye (umbhobho uvalekile noma ubhajwe). Lapho isilinganiso sikaphethiloli womoya wengxube kaphethiloli womoya kusilinda esisodwa noma uphethiloli amaningana sidlula ingozi, ukuthungela okungekuhle kwenzeka lapho isilinganiso sikaphethiloli womoya sidlula i-17: 1, futhi ukuthungela okungekuhle kwenzeka lapho isilinganiso sikaphethiloli womoya singaphansi kuka-13: 1, okuholela ekushiseni okungekuhle okubangelwa umjovo kaphethiloli ongalingani osuka kumjovo kaphethiloli. Ngokuvamile, kungahlulelwa ngokungabandakanyi amathuba okuthungela okungekuhle okubangelwa isistimu yokuthungela, ukuthungela okungekuhle kwe-cylinder pressure kanye nokuvuza kwe-vacuum yesilinda esisodwa. Umjovo kaphethiloli ongalingani. I-oscilloscope yemoto ingasetshenziswa ukuqeda ukuthungela okubi okubangelwa uhlelo lokuzithungela kanye nokucindezela kwesilinda (ukuthola ukuthungela okubi okubangelwa uhlelo lokuthungela kanye nenkinga yokucindezela kwe-cylinder balance cylinder). Ukuze kuqedwe ukuvuza kwe-vacuum okuhlobene namasilinda ngamanye, i-propane (i-multifold intake, i-carburetor pad, njll.) ivamise ukungezwa endaweni noma ezungezile lapho ukuvuza kwe-vacuum kungase kwenzeke khona, futhi ngesikhathi esifanayo, njengoba kushiwo ngaphambili, i-waveform yesiginali ye-oxygen. inzwa ibonwa kusukela ku-oscilloscope ukuze kuzuzwe umgomo. Ngokuvamile, enjinini yomjovo kaphethiloli enamaphuzu amaningi, uma ukungafihli kahle okubangelwa izinhlobo A, B, no-C kungenakufakazelwa, khona-ke amathuba okungalingani okubangela imfuhlumfuhlu engathi sína ku-waveform yenzwa ye-oxygen anganqunywa. Imithetho yokwahlulela i-clutter yenzwa ye-oxygen Uma kukhona i-clutter ecacile kusignali yenzwa ye-oxygen, engavamile ohlelweni oluhluziwe, ngokuvamile izohambisana nokuhluleka okuphindaphindiwe nokuvivinywa kwenjini ngesivinini esingenzi lutho (isibonelo, ukungqongqoza kusilinda ngasinye. ukuthungela). Ngokuvamile, uma imfuhlumfuhlu ibonakala, iphutha lenjini ekugcineni lizohlotshaniswa neziqongo ezihlukahlukene ze-waveform, futhi imfuhlumfuhlu ngaphandle kwephutha elisobala lenjini akulula ukuyiqeda (okulungile kwezinye izimo), okungukuthi, lapho iziqongo zomuntu ngamunye ku-waveform azihlangene nephutha lenjini, mancane kakhulu amathuba okuthi ziqedwe ekulungiseni. Ukufingqa, umthetho wokwahlulela imfuhlumfuhlu yilokhu: Uma kungaphethwa ngokuthi akukho ukuvuza kwe-vacuum ku-multifold intake, okuqukethwe kwama-hydrocarbons (HC) nomoya-mpilo kugesi ephumayo kujwayelekile, futhi ukuzungezisa noma isivinini sokungenzi lutho injini ilinganiselwe, khona-ke imfuhlumfuhlu ingase yamukeleke noma ibe evamile.
