Uyini umsebenzi wepayipi lokukhipha umoya elihlunga umoya
Ipayipi lokukhipha umoya lesihlungi somoya linesibopho sokuletha umoya ohlungiwe ngaphakathi kwenjini. Alisizi nje kuphela ukunciphisa umsindo okhiqizwa ngesikhathi sokungenisa kodwa futhi livimbela ukuguguleka nokulimala kwenjini okubangelwa ukungcola. Ipayipi lokungenisa lidlala indima ekuhlungeni ngempumelelo uthuli nokungcola emoyeni, liqinisekisa ukuthi umoya ongena ekamelweni lokushisa uhlanzekile kakhulu, ngaleyo ndlela liqinisekisa ukushiswa okuphelele kukaphethiloli. Lapho isici sesihlungi somoya singcola ngenxa yokungcola, sizophazamisa ukujikeleza komoya, okubangela ukwehla kwevolumu yokungenisa injini futhi ngaleyo ndlela kuthinte ukuphuma kwamandla enjini. Ngaphezu kwalokho, ukwakheka kwesikhala esiphendulayo sesihlungi somoya kuhlose ukunciphisa umsindo wokungenisa injini. Ngokuvamile sifakwa epayipini lokungenisa futhi sinezimbobo ezimbili ezihlukile okulula ukuzibona.
Emkhakheni wobuchwepheshe bezitshalo zamandla ezimoto, ikakhulukazi ekwakhiweni kwezihlungi zomoya zezimoto, ukunciphisa umsindo sekuyinto ebalulekile yokucatshangelwa. Ubuchwepheshe bangemuva bubonisa ukuthi umsindo usube yinkinga enkulu ethinta ikhwalithi yokuphila kwabantu, futhi imboni yezimoto nayo ayihlukile. Ngenkathi abenzi bezimoto bethuthukisa ezinye izici zokusebenza kwezimoto zabo, bazibophezele ekuthuthukiseni ukusebenza kwe-NVH kwezimoto zabo. Njengesango eliyinhloko lokungena komoya enjinini, isihlungi somoya asigcini nje ngokuhlunga uthuli emoyeni ukuze sivikele injini kodwa futhi sisebenza njengesivimbeli sokukhulisa ukuze kuncishiswe umsindo wokungenisa.
Kodwa-ke, imiklamo yendabuko yokuhlunga umoya ivame ukusebenzisa imigodi elula kanye namapayipi ajikelezayo alodwa okungenisa umoya kanye nokukhipha umoya, engenazo izinguquko ezinqamula isigaba, ngaleyo ndlela inciphise ukwanda kwe-acoustic impedance kanye nokuthuthukiswa kwemiphumela yokunciphisa umsindo. Okwamanje, lezi zihlungi zomoya zivame ukufakwa ebhethri kanye ne-baffle yangaphambili ngamabhawodi. Ukuqina kwamaphuzu okufaka kubuthakathaka kakhulu, futhi imiklamo eminingi yehluleka ukufeza ukunciphisa umsindo wokungenisa okuphumelelayo. Ngisho noma eminye imiklamo icabangela ukunciphisa umsindo futhi ingeze imigodi ezwakalayo epayipini lokungenisa, ukwenza kanjalo kuzothatha isikhala esibalulekile segumbi lenjini futhi kube yinselele ekwakhiweni.
Ku-patent ye-"An Air Filter with Integrated Resonant Cavity", yize i-resonant cavity ibekwe ngaphakathi kwe-air filter ukuze kuncishiswe umsindo, njengoba ingxenye yepayipi lokungenisa ingashintshi, ayikhuthazi ukwandisa i-acoustic impedance ukuze kuncishiswe umsindo. Ngaphezu kwalokho, lo mklamo awucabangi ngethonya lokudlidliza ekuphakameni kwesakhiwo. Inevolumu enkulu, engakhuthazi ukwakheka kwezinye izesekeli endaweni yenjini futhi ingathinta nokuqina kwendawo yokufaka.
Ukuphendula lezi zinkinga, lo mklamo uphakamisa isakhiwo sesihlungi somoya sezimoto esingathuthukisa umsindo wokungenisa umoya. Lesi sakhiwo sihlanganisa igobolondo eliphezulu negobolondo elingezansi. Igobolondo elingezansi lifakwe igumbi lokungenisa umoya, igumbi lokuzwana, igumbi lokuhlunga kanye negumbi lokukhipha umoya. Umoya ungena ngokungena komoya, udlule kula makamelo ngokulandelana bese ukhishwa ngombhobho womoya. Okuphawulekayo ukuthi igumbi lokungenisa umoya lakhiwe njengepayipi elibekwe ngaphakathi komgoqo we-resonant, kanti uhlangothi olulodwa luyi-port yokungenisa umoya kanti olunye uhlangothi lunembobo yokuxhuma exhunywe emgodini we-resonant. Lo mklamo uhlose ukunciphisa ngempumelelo umsindo wokungenisa umoya.
Ukusebenza kohlelo lwamandla olubuthakathaka: Isihlungi somoya sidlala indima ebalulekile enjinini, sinomthwalo wokuhlola nokuhlanza umoya ongena enjinini. Uma isihlungi somoya sivuza, inani lomoya ogeleza enjinini lizoncipha, ngaleyo ndlela linciphise ukusebenza kahle kokushisa futhi kubangele amandla okukhipha enjini ehle.
Ukusetshenziswa kukaphethiloli okwandisiwe: Ngenxa yokwehla kwenani lomoya ongena enjinini, ubuningi begesi exubile buzokhula ngokufanele, okuzobangela ukusha okungaphelele futhi kamuva kuholele esilinganisweni esisheshayo sokusetshenziswa kukaphethiloli.
Ikhwalithi yegesi yokukhipha umoya iyawohloka: Ukusha okungaphelele kuzobangela ukwanda kokukhishwa kwezinto ezingcolisayo njenge-carbon monoxide nama-hydrocarbons egesini yokukhipha umoya, okunomthelela omubi emvelweni.
Ukusebenza kwenjini okungazinzile: Ukuvuza komoya okuvela esihlungini somoya kungabangela ukungena komoya okwanele enjinini, okuphazamisa ukusebenza kwayo okuvamile futhi okungase kuholele ekumisweni, ekungahlali kahle kwenjini, nakwezinye izimo.
Ukuqina okunciphile kwezingxenye: Ukusha okungaphelele kuzokwandisa inkinga yediphozithi yekhabhoni ngaphakathi kwenjini, okuzosheshisa ukuguguleka kwezingxenye ezibalulekile njengepiston namavalvu, ngaleyo ndlela kuthinte impilo yazo yokusebenza.
