Kodi ntchito ya chitoliro chotulutsa mpweya chotchedwa fyuluta ndi chiyani?
Chitoliro chotulutsa mpweya cha fyuluta ya mpweya chimagwira ntchito yopereka mpweya wosefedwa mkati mwa injini. Sikuti chimangothandiza kuchepetsa phokoso lomwe limabwera panthawi yolowetsa mpweya komanso chimaletsa kuwonongeka kwa injini chifukwa cha zinyalala. Chitoliro cholowetsa mpweya chimagwira ntchito bwino posefa fumbi ndi zinyalala mumlengalenga, kuonetsetsa kuti mpweya wolowa m'chipinda choyaka moto uli woyera kwambiri, motero kutsimikizira kuti mafuta onse amayaka. Pamene chinthu choyeretsera mpweya chidetsedwa chifukwa cha kuipitsidwa, chimalepheretsa kuyenda kwa mpweya, zomwe zimapangitsa kuti mphamvu ya injini ichepe ndipo motero zimakhudza mphamvu ya injini. Kuphatikiza apo, kapangidwe ka chipinda choyeretsera mpweya cholinga chake ndi kuchepetsa phokoso la injini. Nthawi zambiri chimayikidwa pa chitoliro cholowera mpweya ndipo chili ndi zibowo ziwiri zosiyana zomwe zimakhala zosavuta kuzizindikira.
Mu gawo la ukadaulo wa malo opangira magetsi a magalimoto, makamaka pakupanga zosefera mpweya zamagalimoto, kuchepetsa phokoso kwakhala chinthu chofunikira kuganizira. Ukadaulo wakumbuyo ukuwonetsa kuti phokoso lakhala vuto lalikulu lomwe likukhudza moyo wa anthu, ndipo makampani opanga magalimoto nawonso ndi osiyana. Ngakhale opanga magalimoto akuwonjezera magwiridwe antchito ena a magalimoto awo, adziperekanso kukonza magwiridwe antchito a NVH yamagalimoto awo. Monga njira yayikulu yolowera mpweya mu injini, fyuluta ya mpweya sikuti imangosefa fumbi kuchokera mumlengalenga kuti iteteze injini komanso imagwira ntchito ngati choletsa kukulira kuti ichepetse phokoso lolowera.
Komabe, mapangidwe a fyuluta ya mpweya yachikhalidwe nthawi zambiri amagwiritsa ntchito mabowo osavuta komanso mapaipi ozungulira amodzi kuti alowe ndi kutulutsa mpweya, opanda kusintha kwa magawo osiyanasiyana, motero amachepetsa kuwonjezeka kwa kukana kwa mawu komanso kusintha kwa zotsatira zochepetsera phokoso. Pakadali pano, ma fyuluta a mpweya awa nthawi zambiri amayikidwa pa batri ndi kutsogolo kwa baffle ndi mabowo. Kulimba kwa malo oyikako ndi kofooka, ndipo mapangidwe ambiri amalephera kuchepetsa phokoso lamagetsi. Ngakhale mapangidwe ena amaganizira kuchepetsa phokoso ndikuwonjezera mabowo ozungulira pa chitoliro chamagetsi, kuchita izi kudzakhala ndi malo ofunika kwambiri m'chipinda cha injini ndikubweretsa zovuta pa kapangidwe kake.
Mu patent ya "An Air Filter yokhala ndi Integrated Resonant Cavity", ngakhale kuti pali resonant cavity mkati mwa fyuluta ya mpweya kuti muchepetse phokoso, popeza gawo lopingasa la chitoliro cholowera silinasinthe, silingathandize kupititsa patsogolo kukweza kwa acoustic impedance kuti muchepetse phokoso. Kuphatikiza apo, kapangidwe kameneka sikaganizira za mphamvu ya kugwedezeka pa kutalika kwa kapangidwe kake. Ili ndi voliyumu yayikulu, yomwe siingathandize kapangidwe ka zowonjezera zina mu gawo la injini ndipo ingakhudzenso kuuma kwa malo oyika.
Poyankha mavutowa, njira yatsopanoyi ikupereka kapangidwe ka fyuluta ya mpweya yamagalimoto yomwe ingathandize kukonza phokoso la kulowa kwa mpweya. Kapangidwe kameneka kakuphatikizapo chipolopolo chapamwamba ndi chipolopolo chapansi. Chipolopolo chapansi chili ndi chipinda cholowera, chipinda cholumikizira, chipinda chosefera ndi chipinda chotulutsira mpweya. Mpweya umalowa kudzera mu cholowera mpweya, umadutsa m'zipinda izi motsatizana ndipo umatuluka kudzera mu chotulutsira mpweya. Chodziwika bwino n'chakuti, chipinda cholowera chapangidwa ngati chitoliro chomwe chimayikidwa mkati mwa cholumikizira, ndipo mbali imodzi ndi doko lolowera ndipo mbali inayo ili ndi dzenje lolumikizira lolumikizidwa ndi cholumikizira. Cholinga cha kapangidwe kameneka ndi kuchepetsa bwino phokoso la kulowa kwa mpweya.
Kufooka kwa mphamvu yamagetsi: Fyuluta ya mpweya imagwira ntchito yofunika kwambiri mu injini, yomwe imayang'anira kuyeretsa ndi kuyeretsa mpweya wolowa mu injini. Fyuluta ya mpweya ikangotuluka, kuchuluka kwa mpweya wolowa mu injini kumachepa, motero kumachepetsa mphamvu ya kuyaka ndikupangitsa mphamvu ya injini kuchepa.
Kuchuluka kwa mafuta ogwiritsidwa ntchito: Chifukwa cha kuchepa kwa mpweya wolowa mu injini, kuchuluka kwa mpweya wosakanikirana kudzawonjezeka moyenerera, zomwe zingayambitse kuyaka kosakwanira ndipo pambuyo pake zimapangitsa kuti mafuta agwiritsidwe ntchito mofulumira.
Ubwino wa mpweya wotulutsa utsi umachepa: Kusayaka mokwanira kudzapangitsa kuti mpweya woipa monga carbon monoxide ndi hydrocarbons mu mpweya wotulutsa utsi uwonjezereke, zomwe zingakhudze chilengedwe.
Kusagwira ntchito bwino kwa injini: Kutuluka kwa mpweya kuchokera mu fyuluta ya mpweya kungayambitse kusalowa bwino kwa mpweya mu injini, zomwe zingasokoneze ntchito yake yanthawi zonse ndipo zingachititse kuti injini isagwire bwino ntchito, kusagwira ntchito bwino, ndi zina zotero.
Kuchepa kwa kulimba kwa zigawo: Kuyaka kosakwanira kudzawonjezera vuto la carbon deposit mkati mwa injini, zomwe zidzafulumizitsa kuwonongeka kwa zigawo zofunika monga ma pistoni ndi ma valve, motero zimakhudza nthawi yawo yogwirira ntchito.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
Malingaliro a kampani Zhuo Meng Shanghai Auto Co., Ltd. yadzipereka kugulitsa zida zamagalimoto za MG&750 zolandiridwa kugula.
