Ntchito yaikulu ya msonkhano wa fyuluta ya mpweya wamagalimoto
Chopangira fyuluta ya mpweya yamagalimoto chimaonedwa ngati "choteteza chosaoneka" cha injini. Pakugwira ntchito kwa galimoto, chimagwira ntchito zingapo zofunika.
Choyamba, imagwira ntchito ngati "chishango" cha zigawo zolondola za injini. Zosefera mpweya zabwino kwambiri zimatha kusefa zonyansa zoposa 99% zokhala ndi mainchesi ≥ 5, zomwe zimathandiza kuti tinthu tolimba monga fumbi, mchenga, mungu, ndi zina zotero zisalowe mu silinda, motero kupewa kuwonongeka kwa zinthu monga ma pistoni, makoma a silinda, ndi ma valve chifukwa cha kulowa kwa zinthu zonyansa. Ngati fyuluta ya mpweya yatsekedwa kwa nthawi yayitali, kuchuluka kwa kuwonongeka kwa injini kudzawonjezeka ndi nthawi 3 - 5, zomwe zimawonjezera chiopsezo chokoka silinda, kuyaka mafuta, ndi zolakwika zina. M'malo ouma komanso amchenga, popanda chitetezo cha fyuluta ya mpweya, tinthu tating'onoting'ono tomwe timalowa pakati pa pistoni ndi silinda tingayambitsenso "kukoka silinda" kwambiri.
Kachiwiri, izi zikugwirizana ndi mphamvu ya galimoto komanso kugwiritsa ntchito mafuta moyenera. Pamene fyuluta ya mpweya yatsekedwa kufika pa 30%, kukana kwa injini kulowa kudzawonjezeka kwambiri, zomwe zimapangitsa kuti injini isagwiritse ntchito mafuta okwanira. Panthawiyi, ECU idzasintha kuchuluka kwa mafuta omwe amalowa kuti injini ipitirize kuyaka, koma kusalinganika kwa kuchuluka kwa mafuta osakaniza kudzachepetsa mphamvu ya mafuta ndi 5% - 10%, ndipo kugwiritsa ntchito mafuta pa makilomita 100 kudzawonjezeka ndi kupitirira lita imodzi. Ngakhale fyuluta ya mpweya yogwira ntchito bwino ingatsimikizire kuti mpweya wolowa mu injini ndi woyera komanso wokwanira, zomwe zimathandiza kuti mafuta ndi mpweya zizigwiritsidwa ntchito bwino kuti zigwiritsidwe ntchito bwino, zomwe zimathandiza kuti injini izigwira ntchito bwino komanso kuti mafuta azigwiritsidwa ntchito bwino.
Kuphatikiza apo, ndikofunikira kwambiri pakukonza malo oyatsira moto ndikuwonjezera moyo wa ntchito ya mafuta a injini. Mpweya woyera wolowera ukhoza kuchepetsa 50% kapena kuposerapo kwa mpweya woipa pa valavu yolumikizira, ma spark plugs, ndi chipinda choyatsira moto, kuchepetsa mwayi wogwedezeka, kufooka kwa liwiro, ndi zina zotero chifukwa cha mpweya woipa. Zonyansa zosasefedwa zomwe zimalowa mu injini zidzasakanikirana ndi mafuta a injini, zomwe zimafulumizitsa okosijeni ndi kuipitsa kwake. Kusefa kogwira mtima kumatha kubwezeretsa kayendedwe ka mafuta wamba amchere kuchokera pa makilomita 3,000 kufika pa makilomita pafupifupi 7,500, ndipo kayendedwe ka mafuta opangidwa mokwanira kangathenso kukulitsidwa moyenerera, kuchepetsa ndalama zokonzera ndi pafupifupi 60%.
Kuphatikiza apo, zinthu zina zolumikizira mpweya zomwe zimagwirizana zingathandizenso kuyeretsa mpweya wamkati, kuteteza zinthu zoopsa monga PM2.5, mungu, mankhwala a sulfure, ndi zina zotero, kupanga malo abwino komanso omasuka okwera, makamaka othandiza kwa anthu omwe ali ndi ziwengo. Nthawi yomweyo, ilinso ndi mphamvu yochepetsera phokoso, yomwe imayamwa ndikuletsa phokoso lochokera ku injini kuti malo amkati akhale chete.
Zolakwika ndi zotsatira za msonkhano wa fyuluta ya mpweya wamagalimoto
Pakagwiritsidwa ntchito kwa nthawi yayitali, chipangizo chopangira mpweya wa magalimoto chingathenso kukumana ndi zolakwika zosiyanasiyana, zomwe zingabweretse mavuto pa ntchito ya galimoto.
Vuto lalikulu kwambiri ndi kutsekeka kwa mpweya. Pamene nthawi yogwiritsira ntchito ikuwonjezeka, zinyalala mumlengalenga zidzasonkhana pang'onopang'ono pa fyuluta ya mpweya, kutseka ma pores ake ndikuwonjezera kukana kwa mpweya kulowa. Izi zipangitsa kuti injini isalowe mokwanira, mphamvu zochepa zotulutsa, komanso zinthu monga kuthamanga pang'onopang'ono komanso kuyankha pang'onopang'ono poponda accelerator, makamaka ikadutsa kapena kuthamanga kwambiri. Nthawi yomweyo, mafuta sangatenthedwe mokwanira, zomwe zimapangitsa kuti mafuta azitayika, mafuta azigwiritsidwa ntchito ndi 5% - 20%, komanso malita 3 - 5 owonjezera pamagalimoto a dizilo. Pakapita nthawi, mpweya woipa mkati mwa injini udzapangika, zomwe zidzafulumizitse kuwonongeka kwa zigawo ndikukhudza magwiridwe antchito a injini komanso moyo wake.
Kuwonongeka ndi vuto lomwe silinganyalanyazidwe. Magalimoto odutsa m'magawo obowoka, kukhudzidwa ndi mphamvu zakunja, kapena kugwira ntchito movutikira kwa nthawi yayitali angayambitse kuti chimango cha fyuluta ya mpweya chiwonongeke kapena kuti mipata isweke. Panthawiyi, mpweya wosasefedwa udzalowa mwachindunji mu injini, ndi tinthu tating'onoting'ono toposa 0.5 micrometers tikulowa m'chipinda choyaka moto, zomwe zikufanana ndi kutsanulira pafupifupi magalamu 5 a zinyalala za sandpaper mu injini patsiku, zomwe zimawonjezera kuchuluka kwa kuwonongeka kosazolowereka kwa makoma a silinda ndi mphete za pistoni ndi nthawi 6. Choopsa kwambiri, chinyezi chosasefedwa chidzagwirizana ndi zitsulo zosungunuka kuti zipange hydrochloric acid yowononga, zomwe zimapangitsa kuti thupi la silinda likhale lopanda mphamvu.
Chinyezi chimakhudzanso ntchito yachizolowezi ya fyuluta ya mpweya. Mukagwiritsa ntchito galimoto pamalo onyowa kapena kudutsa m'malo odzaza madzi, ngati chisindikizo cha fyuluta ya mpweya sichili cholimba, chinyezi chingalowe mkati mwa fyuluta, zomwe zimapangitsa kuti inyowe. Kugwira ntchito kwa fyuluta ya mpweya wonyowa kudzachepa ndipo kungayambitse kukula kwa nkhungu. Kukula kwa nkhungu kumakhala katatu kuposa momwe zinthu zilili. Pakatha maola 24, mawanga owoneka a nkhungu amatha kupangika. Nkhunguzi sizimangowononga kapangidwe ka pepala la fyuluta ndikuchepetsa mphamvu yosefera ndi 30%, komanso zimapanga tizilombo toyambitsa matenda kudzera mu dongosolo lolowera lomwe lingalowe m'chipinda cha galimoto. Kupuma kwa nthawi yayitali kungayambitse matenda a rhinitis ndi matenda opuma.
Kupewa ndi kuyankha kulephera kwa kusonkhana kwa fyuluta ya mpweya
Pofuna kupewa kulephera kwa fyuluta ya mpweya kusokoneza magwiridwe antchito a magalimoto, eni magalimoto ayenera kusamala ndi kukonza tsiku ndi tsiku. Kawirikawiri, magalimoto omwe akuyenda m'mizinda ayenera kusinthidwa ma fyuluta awo a mpweya makilomita 1 - 2 aliwonse; pamagalimoto omwe akuyenda m'malo afumbi, nthawi yosinthira iyenera kuchepetsedwa kufika makilomita 5000 kapena miyezi itatu. Pakukonza tsiku ndi tsiku, ndikofunikira kuyang'ana ukhondo ndi kukhulupirika kwa fyuluta ya mpweya. Ma fyuluta a mapepala amatha kutsukidwa kuchokera mkati pogwiritsa ntchito mpweya wopanikizika, ndipo kutsuka m'madzi n'koletsedwa; ma fyuluta okhala ndi mafuta amafunika zotsukira zapadera ndi mafuta osamalira kuti azikonzedwa. Ngati mupeza kuti fyuluta ya mpweya yakhala yakuda komanso yodetsedwa, yawonongeka komanso ikutuluka madzi, kapena ili ndi zizindikiro zochenjeza monga kuchepa kwa mphamvu, kuchuluka kwa mafuta, komanso utsi wakuda, muyenera kusintha fyuluta nthawi yomweyo.
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 MG&MAXUSzida zamagalimoto zalandiridwa kugula.
