Kiti Yowerengera Nthawi ya Magalimoto: Choyang'anira Cholondola ndi Chowunikira Cholakwika cha Injini
Mu dongosolo lovuta la injini ya galimoto, zida zowerengera nthawi zimakhala ngati chotetezera cholondola, chomwe chimaonetsetsa kuti mphamvu ikuyenda bwino komanso kuti igwire bwino ntchito. Si chinthu chimodzi chokha, koma ndi dongosolo lathunthu lopangidwa ndi zigawo zazikulu monga malamba owerengera nthawi kapena maunyolo, zotenthetsera, mawilo otenthetsera, ndi mawilo otayira. Zigawozi zimagwirira ntchito limodzi kuti zipange moyo wa valavu ya injini.
Kuchokera pa mfundo yogwirira ntchito, mu injini ya ma stroke anayi, kulowetsa, kukakamiza, kupanga mphamvu, ndi kutulutsa mphamvu kumafunikira kuyenda kogwirizana kwa ma valve ndi ma pistoni. Kiti yowerengera nthawi imawongolera nthawi yotsegulira ndi kutseka ma valve polumikiza crankshaft ndi camshaft. Panthawi yolowetsa mphamvu, imalola valavu yolowera kutseguka panthawi yoyenera, kulola kuti chisakanizo chatsopano chilowe mokwanira mu silinda; pambuyo pa kulowetsa mphamvu, imayang'anira bwino kutseguka kwa valavu yotulutsa mphamvu kuti itulutse mpweya wotulutsa mphamvu mwachangu. Kugwirizana kolondola kumeneku sikungotsimikizira kutulutsa bwino mphamvu ya injini komanso kumachepetsa kugwiritsa ntchito mafuta ndikuchepetsa kutulutsa mpweya wotulutsa mpweya. Kwa injini za turbocharged, kulondola kwa kiti yowerengera nthawi ndikofunikira kwambiri. M'malo ogwirira ntchito mwachangu, kusintha kulikonse pang'ono kumatha kubweretsa kutayika kwa mphamvu kapena kuwonongeka kwa zigawo.
Komabe, zida zogwiritsira ntchito nthawi ndi gawo lotha ntchito mgalimoto. Pamene nthawi yogwiritsira ntchito ikuwonjezeka, zoopsa za zolakwika zimaonekera pang'onopang'ono. Vuto lofala kwambiri ndi kusweka kwa lamba wa nthawi kapena kulumpha kwa unyolo. Lamba wa nthawi nthawi zambiri amapangidwa ndi rabara ndipo amagwira ntchito pamalo otentha kwambiri komanso oipitsidwa ndi mafuta, pang'onopang'ono amakalamba ndikusweka. Akangosweka poyendetsa, pa injini zamtundu wa kusokoneza, ma valve ndi ma piston adzagundana nthawi yomweyo, zomwe zimapangitsa kuti ma valve agwedezeke ndi kuwonongeka kwa piston, ndipo injini ikhoza kutayidwa mwachindunji. Ngakhale pa injini zosasokoneza, sitima ya valve imasiya kugwira ntchito mwadzidzidzi, zomwe zimapangitsa kuti injini izimitsidwe mwadzidzidzi, zomwe zimawopseza kwambiri chitetezo choyendetsa. Kulephera kwa tensioner ndi vuto lofala la zida zogwiritsira ntchito nthawi. Ntchito ya tensioner ndikupereka mphamvu yoyenera ya lamba kapena unyolo. Ngati kusinthasintha kwake kwa masika sikukwanira kapena mafuta a hydraulic atatuluka, lamba kapena unyolo udzakhala womasuka. Zingayambitse phokoso la "kudina" kapena "kufuula" m'malo ofatsa, kapena kutsogolera ku kulumpha kapena kugawanika kwa zigawo m'malo ovuta. Kuphatikiza apo, kuwonongeka kwa zinthu monga mawilo osagwira ntchito ndi ma chain plates kungasokonezenso kukhazikika kwa dongosolo la nthawi, zomwe zimayambitsa phokoso losazolowereka komanso kusagwira bwino ntchito. Zizindikiro zoyambirirazi nthawi zambiri zimakhala zazing'ono ndipo zitha kunyalanyazidwa mosavuta ndi eni magalimoto, koma ngati sizingathetsedwe mwachangu, mavuto ang'onoang'ono amatha kukulirakulira kukhala zolakwika zazikulu, ndipo mtengo wokonzanso udzawonjezekanso kwambiri.
Kuti mupewe kutayika komwe kumachitika chifukwa cha kulephera kwa zida zosungira nthawi, eni magalimoto ayenera kutsatira malangizo omwe ali m'buku lowongolera magalimoto. Lamba wosunga nthawi nthawi zambiri amasinthidwa makilomita 5 - 10,000 aliwonse, ndipo pa mitundu ina, amatha kuchepetsedwa kufika makilomita 6,000; unyolo wosunga nthawi, ngakhale kuti sufuna kusinthidwa nthawi zonse, uyeneranso kuyesedwa mwapadera makilomita 5,000 aliwonse. Mukasintha zida zosungira nthawi, ndikofunikira kusankha zida zoyambirira kapena zapamwamba kuti mupewe zolakwika zina zomwe zimachitika chifukwa cha zida zatsopano ndi zakale zosagwirizana. Mukamayendetsa galimoto tsiku lililonse, samalani ndi mawonekedwe osazolowereka a injini, monga kutayika kwadzidzidzi kwa mphamvu, kugwedezeka kosagwira ntchito, kapena phokoso losadziwika bwino. Mavuto akapezeka, pitani mwachangu kukawafufuza ku malo okonzera akatswiri.
Ngakhale kuti zida zosungira nthawi zimabisika mkati mwa injini, zimagwirizana mwachindunji ndi mphamvu ya galimoto komanso chitetezo cha galimotoyo. Kumvetsetsa ntchito yake ndi zolakwika zomwe zimachitika kawirikawiri, komanso kugogomezera kukonza nthawi zonse, kungatsimikizire kuti injiniyo ikhalabe yamphamvu komanso imapereka chidziwitso choyendetsa bwino.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
