Kodi choziziritsira mkati n'chiyani?
Choziziritsira ndi chipangizo choyeretsera kutentha chomwe chimagwiritsidwa ntchito kuchepetsa kutentha kwa mpweya wolowa mu injini. Chimagwiritsidwa ntchito makamaka mu injini zokhala ndi turbocharged kapena supercharged, zomwe zimapangitsa kuti injini izigwira ntchito bwino komanso kukhazikika mwa kuziziritsa mpweya wotentha kwambiri pambuyo powonjezera mphamvu.
Ntchito yaikulu ya intercooler ndi
Intercooler ndi gawo lofunika kwambiri mu injini ya turbocharger. Ntchito yake yayikulu ndikuchepetsa kutentha kwa mpweya wotentha kwambiri pambuyo pa turbocharging kudzera mu mfundo yosinthira kutentha. Panthawi yokonza turbocharging kapena mechanical supercharging, kupsinjika kwa mpweya kungayambitse kutentha kwakukulu (mpaka kupitirira 200℃). Ngati italowa mwachindunji m'chipinda choyaka moto, imayambitsa kugogoda, kuchepetsa mphamvu yochajira ndikuwonjezera mpweya woipa. Intercooler imatha kuchepetsa kutentha kwa mpweya wolowa ndi madigiri 50 mpaka 60 Celsius, kuwonjezera kuchuluka kwa mpweya, ndikuwonjezera mphamvu ya injini ndi 3% mpaka 5%.

Mfundo yogwirira ntchito ya Youdaoplaceholder0 .
Choziziritsira chimasinthasintha kutentha ndi mpweya wopanikizika wotentha kwambiri kudzera mu choziziritsira (mpweya kapena madzi). Mpweya wopanikizika umadutsa m'mapaipi otaya kutentha a choziziritsiracho, komwe kutentha kumatengedwa ndi mpweya wakunja kapena choziziritsira. Mpweya wozizirawo umalowa m'chipinda choyaka cha injini.
Mtundu woziziritsidwa ndi mpweya: Umagwiritsa ntchito mpweya woyenda kapena kuziziritsa kwa fan pamene galimoto ikuyenda. Ili ndi kapangidwe kosavuta koma kogwira ntchito kochepa pa liwiro lotsika.
Mtundu woziziritsidwa ndi madzi: Umachotsa kutentha kudzera mu kayendedwe ka choziziritsira cha injini. Mphamvu yoziziritsira imakhala yokhazikika koma kapangidwe kake ndi kovuta.
Youdaoplaceholder0 Zipangizo ndi kapangidwe kake.
Kawirikawiri imapangidwa ndi aluminiyamu chifukwa cha kutentha kwake kwabwino kwambiri. Kapangidwe kake kamafunika kulinganiza bwino kuziziritsa ndi kukana mpweya. Choziziritsira chachikulu kwambiri chingapangitse kuti turbine isamavutike.
Mtengo wogwiritsira ntchito wa Youdaoplaceholder0
Youdaoplaceholder0 Kuwongolera magwiridwe antchito : Kuchepetsa kutentha kwa mpweya wolowa kungathandize kukweza mphamvu ya mpweya, kuwonjezera mphamvu yotulutsa komanso kuchepetsa kugwiritsa ntchito mafuta.
Youdaoplaceholder0 Tetezani injini : pewani kugogoda ndi kuwonongeka kwa makina komwe kumachitika chifukwa cha kutentha kwambiri, ndikuwonjezera nthawi ya moyo wa injini.
Youdaoplaceholder0 Ubwino wa chilengedwe : Amachepetsa mpweya wa nayitrogeni oxide (NOx), zomwe zimakwaniritsa zofunikira zoteteza chilengedwe.
Ntchito yaikulu ya intercooler ndikuchepetsa kutentha kwa mpweya wolowa mu injini ya turbocharged, kuwonjezera kuchuluka kwa mpweya wolowa, motero kumawonjezera mphamvu yoyaka komanso kutulutsa mphamvu, pamene akuletsa kugogoda ndikuchepetsa mpweya woipa.
Ntchito yaikulu ndi njira yogwirira ntchito ya intercooler
Youdaoplaceholder0 kuziziritsa mpweya wopanikizika .
Panthawi ya turbocharging, kutentha kwa mpweya wopanikizika kumakwera kwambiri (nthawi zambiri kufika pa 120℃), zomwe zimapangitsa kuti kuchuluka kwa mpweya kuchepe. Choziziritsiracho chimachepetsa kutentha kwa mpweya wolowera kufika pa 50-60℃ kudzera mu kutentha, zomwe zimapangitsa kuti kuchuluka kwa mpweya kuwonjezereke ndi pafupifupi 30%.
Deta yoyesera ikuwonetsa kuti pa kutentha kulikonse kwa mpweya wolowa mkati mwa 10℃, mphamvu ya injini imatha kuwonjezeka ndi 3% mpaka 5%.
Youdaoplaceholder0 imawonjezera mphamvu yoyaka.
Mpweya wotentha pang'ono komanso wolemera kwambiri umathandiza kuti mafuta azitha kusungunuka bwino, kuwongolera bwino kuchuluka kwa mpweya ndi mafuta, komanso kuyaka kwathunthu. Izi sizimangowonjezera mphamvu yotulutsa komanso zimachepetsa kugwiritsa ntchito mafuta ndi pafupifupi 5% mpaka 10%.
Youdaoplaceholder0 imaletsa magwiridwe antchito osazolowereka a injini.
Chotsani zinthu zomwe zimayambitsa kutentha kwambiri komanso kugwedezeka kwa mpweya kuti mupewe kuwonongeka kwa zinthu zofunika kwambiri monga ma pistoni ndi ma valve.
Chepetsani mpweya wa nitrogen oxide (NOx) ndi 20% mpaka 30% kuti mukwaniritse miyezo yokhwima yoteteza chilengedwe.

Youdaoplaceholder0 chipukuta misozi chapamwamba .
M'malo okwera mamita 3,000, choziziritsira mpweya chimatha kusunga pafupifupi 85% ya mphamvu ya makina oziziritsira mpweya pansi pa mikhalidwe yosalala, ndipo kuchepa kwa magwiridwe antchito a makina oziziritsira mpweya popanda choziziritsira mpweya kumachepetsedwa ndi 40%.
Youdaoplaceholder0 kukonza mgwirizano wa dongosolo .
Magawo okhazikika a intake pambuyo poziziritsa amalola turbocharger kufanana ndi chiŵerengero chapamwamba cha compression (nthawi zambiri chimawonjezeka ndi 15% mpaka 20%), zomwe zimapangitsa kuti pakhale mgwirizano wabwino pakati pa turbocharging system ndi injini.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
