Choziziritsira Mpweya Cholowa: Udindo wa Woyang'anira Mphamvu ndi Zizindikiro Zolakwika
Mu banja la injini zokhala ndi turbocharged, choziziritsira mpweya cholowera mkati mosakayikira ndi "choteteza mphamvu". Chimawoneka chodzichepetsa koma chimagwira ntchito yofunika kwambiri pakuwonjezera mphamvu ndikuteteza injini. Nthawi yomweyo, kulephera kwake kungakhale ndi zotsatirapo zoipa zambiri pa magwiridwe antchito a galimoto, zomwe zimafuna kuti oyendetsa galimoto aziyang'anira nthawi zonse.
1. Choziziritsira Mpweya Cholowa: Chithandizo Chachikulu cha Ma Injini Okhala ndi Turbocharged
Mainjini okhala ndi turbocharger amawonjezera kuchuluka kwa mpweya wolowa mwa kukanikiza mpweya, motero amawonjezera mphamvu. Komabe, panthawi yokanikizidwa, kutentha kwa mpweya kumakwera kwambiri, kufika pa 150°C kapena kuposerapo. Kuwonjezeka kwa kutentha kumachepetsa kuchuluka kwa mpweya ndi mpweya, zomwe zimakhudza mphamvu ya injini yochajira. Pakadali pano, choziziritsira mpweya cholowa chimayamba kugwira ntchito.
Ntchito yaikulu ya choziziritsira mpweya cholowa ndi kuchepetsa kutentha kwa mpweya wopanikizika. Kudzera mu makina oziziritsira mpweya kapena oziziritsira madzi, imatha kuziziritsa mpweya wotentha wolowa mpaka 50-80°C. Mpweya wozizira kwambiri ukhoza kuwonjezera kuchuluka kwa mpweya wolowa ndi pafupifupi 30%, zomwe zimapangitsa kuti mafuta aziyaka bwino komanso mphamvu zituluke mwamphamvu. Deta ikuwonetsa kuti pansi pa mikhalidwe yofanana ya chiŵerengero cha mpweya ndi mafuta, kuchepa kulikonse kwa kutentha kwa mpweya wa turbocharged pa 10°C kumatha kuwonjezera mphamvu ya injini ndi 3% mpaka 5%.
Kuwonjezera pa kukulitsa mphamvu, choziziritsira mpweya cholowera ndi "choteteza" injini. Mpweya wotentha wosazizira womwe umalowa m'chipinda choyaka moto umayambitsa kutentha kwambiri, zomwe zimawonjezera chiopsezo cha kuphulika, ndipo nthawi zina, zimawononga ma pistoni, ma valve, ndi zinthu zina. Choziziritsira mpweya choloweracho chingachepetse mwayi wophulika ndi 60%, ndipo kutentha kwa mpweya wolowera kokhazikika kungachepetsenso kuchuluka kwa NOx mu utsi wa injini, kuchepetsa mpweya woipa ndi 20%-30%, kuthandiza magalimoto kukwaniritsa miyezo yokhwima ya utsi.
Ponena za kugwiritsa ntchito mafuta mopanda mphamvu, choziziritsira mpweya cholowa nachonso chimathandizira. Mpweya wozizira kwambiri ukhoza kupititsa patsogolo mphamvu ya atomization ya mafuta ndi 15%, kuphatikiza ndi kuwongolera molondola kwa chiŵerengero cha mpweya ndi mafuta, zomwe zimapangitsa kuti mafuta azigwiritsidwa ntchito mopanda mphamvu ndi 5%-8%. Mainjini okhala ndi turbocharger okhala ndi zoziziritsira mpweya zolowa amadya mafuta ochepa ndi 10%-15% kuposa mainjini omwe amadziyatsira okha a mphamvu yomweyo. M'malo okwera kwambiri, choziziritsira mpweya cholowa chikhoza kuwonjezera kuchuluka kwa mafuta olowa ndi 25%, kuphatikiza ndi turbo yowonjezereka, kuchepetsa kutayika kwa mphamvu kuchokera pa 35% mpaka 15%, zomwe zimathandiza magalimoto kukhala ndi mphamvu zolimba ngakhale m'misewu yayitali.
2. Kulephera kwa Cholakwika: Zizindikiro Zachizolowezi za Kulephera kwa Choziziritsira Mpweya Cholowa
Choziziritsira mpweya cholowera chikalephera, galimotoyo imatumiza nthawi yomweyo "chizindikiro chachitetezo". Oyendetsa galimoto ayenera kusamala ndi zovuta izi.
Kuchepa kwa mphamvu ndi chizindikiro chodziwikiratu. Pamene choziziritsira mpweya cholowera chalephera, mpweya wotentha sungathe kuziziritsidwa bwino, zomwe zimapangitsa kuti kuchuluka kwa mpweya wolowera kuchepe. Pakuthamanga mofulumira, turbo imayankha pang'onopang'ono, liwiro la injini limakwera koma liwiro la galimoto silimawonjezeka kwambiri. Pakupitirira kapena kukwera, padzakhala kusowa kwa mphamvu koonekeratu. Ntchito zomwe kale zinali zosavuta zidzakhala zovuta kwambiri, ndipo kuyendetsa bwino kudzachepa kwambiri.
Kuwonjezeka kwakukulu kwa kugwiritsa ntchito mafuta ndi chizindikiro chofala. Kulephera kugwiritsa ntchito mpweya woziziritsa mpweya kungayambitse kuchepa kwa kugwiritsa ntchito bwino mafuta, ndipo mafuta sangatenthedwe kwathunthu. Pa nthawi yomweyi, kuchuluka kwa mafuta kudzawonjezeka kwambiri, ndipo mtengo wogwiritsa ntchito galimoto udzakwera kwambiri. Nthawi yomweyo, kuyaka kosakwanira kudzayambitsa utsi wakuda mu utsi wotulutsa mafuta, womwe sumangodetsa chilengedwe komanso ndi chizindikiro chodziwikiratu cha ntchito yosazolowereka ya injini.
Choziziritsira mpweya cholowa m'malo chomwe sichikugwira ntchito bwino chingawonongenso mkati mwa injini. Ngati choziziritsira mpweya cholowa m'malocho chikutuluka kwambiri, tinthu ta mchenga tingalowe mu silinda, zomwe zimapangitsa kuti silinda iwonongeke kwambiri, zomwe zimayambitsa kusagwira bwino ntchito kwa injini, kugwedezeka kosazolowereka, ndi phokoso. Kuyaka kosakwanira kwa nthawi yayitali kungayambitse kuchuluka kwa mpweya woipa pa ma valve ndi mitu ya masilinda, zomwe zimapangitsa kuti injini ikhale yovuta kuyatsa, kusakhazikika, komanso kulumpha kosakhazikika poyembekezera magetsi a pamsewu. M'mawa, zimatenga nthawi yayitali kuyambitsa galimoto, ndipo chokhazikikacho chidzakhala chosakhazikika poyembekezera magetsi a pamsewu.
Kuphatikiza apo, kudzera mu kuzindikira kwa OBD, kukwera kosazolowereka kwa kutentha kwa mpweya wolowa kumatha kudziwika. Choziziritsira mpweya chogwira ntchito chimatha kuziziritsa mpweya wopanikizika kuyambira 200°C mpaka 50-80°C. Ngati chili ndi vuto, kutentha kwa mpweya wolowa kumatha kupitirira 100°C, ndipo kutentha kwakukulu kosalekeza kumayambitsa kuphulika. Pakapita nthawi, kudzawononga pistoni ndi silinda. Ngati choziziritsiracho chikutuluka mu choziziritsira chozizira ndi madzi, kapena ngati pali madontho a mafuta pamwamba pa choziziritsira chozizira ndi mpweya, zidzakhudza momwe kutentha kumatayikira ndipo zingayambitse zolakwika zingapo.
III. Kukonza Tsiku ndi Tsiku: Sungani Intercooler "Pa intaneti"
Kuti muwonetsetse kuti intercooler ikugwira ntchito mosalekeza, kukonza tsiku ndi tsiku ndikofunikira. Ndikofunikira kuyeretsa sinki yotenthetsera ya intercooler makilomita 20,000 aliwonse, makamaka mutayendetsa mtunda wautali, kuti fumbi lisatseke ndikusokoneza mphamvu yotaya kutentha. Nthawi yomweyo, yang'anani nthawi zonse chitoliro cholowera. Ngati mafuta apezeka, mwina chifukwa cha zisindikizo zakale, ndipo ziyenera kusinthidwa pakapita nthawi. Mukagwiritsa ntchito antifreeze kumpoto kwa nyengo yozizira, sankhani zomwe zili ndi ayezi wa -35°C kuti intercooler isazizire mkati.
Kuti muwone ngati choziziritsiracho chikutuluka madzi, mutha kuwonjezera yankho la 2% sodium carbonate pa 70 mpaka 80°C ku choziziritsiracho mpaka chitadzaza. Dikirani kwa mphindi 15 ndikuwona ngati pali kutayikira kulikonse. Ngati pali kutayikira, chiyenera kukonzedwa nthawi yake.
Ngakhale kuti intercooler si chinthu chodziwika bwino pa galimoto, imagwira ntchito yofunika kwambiri pa mphamvu zamagetsi, kuteteza injini, komanso kuchepetsa mafuta. Kumvetsa ntchito yake, kudziwa bwino zizindikiro zake zolakwika, komanso kukonza nthawi zonse kungathandize kuti injini ya turbocharged ikhale bwino komanso kupatsa dalaivala mwayi woyendetsa bwino.
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.
