Chinotonhodza Mhepo Inopinda: Basa reMuchengeti weMasimba uye Zviratidzo zveMhosva
Mumhuri yemainjini ane turbocharged, mudziyo unotonhodza mweya unopinda mumotokari pasina mubvunzo ndiwo "muchengeti wesimba". Unoita sewakaderera asi une basa guru mukuwedzera simba uye kuchengetedza injini. Panguva imwe chete, kutadza kwayo kunogona kukanganisa mashandiro emotokari, zvichiita kuti vatyairi vagare vachiitarisa nguva dzese.
1. Intake Air Cooler: Core Assist yeTurbocharged Engines
Injini dzine turbocharger dzinowedzera huwandu hwemhepo inopinda nemhepo nekudzvanya mhepo, nokudaro zvichiwedzera simba. Zvisinei, panguva yekudzvanya, tembiricha yemhepo inokwira zvakanyanya, ichisvika 150°C kana kupfuura. Kuwedzera kwetembiricha kunoderedza huwandu hwemhepo uye huwandu hweokisijeni, zvichikanganisa kushanda zvakanaka kweinjini. Panguva iyi, chinhu chinotonhodza mhepo inopinda chinoshanda.
Basa guru remuchina wekutonhodza mweya nderekudzikisa tembiricha yemhepo yakamanikidzwa. Kuburikidza nemasisitimu ekutonhodza mweya kana ekutonhodza mvura, inogona kutonhodza mweya unopisa unopinda kusvika pa50-80°C. Mhepo inotonhora yakawanda inogona kuwedzera huwandu hwemhepo inopinda ne30%, zvichibvumira kupisa mafuta zvakakwana uye simba rakasimba. Data rinoratidza kuti pasi pemamiriro akafanana ehuwandu hwemhepo nemafuta, kudzikira kwega kwega kwe10°C mutembiricha yemhepo ine turbocharged kunogona kuwedzera simba reinjini ne3% kusvika 5%.
Pamusoro pekuwedzera simba, chinotonhodza mweya chinopinda muinjini ndicho "chinodzivirira" injini. Mhepo inopisa isina kutonhodzwa inopinda mukamuri rinopisa inokonzera kupisa kwakanyanya, zvichiwedzera zvakanyanya njodzi yekuputika, uye muzviitiko zvakakomba, zvinokuvadza mapiston, mavharuvhu, nezvimwe zvikamu. Chinotonhodza mweya chinopinda muinjini chinogona kuderedza mukana wekuputika neinopfuura 60%, uye tembiricha yemhepo inopinda muinjini inogonawo kuderedza huwandu hweNOx muutsi hweinjini, ichideredza utsi hunokuvadza ne20%-30%, zvichibatsira mota kusangana nezvinodiwa zvakasimba zveutsi.
Panyaya yekushandiswa kwemafuta, chitonhodzi chemhepo chinopinda mumhepo chinobatsirawo. Mhepo inotonhodzwa ine huwandu hwakanyanya inogona kuvandudza kushanda kweatomization yemafuta ne15%, pamwe chete nekudzora kwakaringana kwehuwandu hwemhepo nemafuta, zvichiita kuti pave nekuwedzera kwehuwandu hwemafuta hunoderedzwa ne5%-8%. Injini dzine turbocharged dzine matonhodzi emhepo anopinza dzinoshandisa mafuta mashoma ne10%-15% pane injini dzinozvibatidza dzega dzine simba rimwe chete. Munzvimbo dzakakwirira, chitonhodzi chemhepo chinopinza chinogona kuwedzera huwandu hwemafuta anopinza ne25%, pamwe chete nehigh compression ratio turbo, zvichideredza kurasikirwa kwesimba kubva pa35% kusvika pa15%, zvichibvumira mota kuchengetedza simba rakasimba kunyangwe mumigwagwa yakakwirira.
2. Kukanganisa Kunoitika: Zviratidzo Zvakajairika Zvekukundikana Kwemhepo Inotonhorera
Kana chinhu chinotonhodza mweya chikatadza kushanda, mota inobva yangotumira "chiratidzo chekuchengetedza" ipapo ipapo. Vatyairi vanofanira kungwarira matambudziko aya.
Kudzikira kwesimba ndiko kuratidzwa kuri pachena. Kana chitonhodzi chemhepo chinopinda chikatadza kushanda, mhepo inopisa haigoni kutonhodzwa zvinobudirira, zvichikonzera kudzikira kwehuwandu hwemhepo inopinda. Munguva yekumhanya nekukurumidza, turbo inopindura zvishoma nezvishoma, kumhanya kweinjini kunokwira asi kumhanya kwemotokari hakuwedzere zvakanyanya. Pakupfuura kana kukwira, pachava nekushaikwa kwesimba kunooneka. Mashandiro aimbove asina simba achava akaoma zvikuru, uye kutyaira zvakanaka kuchadzikira zvikuru.
Kuwedzera kukuru kwekushandiswa kwemafuta chiratidzo chinowanzoitika. Kutadza kushandisa mhepo inotonhorera kunokonzera kudzikira kwekushandisa mafuta, uye mafuta haagone kupiswa zvizere. Pasi pemakiromita akafanana, kuwanda kwekuwedzera mafuta kuchawedzera zvakanyanya, uye mutengo wekushandisa mota uchakwira zvakanyanya. Panguva imwe chete, kupisa kusina kukwana kuchakonzera utsi hutema muutsi, izvo zvinosvibisa nharaunda chete asiwo chiratidzo chekushanda zvisina kunaka kweinjini.
Chinotonhodza mweya chinopinda nepamusana peinjini chisina kushanda zvakanaka chinogonawo kukonzera kukuvara mukati meinjini. Kana chitonhodza mweya chikapinda nepamusana peinjini chichidonha zvakanyanya, zvidimbu zvejecha zvinogona kupinda mucylinder, zvichiwedzera kupera kwecylinder, zvichikonzera kusashanda zvakanaka kweinjini, kuzununguka kusingawanzoitiki, uye ruzha. Kupisa kusina kukwana kwenguva refu kunokonzera huwandu hwakawanda hwecarbon deposits pamavharuvhu nemisoro yemasilinda, zvichikonzera matambudziko ekupisa kweinjini, kusamira zvakanaka, uye kusvetuka zvisina kugadzikana pakumirira mwenje yemotokari. Mangwanani, zvinotora nguva yakareba kuti mota itange, uye kusamira zvakanaka pakumirira mwenje yemotokari.
Pamusoro pezvo, kuburikidza nekuona OBD, kuwedzera kusingawanzoitiki kwekupisa kwemhepo inopinda kunogona kuonekwa. Chinotonhodza mweya chinoshanda chinogona kutonhodza mweya wakamanikidzwa kubva pa200°C kusvika 50-80°C. Kana chisina kunaka, tembiricha yemhepo inopinda inogona kudarika 100°C, uye tembiricha yakakwira inoramba ichienderera mberi inokonzera kuputika. Nekufamba kwenguva, ichakuvadza piston nesirinda. Kana chinotonhodza chikadonha mumvura inotonhodza, kana paine mavara emafuta pamusoro pechinotonhodza mweya, zvinokanganisa kupisa uye zvinotungamira kune zvikanganiso zvakawanda.
III. Kugadzirisa Zuva Nezuva: Chengeta Intercooler "iri Pamhepo"
Kuti ive nechokwadi chekuti intercooler inoramba ichishanda, kugadzirisa kwezuva nezuva kwakakosha. Zvinokurudzirwa kuchenesa sinki yeintercooler yega yega makiromita zviuru makumi maviri, kunyanya mushure mekutyaira daro refu, kudzivirira guruva kuti risavhare uye kukanganisa kushanda zvakanaka kwekupisa. Panguva imwe chete, gara uchitarisa pombi yekupinda. Kana mavara emafuta akawanikwa, zvinogona kunge zvichikonzerwa nezvisimbiso zvekare, uye zvinoda kutsiviwa nenguva. Paunenge uchishandisa antifreeze muchando chekuchamhembe, sarudza specification ine ice point ye -35°C kudzivirira intercooler kuti isaome mukati.
Kuti uone kana intercooler iri kudonha mvura, unogona kuwedzera 2% sodium carbonate solution pa70 kusvika 80°C kune intercooler kusvika yazara. Mirira kwemaminitsi gumi nemashanu woona kana paine kudonha mvura. Kana paine kudonha mvura, inofanira kugadziriswa nenguva.
Kunyangwe intercooler isiriyo inonyanya kuoneka pamotokari, inoita basa rakakosha mukushanda kwemagetsi, kudzivirira injini, uye kuchengetedza mafuta. Kunzwisisa mashandiro ayo, kujairana nezviratidzo zvayo zvekukanganisa, uye kugadzirisa nguva dzose kunogona kuchengetedza injini ine turbocharger iri mumamiriro akanaka uye kupa mutyairi ruzivo rwekutyaira rwakanaka.
Kana uchida kuziva zvakawanda, ramba uchiverenga zvimwe zvinyorwa pane ino saiti!
Ndapota tifonerei kana muchida zvigadzirwa zvakadaro.
