Zinthu Zofunika Posankha Turbocharger

Kusankha turbocharger yoyenera ya injini yanu kumaphatikizapo zambiri.

Sikuti zowona za injini yanu ndizofunikira, komanso zofunikanso ndikugwiritsa ntchito injiniyo. Njira yofunikira kwambiri pamalingaliro awa ndi malingaliro enieni. Mwanjira ina, ngati mukupanga turbocharging injini yomwe pano ili ndi mphamvu ya 200 hp momwe imafunira mwachilengedwe, mungakonde kuti ipange 600 hp. Komabe, izi zitha kukhala zosatheka mkati mwazowonjezera zosintha zomwe mukufuna kuchita. Ngati mukuyang'ana chiwonjezeko chabwino chamagetsi pakuyendetsa mozungulira mumsewu, kuwonjezeka kwa 50 peresenti ndikowonadi ndipo kufananiza turbo ndi kuchuluka uku kumabweretsa zotsatira zokhutiritsa. Kuwonjezeka kwa mphamvu kwa 300 peresenti (200 mpaka 600 hp) n'kotheka m'mainjini ambiri, koma kuwonjezereka kotereku kumasungidwa kwa injini za mpikisano zomwe zimakhala ndi zowonjezera zowonjezera, mkati ndi kunja, zomwe zonse zimagwirira ntchito limodzi kuti akwaniritse msinkhu uwu wa mphamvu. Chimodzi mwazinthu zofunika kwambiri pakuzindikira kuti ndi turbocharger iti yomwe ili yoyenera kwambiri ndikuganizira mphamvu zamahatchi omwe mukufuna. Koma muyenera kukhala owona pa zomwe mukuwombera.

Kugwiritsiridwa ntchito kwa galimotoyo ndi cholinga chake n'kofunika kwambiri. Mwachitsanzo, galimoto ya autocross ingafunike kukwera mwachangu kuti ifike mwachangu, pomwe galimoto ya Bonneville yomwe ikuyenda mowongoka nthawi yayitali imakhala yokhudzidwa kwambiri ndi mphamvu zamahatchi pama liwiro apamwamba kwambiri. Magalimoto a Indy nthawi zambiri amasintha ma turbo a ma track afupiafupi motsutsana ndi ma track ataliatali chifukwa chakufunika kofananira ndi ma turbo kuti akwaniritse kuthamanga kwa injini ndi magalimoto ena. Ntchito zokoka mathirakitala zitha kuwona kuthamanga kwa injini kwambiri kumayambiriro kwa mpikisano, ndipo pamene kukoka kukupitilira, katunduyo amachulukira pang'onopang'ono ngati mabuleki a prony mpaka injiniyo itatsitsidwa kwambiri ndi siloyo yokoka. Ntchito zosiyanasiyanazi zimafuna mafananidwe osiyanasiyana a turbo.

Mawu akuti Volumetric Efficiency, kapena VE, ndi liwu lofunika kwambiri komanso lingaliro loti mumvetsetse. Kukulitsa injini ya VE kumakweza mphamvu zake zamahatchi ndi RPM. Kupatulapo zosintha zamafuta ndi zoyatsira, mbali zambiri zama injini zomwe zimagwira ntchito kwambiri pambuyo pake zimakweza VE ya injiniyo. Kulowetsedwa kwa mpweya mokakamizidwa kumangowonjezera VE. Koma kodi Volumetric Efficiency kwenikweni ndi chiyani?

VE ya injini ndi kuyerekezera kwa injini yowerengera, kapena zongoyerekeza, kuchuluka kwa mpweya wa voliyumu, kuyerekeza ndi mphamvu yake yeniyeni. Injini ili ndi malo osasunthika, mwachitsanzo, mainchesi 300 kiyubiki. Kusamuka kumeneku kudzayenda pafupifupi 300 pa injini ziwiri zilizonse (injini ya sitiroko inayi iyenera kuzungulira kawiri kuti masilindala onse amalize kuzungulira zinayi). Mwachidziwitso, pangakhale mgwirizano wofananira ndi kayendedwe ka mpweya ndi injini ya RPM pomwe kuwirikiza kawiri pa mphindi kuwirikiza kawiri mpweya womwe injiniyo imachotsedwa. Ngati injini imatha kuyenda ndendende mpweya wochuluka panthawi yogwira ntchito monga momwe mawerengedwe amalingaliro amanenera kuti ndizotheka, injiniyo ikanakhala ndi VE ya 100 peresenti. Komabe, zenizeni sizichitika kawirikawiri.

Ngakhale pali injini zina zomwe zimakwaniritsa 100 peresenti kapena apamwamba VE, ambiri satero. Pali zinthu zambiri zomwe zimalepheretsa injini kuti ikwaniritse mphamvu ya 100 peresenti ya volumetric, zina mwadala, zina zosapeweka. Mwachitsanzo nyumba zotsukira mpweya ndi fyuluta zimalepheretsa kutulutsa mpweya, koma simukufuna kugwiritsa ntchito injini yanu popanda kusefera mpweya.

Chifukwa chomwe turbocharging imakhudzira kwambiri magwiridwe antchito a injini imatha kumveka bwino pogwiritsa ntchito lingaliro lamphamvu la volumetric. Mu injini ya turbocharged, nthawi imakhalabe malire kuti valavu yolowetsa imatsegulidwa nthawi yayitali bwanji, koma ngati kupanikizika kwa mpweya kuli kwakukulu kuposa kupanikizika kwa mlengalenga (kuwonjezeka), ndiye kuti tikhoza kukakamiza mpweya wochuluka kwambiri panthawi yotsegula valve. Ubwino wa mpweya umenewo umakonzedwa kuti uyake chifukwa kachulukidwe kake kawonjezedwanso. Kuphatikizika kwa kuthamanga kwamphamvu ndi kachulukidwe ka mpweya kumalipira nthawi yochepetsera nthawi ya zochitika za valve ndikulola injini zolimbikitsidwa kuti zikwaniritse bwino kuposa 100% VE. Koma mukakulitsa kuchuluka kwa mphamvu zamahatchi, ngakhale ma injini a turbocharged amapindula ndi zosintha zambiri zomwe zapangidwa kuti zipititse patsogolo VE pamainjini omwe amafunidwa mwachilengedwe.

Monga tafotokozera pamwambapa, injini yopatsidwa idzakhala ndi VE yabwinoko kapena yoyipa kuposa gulu la RPM. Injini iliyonse imakhala ndi malo ake okoma, komwe ndi komwe kumapangidwira injini komwe, pakuthamanga kwathunthu, mphamvu ya volumetric imakhala yapamwamba kwambiri. Iyi ndiye nthawi yomwe ma torque apamwamba amapezeka pamapindikira a torque. Popeza VE idzakhala pamalo apamwamba kwambiri, kugwiritsa ntchito mafuta ambiri kapena BSFC, yoyezedwa ndi mapaundi amafuta pa mphamvu ya akavalo, pa ola limodzi, idzakhalanso pachimake. Powerengera machesi oyenerera a turbo, VE ndichinthu chofunikira kuchiganizira, chifukwa ndichofunikira kwambiri pakuzindikira kufunikira kwa mpweya wa injini yomwe wapatsidwa.

ShanghaiSHOU YUANndi wodziwa zambiriwogulitsa aftermarket turbocharger ndi magawo, zomwe zidakopa makasitomala ambiri ochokera kumayiko osiyanasiyana pamsika wapadziko lonse lapansi. Pali makasitomala ambiri omwe amakhutira ndi zomwe timagulitsa ndikugulanso pafupipafupi mwezi uliwonse. Zaka 20 zathu zazaka zambiri mumakampani a turbo zitha kukupatsirani zinthu zapamwamba kwambiri komanso ntchito yosamala mukagulitsa. Tili ndi magulu osiyanasiyana azinthu, kuphatikizapogudumu la turbine, gudumu la kompresa, compressor nyumba, CHRA, etc. Choncho, mukhoza kulankhula nafe ngati mukufuna mbali iliyonse ya turbocharger.
