Kuti awedzere simba rebhiza uye kutamiswa kweCorvette ZR-1 yake, Phil Wasinger akatanga kugadzira injini yake paakawana injini yakashandiswa yeLT5 paCraigslist muna 2014. Tarisa uone zvakaitika kuchirongwa chemakore matanhatu ichi.
Nekuda kweiyo yakasarudzika dhizaini uye kushomeka kwekugadzirwa kwe1990-1995 ZR-1 Corvettes, injini yeLT5 yaishuvira haina kunakidzwa nekuita kwaita seChevrolet, Chrysler uye mamwe mainjini eFord akagadzirwa. Zvisinei, izvi hazvina kuzvimisa. Phil Wasinger akavakazve injini yake yeLT5 mune yake 1994 ZR-1 Corvette.
Chinangwa chikuru cheinjini yeLT5 chaive chekuti Lotus Engineering (yaive naGM panguva iyoyo) yakagadzira iyo LT5, GM yakasimbirira kuti vashandise cylinder hole spacing, cylinder block deck kureba, uye crankshaft main bearing gole dhayamita seSB Chevy, kunyangwe zvikasadaro, Iyo yakasiyana zvachose injini dhizaini, kunze kweiyo crankshaft rear oiri chisimbiso, hapana zvikamu zvakajairika pakati pavo. Paunenge uchisiya fekitori, iyo LT5 cylinder block inotora yakavhurika dhizaini dhizaini, uye yepasi silinda block inodhiriwa kuti igare iyo 4.173 OD nhanho aluminium lining.
Kuvakazve injini yaWasinger kwakatanga muna 2014, paakawana injini yakashandiswa yeLT5 paCraigslist.
"Ndakatenga yangu 1994 Corvette ZR-1 muna 2007 uye ndakakwidziridza injini neyakajairwa mabhoti-on magadzirirwo anoenderana neidzi injini dzakasiyana," akadaro Wasinger. “Izvi zvinosanganisira misoro yemapombi marefu, kuita kwekatback exhaust, kutora pachiteshi, uye kuita tuning machipisi. Kuma350 cid, akawanda mastock engines anomhanya zvakanaka, anoburitsa anenge mazana mana nemakumi masere nemashanu emabhiza, uye nyore kutendeukira ku7,200 rpm. Nekudaro, ini ndinoda chaizvo Kuona izvo iyo DOHC LT5 dhizaini inogona kuita nekuwedzera kutamiswa, misoro yemasilinda, uye tsika dzekuita kamera. Izvi zvakatanga rwendo rwangu rwemakore matanhatu epic ye427 cid LT5.
Panyaya yekugadzira injini, Phil haisi yakajairwa DIYer. Kweakawanda ebasa rake, akashandira makuru eGerman anogadzira injini yedhiziri MTU Friedrichshafen uye MAN Augsburg, vachitungamira mashandiro avo muUnited States. VeUS Navy, veUS Coast Guard neAmerican Flag Commercial Shipping Company ndivo vatengi vake vakuru.
Nekudaro, kusiyana nebasa raakaita mubasa rake, iyi LT5 kuvaka ibasa rekuzvivaraidza, rinonyanya kuitwa mugaraji remhuri yaPhil. Basa remuchina uye chiyero chakaitwa muwekishopu yekugadzira injini yemunharaunda padyo neguta rake rekuFairfax, Virginia, kuchamhembe kweVirginia. Chekutanga pane zvese, Phil aiziva kuti aida simba rakawanda rebhiza uye kutamiswa.
"Chinangwa chedu ndechekupa yakatsetseka uye yakavimbika 650 horsepower yemugwagwa uye cruising," akadaro Vasinger. "Nekuda kweiyo yakasarudzika dhizaini yeLT5, sitiroko crankshaft inofanirwa kugadzirwa kubva pasina. Iyo crankshaft ine nhamba yakakura yezvibhorani zvemukati seyo chete nzira yekugovera mafuta kune iyo huru inotakura uye yekubatanidza tsvimbo inotakura. Sezvineiwo, ndaibva kune mumwe munhu kuTexas Murume uyu akawana simbi isina kushandiswa 4.00˝ crankshaft. Pakutanga akaitenga yeLT5 vhezheni, asi akatadza kuzviziva.
“Kuti mushandise 4.000˝ stroke crankshaft kusvika painongedzerwa 427 cid, cylinder bore inofanira kuwedzerwa kubva pa3.900˝ kusvika pa4.125˝, izvo zvinoda kuti humburumbira inogamuchira chibhorani chiwedzerwe. Nekuda kweizvi, ndakatendeukira kuna Pete Polatsidis, nyanzvi yeinjini yeLT5 muChicago, Akagadzira dhizaini yakavharwa ductile iron bushing conversion uye Darton Sleeves yeLT5 injini.
Iyo LT5 silinda block yakagadzirirwa kushandisa 99mm aluminium bushings uye mapiston anogadzirwa naMAHLE. Iyo yemukati yekumusoro ye lining yakashongedzwa neNikasil kuti ipe yakasimba kwazvo kupfeka-inodzivirira nzvimbo. Iyo gadziriso ndeye yakavhurika dhizaini dhizaini ine chikamu chepasi cheiyo liner inotsvedza yakaiswa mugomba rekugamuchira rakagadzirwa kusvika pazasi pe block.
Kuti uwane 4.125˝ gomba raidiwa naPhil, zvaive zvakafanira kushandisa yakanyatsogadziriswa ductile iron lining yakatanga kubudiswa neDarton Sleeves uye yakagadziridzwa naPete Polatsidis kushandisa dhizaini yakavharwa.
"Neiyi yakavharwa dhizaini, iyo cylinder yemukati dhayamita inogona yakachengeteka yakawedzera kusvika 4.125˝, uye imwe bhenefiti ndeyokuti yakanyanya kugadzikana muhumburumbira," akadaro.
Mushure mekunzwisisa crankshaft uye kutamiswa kweinjini, Phil akatendeudzira pfungwa dzake kune zvimwe zvinhu zvemukati, senge 6-inch billet yekubatanidza tsvimbo imwe neimwe inorema 605 magiramu, akabatanidzwa netsika Diamond akagadzira aluminium pistons ane siketi coatings uye offset pini.
"Piston ine compression reshiyo ye12: 1, uye pini yekumisa uye siketi coating yakanyatsogadzirirwa kuderedza kutonhora-kutanga kwepiston ruzha," Wasinger akadaro. "Ini zvakare ndakashandisa Total Seal piston mhete-ine 1.5mm inogoneka molybdenum mhete yepamusoro, 1.5mm inogoneka koni yakamonwa mhete yechipiri, uye 3mm yekudzora mafuta mhete."
Iyo LT5 vhezheni yakagamuchirawo Calico coated bearings-OEM pane chikuru magetsi uye 2.1˝ yakanamirwa Clevite 77 mabhengi padanda. Iyo yejenari clearance pakati peiyo tsvimbo inotakura uye huru inotakura yakaiswa pa 0.0025˝.
Kana zvasvika kune misoro yemasilinda uye zvitima zvevharuvhu, Phil akataura kuti LT5 ina-vharuvhu yemusoro inopisa kamuri yakagadzirirwa kuve yakanyanya anti-kugogodza, ichibvumira yakakwira compression ratios kuti ishandiswe pakupomba mweya. Kuti awedzere kuseta kwake, musoro wecylinder wakasimwa zvachose uye kuyerera kwakaedzwa. Iyo mhepo inopinza inovhurwa kusvika 37 mm, uye mhepo yekupinza mbiya inowedzerwawo.
“Ivharuvhu yekutanga ye39mm yakatsiviwa nevharuvhu yeFerrea ye42mm Stainless steel ine hunde ye8mm,” akadaro. “Itake valve seat yakawedzerwawo kuti ishandise zvizere vharafu hombe yekupinda nayo. Ndakashandisawo zvitubu zveFerrea uye zvinochengeta. "
Kuti aite kuti mavharuvhu ashande nemazvo, Wasinger akasarudza tsika billet camshaft kubva kuJones Cam Design. Pamusoro pebasa rake, Phil akataura kuti kutenderera kwechikamu kuyera uye tsika silinda musoro valve basa rakaitwa munharaunda naLloyd Lovelace weCustom Automotive Machine muLorton, Virginia. Yekupedzisira yemotokari dynamometer tuning yakaitwa neHaibeck Automotive Technology muAddison, Illinois.
Mushure mekunge LT5 yanyatsounganidzwa uye kugadziridzwa, Wasinger akati akawana mazana matanhatu nemakumi mashanu emabhiza aaitarisira. Zvino, iyi 1994 ZR-1 Corvette yadzoka mumugwagwa.
Svondo rino injini iyi yakatsigirwa nevePennGrade Motor Oil, Elring – Das Original neScat Crankshafts. Kana iwe uine injini yaunoda kuratidza mune ino nhevedzano, ndapota tumira email kune [email yakachengetedzwa] Injini Inovaka mupepeti Greg Jones
