Nakuba iningi lezingxoxo zezimoto ezintsha kulezi zinsuku ligxile ekuqedeni izinjini zokushisa zangaphakathi zama-EV asebenza ngebhethri, kusekhona amanye ama-OEM afuna ukwanelisa izifiso zabathandi bezinjini zethu. Isibonelo esiphelele yinjini entsha ye-Chevrolet Performance i-ZZ632/1000 enkulu – amandla angaphezu kuka-1,000 horsepower kanye nokusetshenziswa kukaphethiloli okungama-cubic inches angu-632!
Siyazi ukuthi izinjini zama-crate zingaba yindaba ethinta inhliziyo kubantu bethu, kodwa kunzima ukungazinaki lokho okwenziwa amanye ama-OEM muva nje. Nakuba lokho kungase kubonakale kuphikisana nazo zonke izithembiso zokuthuthela ezimotweni ezixubile nezikagesi, izinkampani zezimoto ezifana neDodge neChevrolet nazo ziyakhuphula izinga lokushisa kwangaphakathi, ngemikhiqizo efana neHellephant kanye ne-572 big block ku-COPO Camaro.
I-Chevrolet Performance manje isiyithatha igxathu eliya phambili nge-Chevrolet yayo yakamuva enkulu engu-632-cubic-inch, engu-10.35-litre, enamandla amahhashi angu-1,004. Le njini yaboniswa ku-SEMA 2021, futhi izinjini zekhreyithi ezinjengalezi ziyaqhubeka nokukhula ngobuchwepheshe obuningi, amandla amaningi, kanye nokuguquguquka okukhulu kunanini ngaphambili.
Injini entsha yeChevrolet Performance ZZ632/1000 Deluxe Big Block Crate Engine nayo ayihlukile. Iyinjini ye-crate enamandla kakhulu eyake yakhiwa yiChevrolet, enobuchwepheshe besimanje be-EFI kanye namandla angaphezu kuka-1,000 e-horsepower kugesi we-93-octane pump. Ifinyelela kulawo mandla e-horsepower ku-6,600 rpm futhi inikeza i-torque engu-876 lb.-ft. ku-5,600 rpm. Sishilo yini ukuthi lezi zinombolo ziphefumula ngokwemvelo?
I-ZZ632 iyinjini ye-V8 enensimbi ephothiwe, amabhlogo amade edekhi anezimbozo zamandla ezingama-4-bolt, imbobo engu-4.600˝ x 4.750˝ kanye ne-stroke. Iyisisekelo esifanayo esisetshenziswe kubhlokhi engu-572, kodwa ibholiwe ngaphezu kuka-0.040˝ futhi inokuhamba okungaphezulu okungu-3/8″. Inhlanganisela ejikelezayo iqukethe i-crankshaft yensimbi engu-4340 eyakhiwe, izinduku ze-H-beam zensimbi eyenziwe kanye nama-piston e-aluminium angu-2618 akhiwe, konke okulinganiselayo ngaphakathi.
Ngaphezulu, i-632 inekhanda lesilinda le-aluminium expansion port elinegumbi elingu-70cc kanye nomklamo we-RS-X. I-intake manifold nayo iyi-aluminium futhi iyidizayini ephakeme, enendiza eyodwa. Isitimela se-valve sakhiwe yi-billet steel hydraulic roller camshaft enobude bokungenisa obungu-270º kanye nobude bokukhipha obungu-287º. Ukuphakamisa ama-valve kungu-0.780˝ intake kanye no-0.782˝ intake.
Uma sikhuluma ngama-valve, izingxenye ziyi-titanium ene-port yokungenisa engu-2.450-intshi, i-port yokukhipha engu-1.800-intshi, kanye nesiqu esingu-5/16 OD. I-swingarm iyi-swingarm eyenziwe nge-aluminium roller shaft enesilinganiso esingu-1.8:1.
Ezinye izici zenjini zifaka phakathi ama-86 lb/hr. Ama-fuel injector, i-58X crank trigger, i-coil near-plug ignition, i-aluminium water pump, i-8-qt steel sump kanye ne-throttle body yesitayela esingu-4500. Konke lokhu kunikeza amandla angaphezu kuka-1,000 horsepower ku-93-octane kanye ne-12:1 compression ratio ku-7,000 rpm.
Njengoba kunokusekelwa okuningi kwe-aftermarket kwe-big block, akunzima ngabantu ukusunduza le njini idlule uphawu lwamandla amahhashi ayi-1,004, kungakhathaliseki ukuthi ukhetha ukusebenzisa i-induction ephoqelelwe noma cha. Njengoba cishe amalitha ayi-10.4 okufuduka atholakala kanye nengxenye engezansi eyakhiwe ngokuphelele, le njini isilungele ukuthwala isijeziso samandla amahhashi aphezulu.
Ngakho-ke, kunezinhlebezi eziningi mayelana nentengo yenjini enamandla amahhashi ayi-1,000, engama-cubic-intshi angu-632. I-MSRP yeChevrolet ibukeka iphakathi kuka-$37K-$38K. Uma ungaphila ngentengo, singathanda ukwazi ukuthi ulungele ukufaka lesi silo kuphi. Sizotholakala ekuqaleni kuka-2022.
Injini yaleli sonto ixhaswe yiPennGrade Motor Oil, i-Elring – Das Original kanye ne-Scat Crankshafts. Uma unenjini ongathanda ukuyigqamisa kulolu chungechunge, sicela uthumele i-imeyili ku-Editor Engine Builder Editor uGreg Jones [email protected]
