Injini iToyota Lexus 2UZ-FE 4.7 V8

Injini engu-8-cylinder 2UZ-FE (Toyota / Lexus) enomthamo wamalitha angu-4,7 yakhishwa ngo-1998 embonini eyayise-USA, e-Alabama. Ama-motor cylinders enziwe nge-cast iron futhi anohlelo olumiswe njengo-V. Uhlelo lokujova uphethiloli luyi-elektroniki, lunamaphuzu amaningi. Imodeli yakhelwe ukuthwebula kanye namaSUV amakhulu, ngakho-ke ine-torque ephezulu (434 N * m) kuma-revs amaphakathi. Amandla amakhulu enjini angama-288 "amahhashi", kanti isilinganiso sokuminyaniswa ngu-9,6.

Ukuguqulwa

Ngo-2011, umkhiqizi wakhipha inguqulo ebuyekeziwe yenjini engu-2UZ-FE, ifakwe i-valve mpintsha kagesi kanye nohlelo lwe-VVT-i oluguquguqukayo lwesikhathi. Lokhu kwenza ukuthi kutholakale amandla ka-288 litres. sec., okungamayunithi angama-50 ngaphezulu kunenguqulo yakudala, futhi akhuphule i-torque ibe ngu-477 N * m.

Izinkinga ze-2UZ-FE

Le divayisi ayinazithiyo ezinkulu, ngokulungiswa okufika ngesikhathi kwemoto nokusetshenziswa kwezinto ezisezingeni eliphezulu ze-2UZ-FE akulethi zinkinga kumthandi wemoto. Noma kunjalo, injini isenamaphuzu abuthakathaka. Lokhu:

• phezulu ukusetshenziswa kukaphethiloli;
• isidingo sokulawulwa njalo kokuvuleka kwama-valve;
• ingozi yokwephuka kwe-hydraulic tensioner ngenkathi kushintshwa ibhande;
• insiza encane yempompo yamanzi nebhande lesikhathi (idinga ukushintshwa njalo ngamakhilomitha angama-80 - 000).

Iphi inombolo yenjini

Inombolo yedivayisi itholakala ngaphambili, ekuweni kwebhlokhi.

Ukushuna 2UZ-FE

Enye yezindlela ezilula zokwengeza amandla we-2UZ-FE ukuthenga nokufaka i-compressor kusuka ku-TRD. Lokhu kuzokhulisa amandla afike ku-350 hp.

Enye indlela ukusebenzisa ipompo yeWalbro, ama-piston awumbumbulu, ama-injektha amasha, izikopelo ze-ARP kanye ne-3-intshi exhaust. Le ndlela izosiza ukuthuthukisa amandla afinyelela kumalitha angama-400. nge.

Yimaphi amamodeli afakiwe

I-2UZ-FE motor ifakiwe kumikhiqizo yezimoto enjenge:

• I-Lexus GX 470;
• I-Lexus LX 470;
• IToyota Tundra;
• IToyota 4Runner;
• IToyota Sequoia;
• IToyota Land Cruiser.

Ngokusho kokubuyekezwa kwabanikazi bezimoto kanye ne-auto mechanics, insiza yenjini ye-2UZ-FE ifinyelela cishe amakhilomitha ayisigidi, futhi phesheya, njengomthetho, abashayeli bashintsha izimoto njalo eminyakeni engu-1-4. Ngenxa yalesi sizathu, lesi simodeli sifunwa kakhulu emakethe yesibili ye-Russian Federation. Abathandi bezimoto abaningi baseRussia bakhombisa ukuyithakasela injini ye-5UZ-FE bese beyifaka ezimotweni ukubanika "impilo yesibili".
