The Dual VVT-i system adjusts timing on both intake and exhaust camshafts. It was introduced in 1998 on the RS200 Altezza's 3S-GE engine. Dual VVT-i is also found in Toyota's 3.5-litre 2GR-FE V6 engine, first appearing on the 2005 Avalon. This engine can be found on numerous Toyota and Lexus models.
Replacement of UZ (2006-) - engines for top FR (Crown, GS, LS) and heavy SUVs (LC 200, Sequoia), made in the modern tradition with aluminium block, DVVT and with D-4 versions. 1UR-FSE - - the basic engine of the series, for passenger cars, with combined injection (D-4S) and electric drive for intake variable valve timing (VVT-iE) VVT-i, or Variable Valve Timing with intelligence, is an automobile variable valve timing technology developed by Toyota.VVT-i, introduced in 1996. It varies the timing of the intake valves by adjusting the relationship between the camshaft drive (belt, scissor-gear or chain) and intake camshaft. Engine oil pressure is applied to an actuator to Saat ini, mesin Toyota sudah menggunakan teknologi katup variabel yang diberi nama Dual VVT-i. Berikut fakta menarik mengenai teknologi ini. 1. Arti Nama VVT-i. Nama VVT-i merupakan singkatan dari Variable Valve Timing with Intelligence dan merupakan teknologi awal katup variabel yang dikembangkan oleh Toyota. The 2ZZ-GE used VVTL-i (Intelligent variable valve timing with lift). To variable inlet valve timing, the 2ZZ-GE engine used a variable valve lift system operated on the inlet and exhaust valves. At engine speeds above 6000 rpm, high-lift camshaft profiles are engaged and the cam lobes increased intake lift from 7.25 to 11.2 mm and exhaust lift Grand New Avanza dan Grand New Veloz menggunakan mesin berteknologi Dual VVT-i (variable valve timing with intelligence) dengan kapasitas 1.300 cc dan 1.500 cc. Teknologi Dual VVT-i ini diklaim memiliki cara kerja pintar yang mampu membuat mesin lebih efisien dan ramah lingkungan. Teknologi Dual VVT-i ini memungkinkan tenaga yang tersalurDual VVT-i technology controls the opening and closing timing of the intake and exhaust valves to enhance engine performance and efficiency. At low speeds, this technology optimizes engine torque for better acceleration, while at high speeds, it increases engine power for maximum speed.
