Cutaway view of Variable Valve Timing with intelligence on a ZR engine in Techniquest Glyndŵr. VVT-i, or Variable Valve Timing with intelligence, is an automobile variable valve timing petrol engine technology manufactured by Toyota Group and used by brands Groupe PSA (Peugeot and Citroen), Toyota, Lexus, Scion, Daihatsu, Subaru, Aston Martin, Pontiac and Lotus Cars.
Early variable valve timing systems used discrete (stepped) adjustment. For example, one timing would be used below 3500 rpm and another used above 3500 rpm. More advanced variable valve timing systems offer continuous (infinite) adjustment of the valve timing. Therefore, the timing can be optimized to suit all engine speeds and conditions. [2] [3]
VVT-i variable valve timing was added in 1995, for an output of 147 kW (197 bhp; 200 PS) at 6000 rpm and 251 N⋅m (185 lb⋅ft) at 4000 rpm. The exterior design of the 1JZ-GE would later be reused with the 2JZ-GE in 1991, which shared most of its parts with the 1JZ-GE. The non-turbo, non-VVT-i 1JZ-GE is a non-interference engine.
It features DOHC, 16 valves and VVT-i. Bore and stroke is 86 mm × 86 mm (3.39 in × 3.39 in). Its power is 100 kW (134 hp; 136 PS) at 5,600 rpm, and 18.6 kg⋅m (182 N⋅m; 135 lbf⋅ft) of torque at 4,000 rpm with redline of 6000 rpm. Just like its sister, the 2TR-FE engine, the 1TR-FE engine also received a Dual VVT-i update. The updated ...
The Toyota 4ZR-FE is a 1.6 L (1,598 cc) DOHC, 16-valve engine with Dual VVT-i. Output for this engine is rated at 117 hp (87 kW; 119 PS) at 6000 rpm and 150 N⋅m (111 lb⋅ft) of torque at 4400 rpm. It is an analogue of the 1ZR-FE for use in China only. Applications. Toyota Corolla EX (ZRE120) (China only) Toyota Yaris (ZSP91) (China only)
The engine series shares many of the technologies in the AZ engine, while incorporating features such as variable valve timing on both intake and exhaust camshafts or dual VVT-i, low friction technologies including an offset crankshaft, roller rockers for the valvetrain, a three-stage variable oil pump, reduced-tension piston rings and ...
The engine was slightly revised in 1995 with lighter connecting rods and pistons and an increased compression ratio to 10.4:1 resulting in peak power of 195 kW (261 hp; 265 PS) at 5,400 rpm and torque of 365 N⋅m (269 lb⋅ft) at 4,400 rpm. In 1997, Toyota's VVT-i variable valve timing technology was introduced along with a further compression ...
The first version was equipped with VVT-i and produced 200 PS (147 kW; 197 hp) at 7,000 rpm when coupled to a manual transmission. The automatic version produced 190 PS (140 kW; 187 bhp) at 7000 rpm; this is believed to be an ECU restriction implemented by Toyota due to gearbox limitations.
