VVT-i
VVT-i, or Variable Valve Timing with intelligence, is an automobile variable valve timing technology developed by Toyota. It was first introduced in 1995 with the ''2JZ-GE'' engine found in the JZS155 Toyota Crown and Crown Majesta. The VVT-i system replaces the Toyota VVT system first introduced in 1991 with the five-valve per cylinder '' 4A-GE'' engine found in the AE101 Corolla Levin and Sprinter Trueno. The VVT system is a 2-stage hydraulically controlled cam phasing system. VVT-i varies the timing of the intake valves by adjusting the relationship between the camshaft drive (belt or chain) and intake camshaft. Engine oil pressure is applied to an actuator to adjust the camshaft position. Adjustments in the overlap time between the exhaust valve closing and intake valve opening result in improved engine efficiency. Variants of the system, including VVTL-i, Dual VVT-i, VVT-iE, VVT-iW and Valvematic, have followed. VVTL-i VVTL-i (Variable Valve Timing and Lift intellig ...

Toyota ZZ Engine
The Toyota ZZ engine family is a straight-4 piston engine series. The ZZ series uses a die-cast aluminium engine block with thin press-fit cast iron cylinder liners, and aluminium DOHC 4-valve cylinder heads. The camshafts are chain-driven. The two 1.8 L members of the family, the 1ZZ and 2ZZ, use different bore and stroke. The former was optimised for economy, with torque emphasised in lower revolutions per minute operating range, while the latter is a "square" design optimised for high-RPM torque, yielding higher peak power. The ZZ family replaced the extremely popular cast-iron block '' 4A'' engines. Toyota engine names are interpreted as follows. The leading number denotes the generation, and the next one or two letters, specify the engine family. The remaining letters, following a hyphen, describe the engine's major features. For example, the 2ZZ-GE can be decoded as being the second generation of the ZZ engine series and features a performance-oriented cylinder head wi ...

Toyota Celica
The is an automobile produced by Toyota from 1970 until 2006. The Celica name derives from the Latin word '' coelica'' meaning 'heavenly' or 'celestial'. In Japan, the Celica was exclusive to the ''Toyota Corolla Store'' dealer chain. Produced across seven generations, the Celica was powered by various four-cylinder engines, and bodystyles included convertibles, liftbacks, coupés and notchback coupés. In 1973, Toyota coined the term ''Liftback'' to describe the Celica fastback hatchback, and used the name ''Liftback GT'' for the North American market. Like the Ford Mustang, the Celica concept was to create a sports car by attaching a coupe body to the chassis and mechanicals from a high volume sedan, in this case the Toyota Carina. However, some journalists thought it was based on the Corona due to some shared mechanical parts. The first three generations of North American market Celicas were powered by variants of Toyota's R series engine. In August 1985, the car's ...

Variable Valve Timing
In internal combustion engines, variable valve timing (VVT) is the process of altering the timing of a valve lift event, and is often used to improve performance, fuel economy or emissions. It is increasingly being used in combination with variable valve lift systems. There are many ways in which this can be achieved, ranging from mechanical devices to electro-hydraulic and camless systems. Increasingly strict emissions regulations are causing many automotive manufacturers to use VVT systems. Two-stroke engines use a power valve system to get similar results to VVT. Background theory The valves within an internal combustion engine are used to control the flow of the intake and exhaust gases into and out of the combustion chamber. The timing, duration and lift of these valve events has a significant impact on engine performance. Without variable valve timing or variable valve lift, the valve timing is the same for all engine speeds and conditions, therefore compromises are neces ...

Toyota Avalon
The is a full-size sedan produced by Toyota. It is Toyota's largest front-wheel drive sedan and serves as its flagship vehicle in the United States, Canada, China and the Middle East. It was also produced in Australia from April 2000 until June 2005, when it was replaced in November 2006 by the Aurion. The first production Avalon rolled off the TMMK assembly line in Georgetown, Kentucky, in September 1994, and subsequent generations have all been manufactured at the Kentucky location to date. Toyota marketed the Avalon as a replacement for the Cressida, a model discontinued for the American market in 1992. While the Cressida was an upper-level mid-size rear-wheel drive car with a straight-six engine, the Avalon is front-wheel drive, powered by a V6 engine. In recent years, there has been considerable overlapping with its platform mates, the Camry V6 and the Lexus ES, although the third-generation and subsequent Avalon was distinguished by offering extra legroom due to its ext ...
