VVT-i
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. It was 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 introduced in 1991 with the five-valve per cylinder '' 4A-GE'' "Silver Top" engine found in the AE101 Corolla Levin and Sprinter Trueno. The previous VVT system was 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 impr ...

In Japan, the Celica was exclusive to ''Toyota Corolla Store'' Car dealership, dealer Chain store, chain. Produced across seven generations, the Celica was powered by various four-cylinder engines, and body styles included convertible (car), convertibles, liftbacks, and notchback coupé. In 1973, Toyota coined the term ''liftback'' to describe the Celica fastback hatchback, and the GT Liftback would be introduced for the 1976 model year in North America. Like the Ford Mustang, the Celica concept was to attach a coupe body to the chassis and mechanicals from a high volume sedan, in this case the Toyota Carina. The first three generations of North American market Celicas were powered by variants of Toyota's Toyota R engine, R series engine. In August 1985, the car's drive layout was changed from rear-wheel driv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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, aluminium DOHC 4-valve cylinder heads, and chain-driven camshafts. The ZZ family replaced the extremely popular cast-iron block '' 4A'' and '' 7A'' engines of the preceding '' A'' family of engines. 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. Model code breakdown 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 ...

Variable Valve Timing
Variable valve timing (VVT) is the process of altering the timing of a Poppet valve, valve lift event in an internal combustion engine, 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 cycle, Two-stroke engines use a Two-stroke power valve system, 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 (variable valve lift), the valve timing is the same for all ...

Automobile
A car, or an automobile, is a motor vehicle with wheels. Most definitions of cars state that they run primarily on roads, Car seat, seat one to eight people, have four wheels, and mainly transport private transport#Personal transport, people rather than cargo. There are around one billion cars in use worldwide. The French inventor Nicolas-Joseph Cugnot built the first steam-powered road vehicle in 1769, while the Swiss inventor François Isaac de Rivaz designed and constructed the first internal combustion-powered automobile in 1808. The modern car—a practical, marketable automobile for everyday use—was invented in 1886, when the German inventor Carl Benz patented his Benz Patent-Motorwagen. Commercial cars became widely available during the 20th century. The 1901 Oldsmobile Curved Dash and the 1908 Ford Model T, both American cars, are widely considered the first mass-produced and mass-affordable cars, respectively. Cars were rapidly adopted in the US, where they replac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
