VVT-iW
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 improved engine ...

Toyota Celica (T230)
The is an automobile produced by Toyota from 1970 until 2006. The Celica name derives from the Latin word ''wikt:coelicus, coelica'' meaning ''heavenly'' or ''celestial''. 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 ...

Direct Fuel Injection
Fuel injection is the introduction of fuel in an internal combustion engine, most commonly automotive engines, by the means of a fuel injector. This article focuses on fuel injection in reciprocating piston and Wankel rotary engines. All compression-ignition engines (e.g. diesel engines), and many spark-ignition engines (i.e. petrol (gasoline) engines, such as Otto or Wankel), use fuel injection of one kind or another. Mass-produced diesel engines for passenger cars (such as the Mercedes-Benz OM 138) became available in the late 1930s and early 1940s, being the first fuel-injected engines for passenger car use. In passenger car petrol engines, fuel injection was introduced in the early 1950s and gradually gained prevalence until it had largely replaced carburetors by the early 1990s. The primary difference between carburetion and fuel injection is that fuel injection atomizes the fuel through a small nozzle under high pressure, while carburetion relies on suction created b ...

Camshaft
A camshaft is a shaft that contains a row of pointed cams in order to convert rotational motion to reciprocating motion. Camshafts are used in piston engines (to operate the intake and exhaust valves), mechanically controlled ignition systems and early electric motor speed controllers. Camshafts in piston engines are usually made from steel or cast iron, and the shape of the cams greatly affects the engine's characteristics. History Trip hammers are one of the early uses of a form of cam to convert rotating motion, e.g. from a waterwheel, into the reciprocating motion of a hammer used in forging or to pound grain. Evidence for these exists back to the Han dynasty in China, and they were widespread by the medieval period. Camshafts were first described by Ismail al-Jazari in 1206. Once the rotative version of the steam engine was developed in the late 18th century, the operation of the valve gear was usually by an eccentric, which turned the rotation of the crankshaft i ...

Poppet Valve
A poppet valve (also sometimes called mushroom valve) is a valve typically used to control the timing and quantity of petrol (gas) or vapour flow into or out of an engine, but with many other applications. It consists of a hole or open-ended chamber, usually round or oval in cross-section, and a plug, usually a disk shape on the end of a shaft known as a valve stem. The working end of this plug, the valve face, is typically ground at a 45° bevel to seal against a corresponding valve seat ground into the rim of the chamber being sealed. The shaft travels through a valve guide to maintain its alignment. A pressure differential on either side of the valve can assist or impair its performance. In exhaust applications higher pressure against the valve helps to seal it, and in intake applications lower pressure helps open it. Etymology The word poppet shares etymology with "puppet": it is from the Middle English ''popet'' ("youth" or "doll"), from Middle French ''poupette'', whic ...

Intake
An intake (also inlet) is an opening, structure or system through which a fluid is admitted to a space or machine as a consequence of a pressure differential between the outside and the inside. The pressure difference may be generated on the inside by a mechanism, or on the outside by ram pressure or hydrostatic pressure. Flow rate through the intake depends on pressure difference, fluid properties, and intake geometry. Intake refers to an opening, or area, together with its defining edge profile which has an associated entry loss, that captures pipe flow from a reservoir or storage tank. Intake refers to the capture area definition and attached ducting to an aircraft gas turbine engine or ramjet engine and, as such, an intake is followed by a compressor or combustion chamber. It may instead be referred to as a diffuser (other), diffuser. For an automobile engine the components through which the air flows to the engine cylinders, are collectively known as an intake syste ...

Toyota A Engine
The Toyota A Series engines are a family of inline-four internal combustion engines with displacement from 1.3 L to 1.8 L produced by Toyota Motor Corporation. The series has cast iron engine blocks and aluminum cylinder heads. To make the engine as short as possible, the cylinders are siamesed. The development of the series began in the late 1970s, when Toyota wanted to develop a completely new engine for the Toyota Tercel, the successor of Toyota's K engine. The goal was to achieve good fuel efficiency and performance as well as low emissions with a modern design. The A-series includes one of the first Japanese mass-production DOHC, four-valve-per-cylinder engines, the 4A-GE, and a later version of the same engine was one of the first production five-valve-per-cylinder engines. Toyota joint venture partner Tianjin FAW Xiali produces the 1.3 L 8A and resumed production of the 5A in 2007. 1A The 1.5 L 1A was produced between 1978 and ...
