Ford I4 DOHC Engine
The Ford I4 DOHC engine is a cast iron block 4-cylinder inline internal combustion engine with twin overhead camshafts, produced by the Ford Motor Company at Dagenham Engine Plant. It was initially available as a 2.0 litre 8-valve version, and later in 2.0 and 2.3 litre 16-valve versions from 1989 to the end of production of the MK2 Ford Galaxy in 2006. It powered various Ford models during this time, but was most well known in the rear-wheel drive "Twin Cam" variants of the Ford Sierra and Ford Scorpio. Despite being built for the company's larger RWD models, Ford also employed the engine in the front-wheel drive Galaxy and the Escort RS 2000 16v. History The engine was originally designed to replace the 2.0 L OHC Pinto engine, derivatives of which had powered most of Ford's four-cylinder rear-wheel drive cars since the early 1970s, and which was by that time lagging behind the competition in terms of power output, efficiency and refinement. Equipped with a new ...

Ford Pinto Engine
The Ford Pinto engine was the unofficial name for a four-cylinder internal combustion engine built by Ford Europe. In Ford sales literature, it was referred to as the EAO or OHC engine and because it was designed to the metric system, it was sometimes called the "metric engine". The internal Ford codename for the unit was the T88-series engine. European Ford service literature refers to it as the Taunus In-Line engine (hence the TL codenames). In North America it was known as the Lima In-Line (LL), or simply the Lima engine due to its being manufactured at Lima Engine in Lima, Ohio. It was used in many European Ford cars and was exported to the United States to be used in the Ford Pinto, a successful subcompact car of the 1970s, hence the name which is used most often for the unit. In Britain, it is commonly used in many kit cars and hot rods, especially in the 2-litre size. Pinto OHC (TL) In Europe, the Pinto OHC was introduced in 1970 to replace the Essex V4 used in the Cors ...

Crankshaft
A crankshaft is a mechanical component used in a piston engine to convert the reciprocating motion into rotational motion. The crankshaft is a rotating shaft containing one or more crankpins, that are driven by the pistons via the connecting rods. The crankpins are also called ''rod bearing journals'', and they rotate within the "big end" of the connecting rods. Most modern crankshafts are located in the engine block. They are made from steel or cast iron, using either a forging, casting or machining process. Design The crankshaft located within the engine block, held in place via main bearings which allow the crankshaft to rotate within the block. The up-down motion of each piston is transferred to the crankshaft via connecting rods. A flywheel is often attached to one end of the crankshaft, in order to smoothen the power delivery and reduce vibration. A crankshaft is subjected to enormous stresses, in some cases more than per cylinder. Crankshafts for single-cylin ...

Timing Belt (camshaft)
In a piston engine, either a timing belt (also called a ''cambelt'') or timing chain or set of timing gears is used to synchronize the rotation of the crankshaft and the camshaft. This synchronisation ensures that the engine's valves open and close at the correct times in relation to the position of the pistons. Design In most piston engines, the camshaft(s) are mechanically connected to the crankshaft. The crankshaft drives the camshaft (via a timing belt, timing chain or pushrods), which in turn actuates the intake and exhaust valves. These valves allow the engine to inhale air (or an air/fuel mixture) and exhale the exhaust gasses. The most common devices to transfer the drive are toothed rubber belts, metal timing chains or a set of gears. The teeth of the belt/chain/gears mesh with both the crankshaft and camshaft(s), thereby synchronising their motion. In many older overhead valve engines, the camshaft is located in the block near the crankshaft, therefore a simple gear ...

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. The camshaft was described in 1206 by engineer Al-Jazari. He employed it as part of his automata, water-raising machines, and water clocks such as the castle clock. Once the rotative version of the steam engine was developed in the late 18th century, the ...

Valve Lifter
A tappet is most commonly a component in an internal combustion engine which converts the rotating motion of the camshaft into linear motion of the valves, either directly or indirectly. An earlier use of the term was for part of the valve gear in beam engines beginning in 1715. The term is also used for components in pneumatic cylinders and loom, weaving loom. __TOC__ Beam engines The first recorded use of the term tappet is as part of the valve gear in the 1715 Newcomen atmospheric engine, Newcomen engine, an early form of steam engine. Early versions of the Newcomen engines from 1712 had manually operated valves, but by 1715 this repetitive task had been automated through the use of tappets. The beam of the engine had a vertical 'plug rod' hung from it, alongside the cylinder. Adjustable blocks or 'tappets' were attached to this rod and as the beam moved up and down, the tappets pressed against long levers or 'horns' attached to the engine's valves, working the cycle of ...

Poppet Valve
A poppet valve (also called mushroom valve) is a valve typically used to control the timing and quantity of gas or vapor flow into an engine. 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. The poppet valve was invented in 1833 by American E.A.G. Young of the New Castle and Frenchtown Turnpike and Railroad Company, Newcastle and Frenchtown Railroad. Young had patented his idea, but the 1836 U.S. Patent Offic ...

Zetec
Ford Motor Company used the Zetec name on a variety of inline 4-cylinder automobile engines. It was coined to replace "Zeta" on a range of 1.6 L to 2.0 L multi-valve engines introduced in 1991 because Ford was threatened with legal action by Lancia who owned the Zeta trademark. The company used the name widely in European advertising and later introduced it to the North American market with the Contour. The Zetec name was so recognized that Ford decided to apply it to other high-tech four-cylinder engines. It is used across many engine types in Europe today even though the original Zeta design ended production in 2004. Ford also used the "Zetec" name for a trim level designation in certain markets. A Formula One engine was produced for Ford by Cosworth in 1993. The Ford-Cosworth EC / ED engine, 3.5-litre Zetec R V8 engine, V8 was used by the Benetton Formula, Benetton team in 1994, and powered Michael Schumacher to his first List of Formula One World Drivers' Champions, ...

Hot Hatch
A hot hatch (shortened from hot hatchback) is a high-performance hatchback car. The term originated in the mid-1980s; however, factory high-performance versions of hatchbacks have been produced since the 1970s. Front-mounted petrol engines, together with front-wheel drive, is the most common powertrain layout, however all-wheel drive has become more commonly used since around 2010. Most hot hatches are of European or Asian origin. __TOC__ Etymology Usage of the term "hot hatchback" began in the United Kingdom in 1983, which was shortened to "hot hatch" in 1984. The term first appeared in ''The Times'' in 1985, and is now commonly and widely accepted as a mainstream, albeit informal, term. It is retrospectively applied to cars from the late 1970s but was not a phrase used at the time. Some larger grand tourer sports cars have a rear hatch (such as the Porsche 928, Porsche Panamera, Reliant Scimitar GTE and Ferrari FF), these are hatchbacks, however it is uncommon for thes ...
