Renault Cléon-Fonte Engine
The Cléon-Fonte engine, also known as the Sierra engine or under the code "C-engine" or "C-Type" (C for Cléon, where it was built, ''fonte'' being French for cast iron), is a family of four-cylinder, Straight engine, inline automobile internal combustion engine, engines manufactured continuously by Renault and its subsidiary Automobile Dacia, Dacia from 1962 to 2004. For about three decades it was a mainstay in Renault's subcompact, compact models, before being gradually replaced by the Renault Energy engine, E-type engine from the late 1980s onward. The C-type is an overhead valve, water-cooled design, with a 5-bearing crankshaft, a chain driven, side-positioned camshaft operating the valves via pushrods and Rocker arm, rockers, and an aluminum cylinder head. History When production started in 1962, this (then) modern engine was initially called the "Sierra"; it was soon renamed the "Cléon-Fonte", taking its name from the ultra-modern Renault factory where it was first manuf ...

Inline-four Engine
A straight-four engine (also called an inline-four) is a four-cylinder piston engine where cylinders are arranged in a line along a common crankshaft. The vast majority of automotive four-cylinder engines use a straight-four layout (with the exceptions of the flat-four engines produced by Subaru and Porsche) and the layout is also very common in motorcycles and other machinery. Therefore the term "four-cylinder engine" is usually synonymous with straight-four engines. When a straight-four engine is installed at an inclined angle (instead of with the cylinders oriented vertically), it is sometimes called a slant-four. Between 2005 and 2008, the proportion of new vehicles sold in the United States with four-cylinder engines rose from 30% to 47%. By the 2020 model year, the share for light-duty vehicles had risen to 59%. Design A four-stroke straight-four engine always has a cylinder on its power stroke, unlike engines with fewer cylinders where there is no power stroke occu ...

Overhead Valve
An overhead valve (OHV) engine, sometimes called a ''pushrod engine'', is a piston engine whose valves are located in the cylinder head above the combustion chamber. This contrasts with earlier flathead engines, where the valves were located below the combustion chamber in the engine block. Although an overhead camshaft (OHC) engine also has overhead valves, the common usage of the term "overhead valve engine" is limited to engines where the camshaft is located in the engine block. In these traditional OHV engines, the motion of the camshaft is transferred using pushrods (hence the term "pushrod engine") and rocker arms to operate the valves at the top of the engine. Some early intake-over-exhaust engines used a hybrid design combining elements of both side-valves and overhead valves. History Predecessors The first internal combustion engines were based on steam engines and therefore used slide valves. This was the case for the first Otto engine, which was first succ ...

Renault 5
The Renault 5 is a four-passenger, three or five-door, front-engine, front-wheel drive hatchback supermini manufactured and marketed by the French automaker Renault over two generations: 1972–1985 (also called R5) and 1984–1996 (also called Super 5 or Supercinq). The R5 was marketed in the US and Canada as Le Car, from 1976 through 1983. Renault marketed a four-door sedan variant, the Renault 7, manufactured from 1974 until 1984 in Spain by Renault's subsidiary FASA-Renault and exported to select markets. The Renault 5 became the best-selling car in France from 1972 until 1986, with a total production exceeding 5.5 million over a 14-year period, making it France's most popular car. First generation (1972–1985) The first images and details of the Renault 5 were published on 10 December 1971, and the car's formal launch followed on 28 January 1972. The Renault 5 was styled by Michel Boué, who designed the car in his spare time, outside of his normal duties. When Renault e ...

Automatic Gearbox
An automatic transmission (sometimes abbreviated to auto or AT) is a multi-speed transmission used in internal combustion engine-based motor vehicles that does not require any input from the driver to change forward gears under normal driving conditions. It typically includes a transmission, axle, and differential in one integrated assembly, thus technically becoming a transaxle. The most common type of automatic transmission is the hydraulic automatic, which uses a planetary gearset, hydraulic controls, and a torque converter. Other types of automatic transmissions include continuously variable transmissions (CVT), automated manual transmissions (AMT), and dual-clutch transmissions (DCT). An electronic automatic transmission (EAT) may also be called an electronically controlled transmission (ECT), or electronic automatic transaxle (EATX). A hydraulic automatic transmission may also colloquially called a " slushbox" or simply a "torque converter", although the latter term can ...

Manual Transmission
A manual transmission (MT), also known as manual gearbox, standard transmission (in Canada, the United Kingdom, and the United States), or stick shift (in the United States), is a multi-speed motor vehicle transmission (mechanics), transmission system, where gear changes require the driver to manually select the gears by operating a gear stick and clutch (which is usually a foot pedal for cars or a hand lever for motorcycles). Early automobiles used ''sliding-mesh'' manual transmissions with up to three forward gear ratios. Since the 1950s, ''constant-mesh'' manual transmissions have become increasingly commonplace and the number of forward ratios has increased to 5-speed and 6-speed manual transmissions for current vehicles. The alternative to a manual transmission is an automatic transmission; common types of automatic transmissions are the Automatic transmission#Hydraulic automatic transmissions, hydraulic automatic transmission (AT), and the continuously variable transmissio ...

Fuel Injection
Fuel injection is the introduction of fuel in an internal combustion engine, most commonly automotive engines, by the means of an 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 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 carburettors 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 a carburettor relies on suction created by intake ai ...

Twingo
The Renault Twingo is a four-seater passenger city car manufactured and marketed by the French auto-maker Renault, introduced in 1992 and currently in its third generation. The first generation Twingo (two door, front engine) debuted at the Paris Motor Show on 5 October 1992, receiving its formal market launch in continental European markets beginning in April 1993. Renault launched the second-generation Twingo (two door, front engine) in the summer of 2007 – and the third generation (four door, rear engine) debuted at the 2014 Geneva Motor Show, receiving its formal market launch in September 2014. The name ''Twingo'' is a portmanteau of the words ''twist'', ''swing'' and ''tango''. First generation (1993) The original Twingo was launched in April 1993, was sold in Europe's LHD markets until August 2007, and received intermediate restylings in 1998, 2000 and 2004. Development Designed under the direction of Patrick Le Quément, Renault's chief designer, the car derive ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cylinder Head
In an internal combustion engine, the cylinder head (often abbreviated to simply "head") sits above the cylinders and forms the roof of the combustion chamber. In sidevalve engines, the head is a simple sheet of metal; whereas in more modern overhead valve and overhead camshaft engines, the cylinder head is a more complicated block often containing inlet and exhaust passages, coolant passages, valves, camshafts, spark plugs and fuel injectors. Most straight engines have a single cylinder head shared by all of the cylinders and most V engines have two cylinder heads (one per bank of cylinders). Design A summary of engine designs is shown below, in chronological order for automobile usage. Sidevalve engines In a flathead (''sidevalve'') engine, all of the valvetrain components are contained within the block, therefore the head is usually a simple sheet of metal bolted to the top of the engine block. Sidevalve engines were once universal in automobiles but are now lar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rocker Arm
In the context of an internal combustion engine, a rocker arm is a valvetrain component that typically transfers the motion of a pushrod to the corresponding intake/exhaust valve. Rocker arms in automobiles are typically made from stamped steel, or aluminum in higher-revving applications. Some rocker arms (called ''roller rockers'') include a bearing at the contact point, to reduce wear and friction at the contact point. Overview In the typical use-case of an overhead valve (pushrod) engine, the camshaft at the bottom of the engine pushes the pushrod upwards. The top of the pushrod presses upwards on one side of the rocker arm (located at the top of the engine), which causes the rocker arm to rotate. This rotation causes the other end of the rocker arm to press downwards on the top of the valve, which opens the valve by moving it downwards. A ''roller rocker'' is a rocker arm that uses needle bearings (or a single bearing ball in older engines) at the contact point between the ...
