Renault F-Type engine

F Renault engine is an automotive internal combustion engine, four-stroke, with 4 cylinders in line bored directly into the iron block, water cooled, with tree (s) driven overhead camshafts (s) by a timing belt with an aluminum cylinder head, overhead valve, developed and produced by Renault in the early '80s, making its appearance on the Renault 9 and Renault 11. This engine is available in petrol and diesel versions, with 8 or 16 valves.

History

In December 1982,^[1] the Renault Board proposed a new 1596 cm³ diesel engine with 55 bhp for the Renault 9. Known as "F8M", the new engine was designed by engineer George Douin and his team and broke with tradition by featuring no removable cylinder liners, thanks to advances in metals technology that significantly slow the wear of rubbing mechanical parts. The new 4- cylinder unit adopted an overhead camshaft driven by a toothed belt that also controls the diesel injection pump. A second belt rotates the alternator and water pump, while a vacuum pump located at the rear operates the brake servo. The cast iron block is topped by a light alloy cylinder head featuring Ricardo Comet prechambers. The engine is mounted transversely inclined rearwards 12°. A few months after the release of the Renault 9 Diesel, the Renault 11 was launched in April 1983, the diesel version being introduced in autumn 1983.

In the autumn of 1983, Renault launched the 1721 cc F2N petrol engine, using the block of the F8M.^[2] It has a diesel-type architecture, with combustion chambers integrated with the piston design. Since the petrol version does not require water channels in the block, a bigger bore was possible than in the smaller diesel version. It first appeared in twin carburettor form in the Renault 11 GTX, TXE, and the TXE Electronic with digital meter and speech synthesis. In February 1984, " F2N " was added to the Renault 9 GTX and TXE.

Thereafter, the F8M was also used in the Renault 5 Express (Rapid / Extra), and the Volvo 300 series. The F2N was installed in the Renault 21, Renault 5, Renault 19, Renault Clio, Volvo 340/360 and also the Volvo 400 series (designated B18KP by Volvo). A version with a single-barrel carburetor was installed in some early Renault Trafic models and some R21, called the F1N. The 1721 cc petrol version was also built with multipoint injection as the F3N. This was fitted to the U.S. versions of the Renault 9 and Renault 11 (Renault Alliance and Encore), as well as to GTE models of the Renault 5 and 11 sold in some countries such as Switzerland and Germany - as the old carburetted Cleon-Fonté turbo engines no longer met the pollution standards in these countries.

Volvo built turbocharged versions of the F2N with multipoint fuel injection (designated "B18FT"), featured in the Volvo 480 Turbo, the 440 Turbo Volvo and Volvo 460 Turbo. These engines are sought after to fit to Renault 5 GT Turbo, Renault 9 Turbo and Renault 11 Turbo.

Production is centred on Renault's engine manufacturing facility at Cléon, near to Rouen in Normandy.^[3]

Evolution

Diesel versions

Beginning in 1987, the 1.6D undergoes changes to make it more quiet. This F8M second generation will unfortunately weaker at the cylinder head and head gasket. More asbestos will be dropped, which will exacerbate the problems of cylinder head gaskets. Externally, a second generation F8M detected by its cylinder head cover 6 which is secured by small screws, while a first generation F8M 3 has closed nuts for securing the valve cover, the housing for dispensing a F8M second generation part has a non-painted around the injection pump, while a first generation F8M the casing has completely black distribution.

In 1988, Renault launched the Renault 19 in place of R9 and R11, the F8M 1.6 D developing 55 bhp diesel engine of its predecessors is not powerful enough to equip the heavier R19, Renault changes the race and bore of 1.6 D, to obtain 1870 cm³ (1.9 D) which will give rise to F8Q developing 65 hp. This engine will also equip engine eventually the Clio 1, Clio 2 Express (Rapid / Extra), R21, Kangoo, Megane 1 and Traffic 1. A deflated version producing 55 Ch din will appear in the 90s. The problems keep F8Q heads and heads of seals F8M second generation.

At the end of 1988, a turbocharged version of the 1.9 D is sold on the R19, the engine will F8QT engine types, it will develop 95 HP din. It will also equip Megane 1, and the Volvo 440, Volvo 460, Volvo S40 and V40.

In the fall of 1997, Renault team are 1.9 dT a Direct injection, which gave birth to the first Renault engine with direct injection, the 1.9 dTi, it will take F9Q engine types. It will equip the Mégane 1 1 Scénic, Laguna 1, Clio Kangoo 1 and 2, and the Volvo S40 and V40.

In July 1999, his team 1.9 dTi the principle of common rail (common rail) high pressure, giving birth to the first dCi engine, the 1.9 dCi kind F9Q. It will appear on the Laguna 1 Phase 2. The 1.9 dCi also equip the last two phases 1 Mégane Scénic 1 Phase 2, Laguna 2, 2 Mégane, Scénic 2, Area 3, Area 4, Traffic 2, Master 2, Volvo S40, Volvo V40, Suzuki Grand Vitara, and Nissan Primera ...

Gasoline versions

In 1986, the Renault 21, 2.0 appears, with a displacement of 1965 cm³, F2R type such as a twin-barrel carburetor and F3R type injection version. The F3R of 1965 cm³ also equip Renault Alliance GTA in North America.

In 1989, Renault launched the sports version of the Renault 19, replacing the Renault 9 Turbo and Renault 11 Turbo. Renault abandons its legendary 1.4 Cléon-Fonte turbo carburetor in favor of a multi-valve engine and multipoint injection, it will be an evolution of the engine of 1721 cm³ F2N, the race remains the same, but the bore is increased, giving a displacement of 1764 cm³, topped by a 16-valve cylinder head that will equip the R19 16S. This engine F7P 140 bhp also equip the Clio 16S in February 1991, replacing the Super 5 GT Turbo. In July 1992, the Clio 16S and 16S R19 are fitted as standard with a catalytic converter, in order to comply with pollution standards applicable to 1 January 1993, which makes them lose 3 c.

Clio Williams appeared in 1993. As its name suggests it, the Renault Clio Williams was not designed to celebrate titles gleaned in Formula 1 with the team of Frank Williams, but before any approval for competition (2500 minimum copies required). In order to run in Group A, Renault needs a 2.0-liter engine to be the best equipped in its class. So starting the engine block F7P the Renault Clio 16S Renault will develop its 1998 cm³ F7R 150 bhp. The increase in capacity will then pass logically by reaming of 0.7 mm and with the adoption of a Clio diesel crankshaft to get the race 83.5 to 93 mm. This crankshaft "road" original thus better cash constraints to the increased torque will now reach 175 Nm at 4 500 r / min. The F7R also equip Mégane 1 and Renault Spider off

At 1 January 1993, all species cars must be equipped with a fuel injection system and a catalytic converter, on this occasion the F2N of 1721 cm³ see its increased bore and has a cylinder capacity of 1794 cm³. It will bring the engine such as "F3P" on the Renault Clio 1 and 19, and "B18U" on the Volvo 440 and Volvo 460. In contrast, the Renault 21, then at retirement retains its 1721 cm³, but with the injection (type motor F3N), Volvo will also retain the 1721 cm³ injection (type motor B18EP), alongside the new 1794 cm³. In 1994, the Laguna will be equipped with one engine F3P.

Volvo also marketed a 1596 cc petrol version with multipoint injection, sold as the "B16F" in Volvo nomenclature. It was installed in the Volvo 440 and 460 models. Peculiarly, this engine has the same bore and stroke (and resulting displacement) as the diesel F8M engine.

Version 8 valves engine F7R Clio Williams 115 bhp will appear on Laguna 1, it will also equip the Mégane 1 Scenic Area 1 and 3, it will be known as "F3R." The Volvo 440, 460 and 480, this engine will be known as "B20F". The new 1998 cc F3R replaced the old 1965 cc F3R engine.

The F4P first appeared in 1998, in the Phase 2 model of the first generation Laguna. This new 16 valve 1.8 (1783 cc) also equips the first Mégane Scénic and the second generation Laguna. At the same time, the bigger F4R is installed in the Laguna and Espace (third generation), the engine is the same size as the F7R (1998 cc) as in the Clio Williams. It ends up also being installed in the second and third generation Mégane as well as the second Laguna. The specificity of F4P and F4R engines is that they have a 16-valve cylinder head, similar to the K4J and K4M versions of K-Type engine, over the F4P and F4R engines share the same distribution kit and even water pump that K-Type engine 16 valves (K4J and K4M).

In 1999, the F5R engine appeared. This is an F7R engine, equipped with direct injection. This 16 valve DI engine is installed in the Megane coupé and convertible, as well as the Laguna 2. This was the first production French petrol engine with direct injection.

In 2001, Renault launched the Clio 2 RS, powered by the 1998 cc F4R 16 valve engine with 172 PS (127 kW). This was developed from the F7R engine of the Clio Williams. In 2004, the Phase 3 version of the Clio 2 RS gained 10 horsepower for a total of 182 PS (134 kW). Power increased further in 2006 for the Clio 3 RS, now with 197 PS (145 kW), increased again to 203 PS (149 kW) for the Phase 2 model of the third generation Clio RS.

The F4R will also be grafted with a turbo, and will be known F4Rt it will equip two Mégane, Laguna 2, Laguna 3 Avantime and Vel Satis, but especially this basis used for the Megane 2 RS 225 hp (230 hp version of the F1 Team R26 and R26.R).

The Megane RS 3 is presented in March 2009 at the Geneva show, it is equipped with the 2.0 16V Turbo block F4Rt the Megane 2 RS, increased to 250 hp. In June 2011, Renault launched a limited edition "RS Trophy 'power increases by 15 hp to 265 hp.
