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 distribution 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[edit]

In December 1982,[1] the Renault Board proposed a new 1596 cm3 diesel 55 bhp for the Renault 9. It will be known as "F8M" 2. The new 1.6 D designed by engineer George Douin and his team engine turns a page in the history of Renault, the latter effect was not long ago created an entirely new engine design fully Renault. In addition, this unique diesel break with some old habits home, especially regarding the machining of cylinder engine since it has no removable shirts so often touted by Renault to promote easy exchange so-called " shots whip " technicians considered that this argument had lost much of its appeal thanks to advances in technology metals that significantly slow the wear of rubbing parts machined. This modern 4- cylinder naturally adopts a camshaft in head which the drive is operated through a toothed belt that also controls diesel injection pump. A second belt rotates the alternator and water pump, while a vacuum pump located at the rear for the brake assist by Master Vac. The cast iron block is topped by a light alloy cylinder head Ricardo Comet prechamber. In practice, this new engine will prove little greedy. This is the first real diesel Renault engine, since the engine J8S 2.1 D Renault 20 and Renault 30 was produced by the French Society of Mechanical. The engine of the Renault F8M 9 is disposed under the hood transversely inclined at 12 ° towards the rear. A few months after the release of the Renault 9 Diesel, the Renault 11 was launched in April 1983, which will adopt the new diesel later in the fall of 1983.

In the fall of 1983, Renault launched its new petrol engine " F2N " of 1721 cm3 with dual carburetor body whose base is that of F8M 1.6- D, it has an architecture with diesel-type combustion chambers integrated with pistons, which is not common on a petrol engine. He appears on " Renault 11 GTX ", " Renault 11 TXE " futuristic " R11 TXE Electronic " with digital meter and speech synthesis. In February 1984, the Renault 9 in turn adopts the " F2N " 1.7-liter engine for its new versions " R9 GTX " and " R9 TXE ." Until the arrival of F2N engine, the Renault 9 and Renault 11 species, were equipped only Cléon-Fonte engine 1108 cm3 and 1397 cm3 with lateral camshaft, which were of old design, since this engine had appeared in 1962 on the Renault 8 and Renault Floride. For the highest ranges of the Renault 9 and Renault 11 versions, it was necessary to have a more powerful engine and especially more modern design, which is the role of F2N engine, Renault no longer wish to use the "Cléon-Alu engine" of the Renault 18, which was also old design. Versions Cléon-Fonte engines are naturally preserved and also later versions sport " Renault 9 Turbo " and " Renault 11 Turbo " will be equipped with Cléon-Fonte 1.4-liter engine with a Garrett turbo.

F2N in that the motor is designed on a diesel engine, makes it a very strong engine, but with the bolt in its design which places the manifold just above the exhaust manifold, causing heating the base of the carburetor has long deforms and created an area outlet.

Thereafter, the F8M D 1.6 diesel engine will also equip the Super 5 Express (Rapid / Extra), and the Volvo 340 and Volvo 360. The petrol engine of 1721 cm3 F2N equip Renault 21, Super 5, Renault 19, Clio 1, Volvo 340, Volvo 360 and also the Volvo 440, 460 and 480 Coupe (in this Volvo engine will name B18KP). A version with single -barrel carburetor of 1721 cm3 petrol Renault Trafic equip some 1 and some R21, it will take the engine such as " F1N ." The 1721 cm3 petrol version also exists mutipoint injection, it will take the engine such as " F3N " will equip the U.S. versions of Renault 9 and Renault 11 (Renault Alliance and Renault Encore) or U.S. R21 (Renault Medallion) and Renault Super 5 11 GTE and GTE will be sporting versions of R11 and Super 5 in some countries such as Switzerland and Germany, as turbo engines carburetor no longer meet the pollution standards in these countries, so the Super 5 GTE will be sold instead of the Super 5 GT Turbo and GTE R11 instead of R11 Turbo.

Volvo turbo even grafted on 1721 cm3 with multipoint fuel injection and engine types will "B18FT" (name Volvo), and equip the coupe Volvo 480 Turbo, the 440 Turbo Volvo and Volvo 460 Turbo. These engines are often sought to make swaps on Super 5 GT Turbo, Renault 9 Turbo and Renault 11 Turbo.

Nowadays the engine's are produced in the engine manufacturing facility at Cléon, near to Rouen in Normandy.[2]

Evolution[edit]

Diesel versions[edit]

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[edit]

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 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 Renault's K engine.

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.
