Engines used by French automaker Renault SA have historically been referenced in technical specifications along two distinct systems:

  • a purely numeric system used from the origins of the company until the mid-1980s
  • an alphanumeric system in use since then

Contents

[edit] Numbering systems

[edit] Numeric

The numeric engine referencing system used until the mid-1980s was simply the chronological sequence of engine development projects. Thus, variants based on the same engine block may have unrelated numbers.

[edit] Alphanumeric

The system in use since the mid-1980s is of the format XnY-zzz where

  • X is a letter specifying the engine family
  • n is a one-digit code specifying the engine architecture as follows:
    1. Petrol engine with single-barrel carburetor and parallel valves (a layout often but not always associated with an overhead valve design)
    2. Petrol engine with double-barrel carburetor and parallel valves
    3. Petrol engine with single- or multi-point fuel injection and parallel valves
    4. Petrol engine with four valves per cylinder
    5. Petrol engine with single-barrel carburetor and crossflow valve layout
    6. Petrol engine with double-barrel carburetor and crossflow valve layout
    7. Petrol engine with single- or multi-point fuel injection and 2 or 3 valves per cylinder in a crossflow layout (includes also an early 16-valve version of the F-type engine)
    8. Diesel engine with indirect injection (prechamber)
    9. Diesel engine with direct injection
  • Y is a one-letter indicator of displacement:
    A: under 750cc
    B-U: from 750 to 2250 cc in 50-cc, then 100-cc increments as displacement increases
    V-Z: above 2250 cc in increments larger than 100cc
  • zzz is a three-character alphanumeric code (usually starting with 7 or A) referring to key details of the variant's configuration (e.g., turbocharged, implemented in a specific vehicle, manual or automatic transmission, catalytic converter or not, etc.)

[edit] Engine families

[edit] 6DE

The 6DE engine is an overhead camshaft Diesel V6 sourced from Perkins and used in the Vel Satis sedan and Espace minivan:

  • 6DE1: 2958cc

[edit] A

The A engine was an all-aluminum overhead valve inline 4 designed in the mid-1960s for the Renault 16 and produced in three variants:

  • A1K: 1470cc
  • A1L: 1565cc
  • A2M/A3M: 1647cc

[edit] B

The B family (for the Billancourt factory where it was produced) was a cast-iron overhead valve inline-4 designed in the mid-1940s for the 4CV and also used in the Renault 4 and Dauphine:

  • 748cc (out of production before alphanumeric codes were introduced)
  • 782cc (out of production before alphanumeric codes were introduced)
  • B1B: 845cc

[edit] C

The C family (for the Cléon factory where it was produced, also referred to as Sierra in early variants) was a cast-iron overhead valve inline-4 designed in the early 1960s for the Renault 8. An extremely sturdy, low-cost design, it was continuously refined over its 35-year career and was used in every supermini and compact Renault type up to and including the 1992 Twingo:

  • C1C: 903cc
  • C1E: 1108cc
  • C1G/C3G: 1237cc
  • 1289cc (out of production before alphanumeric codes were introduced)
  • C1J/C2J/C3J: 1397cc

[edit] D

The D family is the successor to the smaller versions of Type C, introduced in the mid-1990s, and is a cast-iron overhead camshaft inline-4 that powers the Renault Twingo:

  • D4F: 1149cc
  • D7F: 1149cc

A 1000-cc D7D version was abandoned after early development.

[edit] E

The E family (for Energy) is the successor to the larger versions of Type C. It is a cast-iron overhead camshaft inline-4 introduced on the Renault 19 in 1988 and widely used in the Clio and Mégane lineups:

  • E5F/E7F: 1171cc
  • E5J/E6J/E7J: 1390cc
  • E7M/E4M: 1598cc

[edit] F

The F inline-4 family (for Fonte, French for cast iron) was the successor to the A family. Launched in 1981 on the Renault 9 and Renault 11, it has been the mainstay of Renault's engine lineup through the early 2000s in a succession of increasingly powerful petrol and Diesel variants in overhead camshaft configurations. It was also Renault's first production four-valve design. It is being replaced by the M engine.

  • F1N/F2N/F3N: 1721cc
  • F7P: 1764cc
  • F3P: 1794cc
  • F3R/F4R/F7R: 1998cc
  • F8Q/F9Q: 1896cc

[edit] G

The G engine was designed in the late 1980s to be a modular family of overhead camshaft inline 4- and 5-cylinder petrol and Diesel engines. A G7R petrol and a G8T Diesel variant were in development when Renault announced a merger with Volvo who was designing its own modular family along the exact same lines. The group made the business decision to cancel all G development save for Diesel versions. Despite the breakdown of the merger in 1993, Renault used Volvo petrol engines (Type N) in its mid- and full-size models until the early 2000s

  • G8T/G9T: 2188cc

[edit] H

The H family is a major evolution of the F family.

  • H4R: 1998cc

[edit] J

The J family (also referred to as the Douvrin engine) was an all-aluminum overhead camshaft inline-4 overhead camshaft design jointly developed with PSA. Introduced in 1977, it was phased out in 1996 by the F series.

  • J5R/J6R/J7R: 1995cc
  • J6T/J7T: 2165cc
  • J8S: 2068cc

[edit] K

The K type is a major evolution of the E type.

  • K4J: 1390cc
  • K4M: 1598cc
  • K7M: 1598cc
  • K9K: 1461cc

[edit] L

The L type is an aluminum overhead camshaft petrol V6 developed jointly with PSA, who refer to it as the ES engine:

  • L7X: 2965cc

[edit] M

The M engine is an overhead camshaft engine developed jointly with Nissan, who refers to it as the MR engine. Only one Diesel version is in use at Renault as of mid-2006, though the petrol versions already launched by Nissan will almost certainly be used as well

  • M9R: 1995cc
  • M4R: 1997cc (petrol engine used on Renault Clio III; launched november 2006)

[edit] N

The N engine is Renault's internal designation for the modular overhead camshaft inline-4 and inline-5 sourced from Volvo in the 1990s and used on the Laguna and Safrane sedans:

  • N7Q: 1948cc
  • N7U: 2436cc

[edit] S

The S engine was a cast-iron overhead valve inline-4 Diesel engine sourced from Italian engine manufacturer SOFIM. It has been used in the Trafic and Master utility van and the Safrane sedan since 1981:

  • S8U/S9U: 2445cc
  • S9W: 2799cc

[edit] V

The V engine is Renault's internal designation for the Nissan VQ engine, an overhead camshaft V6 used in the Vel Satis sedan and Espace minivan

  • V4Y: 3498cc

[edit] X

The X engine (referred to as XY by PSA) was an all-aluminum overhead camshaft inline-4 jointly developed with PSA. Introduced in 1974, it powered the ill-fated Renault 14 midsize car and was phased out in 1982 by evolutions of the C series:

  • X1G: 1219cc
  • X2J: 1360cc

[edit] Z

The Z engine, also known as the PRV V6, was a cast-iron overhead camshaft V6 developed jointly with PSA and Volvo in the early 1970s. Introduced in 1975 on the Renault 30, it also powered the 25, Safrane, Espace, and Alpine.

  • Z7U: 2458cc
  • Z6V/Z7V: 2664cc
  • Z7X: 2975, then 2963cc
