ENGINES BY RENAULT
« on: 22:41, Thu 24 July 2008 »
Hi all,
I came across this the over night on the net.

ENGINES BY RENAULT


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





Numbering systems
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.


Alphanumeric
The system in use since the mid-1980s is of the format XnY-zzzwhere

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.)

Engine families

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

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

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

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

DThe 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.


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

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

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

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

H4R: 1998cc

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

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

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

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

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)

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

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

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

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

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
