List of Renault engines

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[edit]

Numeric[edit]

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[edit]

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 (includes also a direct petrol injection F engine)
    6. Petrol engine with double-barrel carburetor and crossflow valve layout
    7. Petrol engine with multi-point fuel injection with half-spherical combustion chambers and 2 valves per cylinder (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 750 cc
    B-U: from 750 to 2,250 cc in 50 cc, then 100 cc increments as displacement increases
    V-Z: above 2250 cc in increments larger than 100 cc
  • 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. An odd number refers to an engine configured for automatic transmission, while an even number is meaning manual gearbox.)

Engine families[edit]

A[edit]

Main article: Renault A-Type engine

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

  • A1K: 1,470 cc

  • AxM: 1,647 cc

B[edit]

The B family (for the Billancourt factory where it was produced,[1] also referred to as the Ventoux engine) was a cast-iron overhead valve 3-bearing crankshaft inline-4 designed in the mid-1940s for the 4CV and also used in the Renault 4 and Dauphine:
