ProductsDouvrin engine series (inline four-cylinder engines)
ParentPSA Peugeot Citroën and Renault joint collaboration

The Douvrin engine series consists of all-aluminum inline four-cylinder units produced between 1977 and 1996 by Compagnie Française de Mécanique, a joint collaboration of PSA Peugeot Citroën and Renault, located in Douvrin, northern France. Engineered by Jean-Jacques His, this powerplant was assembled alongside the PRV engine V6, which is also referred to as the "Douvrin" V6 outside of France. Peugeot designates it as the ZDJ/ZEJ engine, whereas Renault identifies it as the J-type.

Construction

The Douvrin engines feature an aluminum alloy block equipped with cast iron cylinder liners and an aluminum cylinder head incorporating a single overhead camshaft actuated by a timing belt. Their displacement spans from 1995 cc to 2165 cc. Unlike the smaller PSA-Renault X-Type engine (ranging from 954 cc to 1360 cc), which integrates the gearbox within the engine assembly, the Douvrin uses a traditional external transmission system and can be installed either longitudinally or transversely depending on the vehicle application.

2.0

This particular variant employs an oversquare configuration with a single overhead camshaft driven by a belt, featuring specific bore and stroke dimensions.

Renault

Renault offered this engine in several configurations:

  • Naturally aspirated 8-valve with a single-barrel carburetor, , produced from 1978 to 1993
  • Naturally aspirated 8-valve with double-barrel carburetor, , available between 1977 and 1992
  • Naturally aspirated 8-valve featuring multipoint Bosch L(U/E) Jetronic fuel injection, (with catalytic converter), from 1984 to 1989 (catalytic converters mandated in North America)
  • Naturally aspirated 8-valve with multipoint BENDIX ECU-controlled fuel injection, (with catalytic converter), produced between 1989 and 1996
  • Naturally aspirated 12-valve version equipped with multipoint fuel injection, (with catalytic converter), manufactured from 1989 to 1996
  • Turbocharged 8-valve model with multipoint fuel injection, (with catalytic converter), offered between 1987 and 1993 (catalytic converters required following EC regulations from model year '89; compliant with EURO III standards)

This engine powered various Renault models such as:

Others

Additional applications include:

2.2

The enlarged version of this engine was created by extending the stroke from to mm, resulting in an undersquare layout while retaining many parts from the 2.0-liter variant, including the cylinder head design.

This iteration preserved a reliability level similar to that of the smaller displacement unit and is frequently mistaken for the Chrysler Type 180 engine, which has a comparable displacement.

Renault

The 2.2-liter engine from Renault was available in fewer variants compared to the smaller displacement model:

  • Naturally aspirated with 8 valves and a double-barrel carburetor, produced between 1977 and 1992
  • Naturally aspirated with 8 valves and multipoint fuel injection, including versions equipped with a catalytic converter, offered from 1983 to 1996
  • Naturally aspirated with 12 valves and multipoint fuel injection, manufactured from 1989 through 1996



Additional Applications

2.1 Diesel

The Diesel variant was developed from the petrol engine by decreasing the bore from 88 mm to 86 mm while increasing the stroke from 79 mm to 90 mm. To withstand the higher compression of Diesel operation, cast-iron cylinder liners were implemented for enhanced durability. The cylinder head incorporated a Ricardo-style pre-chamber design paired with a mechanically governed fuel pump. Renault provided three main versions:

  • Naturally aspirated with 8 valves, delivering , produced between 1979 and 1992
  • Turbocharged with 8 valves, generating , available from 1982 to 1992
  • Turbocharged with an 8-valve variable-nozzle turbocharger, producing , manufactured between 1990 and 1996

The Garrett T2 turbocharged model was utilized by AMC-Renault for Jeep Wagoneer, Cherokee, and Comanche vehicles during the years 1984 to 1987. Meanwhile, the Garrett T3 turbocharged engine powered AMC-Renault’s Winnebago Lesharo and Itasca Phasar (1983–1986), both based on the front-wheel-drive Renault Trafic I platform featuring long wheelbases.
