The Douvrin family was an all-aluminum inline-four automobile engine designed in the early 1970s and produced from 1977 to 1996 by Compagnie Française de Mécanique, a joint-venture between PSA and Renault located in the town of Douvrin in northern France. This engine is designed by the engineer Jean-Jacques His (father of Formula 1 engines from Renault and Ferrari). It was produced in the same factory as the PRV V6, which also is sometimes known outside France as the "Douvrin" V6. The Douvrin engine is also referred to as the ZDJ/ZEJ engine by Peugeot, and as the J-type engine by Renault.

Douvrin "Suitcase Engine"

Constructed from aluminium alloy, chain driven overhead camshaft, with gearbox in the sump sharing engine oil for lubrication, typically mounted almost on its side. For this reason it is often nicknamed the "suitcase engine" owing to the way in which the engine has to be split open in order service the transmission. It was available with versions from 954cc to 1360cc.

2.0

The 2.0 L (1995 cc) was an oversquare design with a single belt driven overhead camshaft, an 88 mm (3.5 in) bore, and an 82 mm (3.2 in) stroke.

Though somewhat dull (with a 6,000 rpm redline only) and slow to throttle response, the normally aspirated 8-valve versions proved extremely reliable. Mileages of over 300,000 km (190,000 mi) without major repairs are not uncommon. The 12-valvers are much livelier and also boast above-average reliability. The turbocharged versions have only average reliability.

Renault

It was produced in a variety of configurations for Renault:

  • normally aspirated 8-valve, single-barrel carburetor, 90 CV (66 kW; 89 hp), from 1978 to 1993
  • normally aspirated 8-valve, double-barrel carburetor, 110 CV (81 kW; 108 hp), from 1977 to 1992
  • normally aspirated 8-valve, multipoint fuel injection, 120 CV (107 with catalytic converter), from 1986 to 1996
  • normally aspirated 12-valve, multipoint fuel injection, 140 CV (103 kW; 138 hp), (136 PS with catalytic converter), from 1989 to 1996
  • turbocharged 8-valve, multipoint fuel injection, 175 CV (162 with catalytic converter), from 1987 to 1993
  • In the following models:

  • Renault 18
  • Renault 20
  • Renault 21
  • Renault 25
  • Renault Espace
  • Renault Fuego
  • Renault Safrane
  • Renault Trafic
  • Others

  • SIMI Cournil SCE15/25
  • Auverland SC 11/200/250
  • 2.2

    The 2.2 L (2165 cc) version was derived from the 2.0 L by a simple stroke extension from 82 to 89 mm (3.5 in), making it an undersquare design. Most parts, including the cylinder head, were identical to the 2.0 L's.

    This engine proved as reliable as its 2.0 L counterpart. It is often confused with the somewhat similar Simca Type 180, which displaced 2155 cc.

    Renault

    It was produced in fewer configurations than the smaller version for Renault:

  • normally aspirated 8-valve, double-barrel carburetor, 110 CV (81 kW; 108 hp), from 1977 to 1992
  • normally aspirated 8-valve, multipoint fuel injection, 121 CV (107 with catalytic converter), from 1983 to 1996
  • normally aspirated 12-valve, multipoint fuel injection, 137 CV (101 kW; 135 hp), from 1989 to 1996
  • In the following models:

  • Renault Fuego
  • Renault 18
  • Renault 20
  • Renault 21
  • Renault 25
  • Renault Master
  • Renault Medallion
  • Renault Safrane
  • Others

  • 1987-1989 Eagle Medallion
  • 1985-1992 Winnebago LeSharo (built on Trafic chassis and cab)
  • 1985-1992 Itasca Phasar (built on Trafic chassis and cab)
  • 2.1 Diesel

    The 2.1 L (2068 cc) Diesel version was derived from the 2.0 L petrol version by a bore reduction from 88 to 86 mm (3.4 in) and a stroke extension from 82 to 89 mm (3.5 in). Cast-iron cylinder liners were used to withstand the higher cylinder pressure of Diesel combustion. The cylinder head was of course specific and was a Ricardo-type prechamber design fed by a mechanically controlled fuel pump. This engine was only used by Renault in three versions:

  • normally aspirated 8-valve, 64 PS (47 kW; 63 hp), from 1979 to 1992
  • turbocharged 8-valve, 88 PS (65 kW; 87 hp), from 1982 to 1992
  • turbocharged 8-valve with variable-nozzle turbocharger, 92 PS (68 kW; 91 hp), from 1990 to 1996
  • Reliability of all Diesel versions has been not so good, lots of problem at the cylinder head and block connection has been verified (usually around 200.000 km), often the prechamber number 3 present cracks, requiring a head change, especially on Jeeps due to an excessive mass for this engine [citation needed]
