The Douvrin family is 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.

Construction

This engine had an aluminium alloy block with cast iron liners, and an aluminium alloy head with one overhead camshaft driven by belt. Its displacement varied from 1995 to 2165 cc. This engine should not be confused with the PSA-Renault X-Type engine whose displacement varied from 954 to 1360 cc and had a gearbox integrated to the block. The Douvrin engine on the contrary, had a conventional (external) gearbox setup, and was longitudinally or transversely mounted depending on car model.

2.0

The 1995 cc was an oversquare design with a single belt driven overhead camshaft, an 88x82 mm bore and stroke.

Applications

PSA

Renault

It was produced in a variety of configurations for Renault:

2.2

The 2165 cc version was derived from the 1995 cc by a stroke extension from 82 to 89 mm, making it an undersquare design. Most parts, including the cylinder head, were identical to those of the 2-liter unit. This engine proved as reliable as its 2.0-liter counterpart. It is often confused with the somewhat similar 2.2 litre Chrysler Type 180 engine, which displaced 2155 cc

Applications

PSA

Renault

Renault offered the 2.2 in fewer configurations than the smaller version:

2.1 Diesel

The 2068 cc Diesel version was derived from the 1995 cc petrol version by a bore reduction from 88 to 86 mm and a stroke extension from 82 to 89 mm. Cast-iron cylinder liners were used to withstand the higher compression ratio of Diesel combustion. The cylinder head was a Ricardo-type pre-chamber design fed by a mechanically controlled fuel pump. This engine was only used by Renault in three versions:
