Douvrin engine
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. 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 gearbox setup, and was longitudinally or transversely mounted depending on car model.
