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.

2.1 Diesel

The Diesel version was derived from the petrol version by a bore reduction from and a stroke extension from. 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:
